The Pug Loader renders Pug templates into HTML or compiles it into a template function.
- Resolves paths and aliases for extends, include.
- Resolves source asset files in tag attributes via require() function.
- Resolves source JS/JSON files in Pug code via require() function.
- Resolves alias from webpack resolve.alias or tsconfig.json.
- Renders Pug template into pure HTML string.
- Compiles Pug template into template function for render template in the browser.
- Generates a template function with both CommonJS and ESM syntax.
- Pass data into template from the loader options.
- Build-in Pug filters:
:escape
:code
:highlight
:markdown
with highlighting of code blocks - Supports an indent in Vue template, see source of an example.
- Watching of changes in all dependencies.
Warning

Note
Instead of
html-webpack-plugin
recommended to use pug-plugin or html-bundler-webpack-plugin .The Pug Plugin allow to use a template as an entrypoint and generates static HTML or template function from Pug template containing source files of scripts, styles, images, fonts and other resources, similar to how it works in Vite.
Please see usage examples and the demo app Hello World.

Choose your way:
- Using the pug-plugin. It is a very easy intuitive way.
- Using the html-webpack-plugin with the pug-loader. It is a very complex non-intuitive way.
Using only the pug-plugin
The pug-plugin contains already the pug and pug-loader packages. For details and examples please see the pug-plugin site.
Install the pug-plugin
:
npm install pug-plugin --save-dev
Install additional packages for styles:
npm install css-loader sass-loader sass --save-dev
Start with a Pug template. Add the link
and script
tags.
You can include asset source files such as SCSS, JS, images, and other media files directly in a Pug template.
The plugin resolves script(src="...")
link(href="...")
and img(src="..." srcset="...")
that references your script, style and image source files.
For example, there is the template ./src/views/home.pug:
html
head
//- variable from Webpack config
title= title
//- relative path to favicon source file
link(href="./favicon.ico" rel="icon")
//- relative path to SCSS source file
link(href="./style.scss" rel="stylesheet")
//- relative path to JS source file -->
script(src="./main.js" defer="defer")
body
h1 Hello World!
//- relative path to image source file
img(src="./picture.png")
All source filenames should be relative to the entrypoint template, or you can use Webpack alias. The references are rewritten in the generated HTML so that they link to the correct output files.
The generated HTML contains URLs of the output filenames:
<html>
<head>
<title>Homepage</title>
<link href="img/favicon.3bd858b4.ico" rel="icon" />
<link href="css/style.05e4dd86.css" rel="stylesheet" />
<script src="js/main.f4b855d8.js" defer="defer"></script>
</head>
<body>
<h1>Hello World!</h1>
<img src="img/picture.58b43bd8.png" />
</body>
</html>
If the entry
plugin option is a path, the plugin finds all templates automatically
and keep the same directory structure in the output directory.
If the entry
plugin option is an object, the key is an output filename without .html
extension and the value is a template file.
Very simple and clear webpack.config.js, all relevant settings are in one place, in plugin options:
const path = require('path');
const PugPlugin = require('pug-plugin');
module.exports = {
output: {
path: path.join(__dirname, 'dist/'),
},
plugins: [
new PugPlugin({
// automatically processing all templates in the path
entry: 'src/views/',
// - OR - define many pages manually (key is output filename w/o `.html`)
entry: {
// simple page config w/o variables
index: 'src/views/home.pug', // => dist/index.html
// advanced page config with variables
'news/sport': { // => dist/news/sport.html
import: 'src/views/news/sport/index.pug', // template file
data: { title: 'Sport news' }, // pass variables into template
},
},
data: {...}, // pass global data into all templates
js: {
// JS output filename, used if `inline` option is false (defaults)
filename: 'js/[name].[contenthash:8].js',
//inline: true, // inlines JS into HTML
},
css: {
// CSS output filename, used if `inline` option is false (defaults)
filename: 'css/[name].[contenthash:8].css',
//inline: true, // inlines CSS into HTML
},
})
],
module: {
rules: [
{
test: /\.(s?css|sass)$/,
use: ['css-loader', 'sass-loader']
},
{
test: /\.(ico|png|jp?g|webp|svg)$/,
type: 'asset/resource',
generator: {
filename: 'img/[name].[hash:8][ext][query]',
},
},
],
},
};
Note
No additional plugins or loader required.
Using with html-webpack-plugin
Warning
This way is not recommended!
Install the @webdiscus/pug-loader
only if you use the html-webpack-plugin
.
npm install @webdiscus/pug-loader html-webpack-plugin --save-dev
Install additional packages for styles:
npm install css-loader sass-loader sass --save-dev
Install additional plugin to extract CSS:
npm install mini-css-extract-plugin --save-dev
Using the html-webpack-plugin
you should require a source asset file in the Pug template.
For example, there is the template ./src/views/home.pug:
html
head
//- variable from plugin options, very ugly access
title= htmlWebpackPlugin.options.data.title
//- relative path to favicon source file
link(href=require("./favicon.ico") rel="icon")
//- JS and CSS will be injected into HTML automatically, anywhere here
//- Note: you have no control over the position or order of injected files
body
h1 Home
//- relative path to image source file
img(src=require("./picture.png"))
Very complex webpack.config.js:
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
module.exports = {
output: {
path: path.join(__dirname, 'dist/'),
// JS output filename must be defined only here
filename: 'js/[name].[contenthash:8].js',
},
entry: {
// Source files of styles and scripts must be defined here, separately from their templates.
// How to bind each generated bundle to the HTML page?
// Answer: using the `chunks` plugin option.
index: ['./src/views/home/main.js', './src/views/home/style.scss'],
'news/sport': ['./src/views/news/sport/main.js', './src/views/news/sportstyle.scss'],
},
plugins: [
// For one page must be initialized the plugin instance.
new HtmlWebpackPlugin({
template: path.join(__dirname, 'src/views/home/index.pug'),
// HTML output filename
filename: 'index.html',
// bind the generated JS and CSS files to this template via chunks,
// this is a very terrible "crutch"
chunks: ['index'],
// pass variables into template,
// access in template is very ugly: `htmlWebpackPlugin.options.data.title`
data: { title: 'Home' }
}),
// For other page must be initialized yet one plugin instance.
// It's very very bad practice and ugly syntax!
new HtmlWebpackPlugin({
template: path.join(__dirname, 'src/views/news/sport/index.pug'),
// HTML output filename
filename: 'news/sport.html',
// bind the generated JS and CSS files to this template via chunks option,
// you're not confused yet using chunks?
chunks: ['news/sport'],
// access in template is very ugly: `htmlWebpackPlugin.options.data.title`,
// using `pug-plugin`, the variable in Pug is accessible w/o any scope: `title`
// (of cause, in `pug-plugin` you can define a variable scope, if you want)
data: { title: 'Sport news' }
}),
// ... Do you have the joy of adding yet one page using the HtmlWebpackPlugin?
// No? Then try to use the `pug-plugin`.
// Yet one plugin to extract CSS and inject one into HTML.
new MiniCssExtractPlugin({
// CSS output filename defined in another place, here
filename: 'css/[name].[contenthash:8].css',
}),
],
module: {
rules: [
// requires to define the pug loader
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
},
{
test: /\.(s?css|sass)$/,
// requires additional MiniCssExtractPlugin loader
use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader'],
},
{
test: /\.(png|jpe?g|ico)/,
type: 'asset/resource',
generator: {
filename: 'img/[name].[hash:8][ext]',
},
},
],
},
};
Why do many developers switch from Webpack to other bundlers? One of the reasons they cite is the complex configuration many different plugins and loaders for one simple thing - rendering an HTML page with assets.
The pug-plugin "changes the rule of the game". Just one plugin replaces the functionality of many plugins and loaders and makes configuration very simple and clear.
A Pug template can be used in JavaScript code as template function with custom data.
Install the pug-loader
.
npm install @webdiscus/pug-loader --save-dev
Change your webpack.config.js according to the following minimal configuration:
const path = require('path');
module.exports = {
output: {
path: path.join(__dirname, 'public/'),
publicPath: '/', // must be defined any path, `auto` is not supported yet
},
entry: {
index: './src/index.js', // load a Pug template in JS
},
module: {
rules: [
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
},
],
},
};
Load a Pug template in JavaScript. Optional you can pass any data into generated template function.
./src/index.js
const tmpl = require('template.pug');
const html = tmpl({
myVar: 'value',
});
See original description of options
Type: string
Default: /
The root directory of all absolute inclusion.
Type: string
Default: html
Specifies the type of document. See available doctypes.
Type: boolean
Default: false
Use the self
as namespace for the local variables in template. It will speed up the compilation, but for access to variable, e.g. myVariable
, you must write self.myVariable
.
Type: Array<string>
Default: []
Add a list of global names to make accessible in templates.
Type: object
Default: undefined
Filters let to use other languages in Pug templates.
You can add your own custom filters to Pug.
See the build-in filters.
Type: Array<Object>
Default: []
Plugins allow to manipulate Pug tags, template content in compile process.
How it works see in source of pug.
Type: boolean
Default: false
Includes the function source in the compiled template to improve error reporting.
Type: boolean
Default: false
This option is deprecated by pugjs and always is false
. Don't use it.
Warning
Since the version
2.11.0
, themethod
option name is renamed intomode
.
Themethod
option is DEPRECATED.The
method
values are renamed:
pug-compile
=>compile
pug-render
=>render
The
method
option name and old values can be used until the next major version.
Type: string
Default: compile
Values:
compile
the Pug template compiles into a template function and in JavaScript can be called with variables to render into HTML at runtime.
The query parameter is?compile
. Can be used if the mode isrender
.
Use this mode, if the template have variables passed from JavaScript at runtime. see usagerender
the Pug template renders into HTML at compile time and exported as a string. All required resource will be processed by the webpack and separately included as added strings wrapped to a function.
The query parameter is?render
. Can be used if the mode iscompile
or is not defined in options.
Use this mode, if the template does not have variables passed from JavaScript at runtime. The mode generates the most compact and fastest code. see usagehtml
the template renders into a pure HTML string at compile time. The mode need an addition loader to handles the HTML.
Use this mode if the rendered HTML needs to be processed by additional loader, e.g. byhtml-loader
see usage
Asset resources such as
img(src=require('./image.jpeg'))
are handled at compile time by the webpack using asset/resource.
Type: Boolean
Default: false
Enable / disable ESM syntax in generated JS modules.
Values:
true
Thepug-loader
generates JS modules with the ESM syntax.
For example:import html from 'template.pug';
.
For smaller and faster JS code, it is recommended to use this mode.false
defaults. Thepug-loader
generates JS modules with the CommonJS modules syntax.
For example,const html = require('template.pug')
.
The default value isfalse
for compatibility with the JS modules that is generated by the original pug-loader.
Note: The option
esModule
is irrelevant for thehtml
mode, because it returns a pure HTML string.
💡 For generates smaller and faster template function, it is recommended to use following options:
{
mode: 'render',
esModule: true,
}
Type: Object
Default: {}
The custom data will be passed in all Pug templates, it can be useful by pass global data.
⚠️ Limitation with thecompile
mode.
A string representing the source code of the function is limited by thefunction.toString()
, see examples.
For native work of the function passed via thedata
loader option, use therender
mode.
Type: Object
Default: undefined
Enable embedded Pug filters.
To enable a filter, add the following to the pug-loader options:
{
embedFilters: {
<FILTER_NAME> : <FILTER_OPTIONS> | <TRUE>,
}
}
Where <FILTER_NAME>
is the name of a built-in filter, the available filters see below.
The filter can have options <FILTER_OPTIONS>
as an object.
If the filter has no options, use true
as an option to enable the filter.
See the complete information on the pug filter site and in the sources.
Type: Array<RegExp|string>
Default: [ /\.(pug|jade|js.{0,2}|.?js|ts.?|md|txt)$/i ]
This option allows you to configure watching of individual resolved dependencies.
The default value enables watching of Pug, scripts, markdown, etc.
and ignores images, styles to avoid double processing via Webpack and via Pug's ist own compiler.
In some cases, you may want to use one SCSS file for styling
and include another SCSS file with a Pug filter for code syntax highlighting.
The first SCSS file is watched via Webpack, but changes in the second will be ignored.
For example, we want to watch for changes in all source examples such as main.c
, colors.scss
, etc. from the /code-samples/
folder,
to do this, add to the watchFiles
option:
{
watchFiles: [
/\\/code-samples\\/.+$/,
]
}
For watching of a file, add full path, for example:
{
watchFiles: [
path.join(__dirname, './src/config.yml'),
]
}
Note: Default value of
watchFiles
will be extends, not overridden.
This mode is used by default.
In JavaScript the required template will be compiled into template function.
In webpack config add to module.rules
:
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
mode: 'compile' // default mode `compile` can be omitted
}
}
In JavaScript, the result of require() is a template function. Call the template function with some variables to render it to HTML.
const tmpl = require('template.pug');
const html = tmpl({ key: 'value' }); // the HTML string
To render the Pug direct into HTML, use the query parameter ?render
.
// compile into template function, because loader option 'mode' defaults is 'compile'
const tmpl = require('template.pug');
const html = tmpl({ key: 'value' });
// render the Pug file into HTML, using the parameter 'render'
const html2 = require('template2.pug?render');
Note: If the query parameter
render
is set, then will be used rendering for this template, independent of the loader optionmode
. Variables passed in template with moderender
will be used at compile time.
This mode will render the Pug into HTML at compile time.
In webpack config add to module.rules
:
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
mode: 'render',
},
}
In JavaScript the result of require() is an HTML string.
const html = require('template.pug'); // the HTML string
To generate a template function for passing the data in Pug at realtime, use the query parameter ?compile
.
// render into HTML, because loader option 'mode' is 'render'
const html = require('template.pug');
// compile into template function, using the parameter 'compile'
const tmpl2 = require('template2.pug?compile');
const html2 = tmpl2({ ... });
This mode will render the Pug to pure HTML and should be used with an additional loader to handle HTML.
In webpack config add to module.rules
:
{
test: /\.pug$/,
use: [
{
loader: 'html-loader',
options: {
esModule: false, // allow to use the require() for load a template in JavaScript
},
},
{
loader: '@webdiscus/pug-loader',
options: {
mode: 'html',
},
},
],
}
In JavaScript the result of require() is an HTML string:
const html = require('template.pug'); // the HTML string
The goal of built-in filters is to use most useful lightweight filters without installation.
The built-in filters are custom filters that are collected in one place.
These filters can be simply enabled via an option.
See the complete information on the pug filter site and in the sources.
Defaults all built-in filters are disabled. Enable only filters used in your Pug templates.
The filter replaces reserved HTML characters with their corresponding HTML entities to display these characters as text.
Filter options: none
.
Enable the filter:
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
// enable built-in filters
embedFilters: {
escape: true, // enable the :escape filter
},
},
},
Using the :escape
filter in pug:
pre: code.language-html
:escape
<h1>Header</h1>
Generated HTML:
<pre>
<code class="language-html">
<h1>Header</h1>
</code>
</pre>
Inline syntax:
p.
The #[:escape <html>] element is the root element.<br>
Inside the #[:escape <html>] element there is a #[:escape <body>] element.
Generated HTML:
<p>The <html> element is the root element.<br>
Inside the <html> element there is a <body> element.</p>
For more information and examples, see the :escape site.
The filter wraps a content with the <code>
tag.
Filter options:
className {string}
The class name of thecode
tag. For example, theprismjs
use thelanguage-*
as class name in<code>
for styling this tag.
Enable the filter:
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
// enable built-in filters
embedFilters: {
// enable the :code filter
code: {
className: 'language-', // class name of `<code>` tag, needed for `prismjs` theme
},
},
},
},
Usage examples:
Pug: #[:code function() { return true }]
Display: function() { return true }
Pug: #[:code:escape <div>]
Display: <div>
Pug: #[:code:highlight(html) <div class="container">content</div>]
Display highlighted code: <div class="container">content</div>
For more information and examples, see the :code site.
The filter highlights code syntax.
Filter options:
verbose {boolean}
Enable output process info in console.use {string}
The name of a highlighting npm module. The module must be installed. Currently, is supported the prismjs only.
Enable the filter:
{
embedFilters: {
highlight: {
verbose: true,
use: 'prismjs',
},
},
}
Usage example:
pre.language-: code
:highlight(html)
<!-- Comment -->
<h1>Header</h1>
<p>Text</p>
For more information and examples, see the :highlight site.
The filter transform markdown to HTML and highlights code syntax.
The :markdown
filter require the markdown-it and prismjs modules:
npm install -D markdown-it prismjs
Enable the filter:
{
test: /.pug$/,
loader: '@webdiscus/pug-loader',
options: {
// enable built-in filters
embedFilters: {
// enable :markdown filter
markdown: {
// enable highlighting in markdown
highlight: {
verbose: true,
use: 'prismjs',
},
},
},
},
},
The highlight
options:
verbose {boolean}
Enable output process info in console. Use it in development mode only. Defaults is false.use {string}
The name of a highlighting npm module. The module must be installed. Currently, is supported the prismjs only.
Usage example:
:markdown
_HTML_
```html
<!-- Comment -->
<div class="container">
<p>Paragraph</p>
</div>
```
_JavaScript_
```js
const arr = [1, 2, 'banana'];
```
Display highlighted code blocks:
HTML
<!-- Comment --> <div class="container"> <p>Paragraph</p> </div>JavaScript
const arr = [1, 2, 'banana'];
For more information and examples, see the :markdown site.
By default, the Pug file is compiled as template function, into which can be passed an object with template variables.
const tmpl = require('template.pug');
const html = tmpl({
myVar: 'value',
foo: 'bar'
});
But how pass variables in template which is rendered into HTML?
Variables can be passed with query parameters.
const html = require('template.pug?myVar=value&foo=bar');
or as a JSON object:
const html = require('template.pug?' + JSON.stringify({ myVar: 'value', foo: 'bar' }));
Use variables myVar
and foo
in Pug template.
div The value of "myVar": #{myVar}
div The value of "foo": #{foo}
Usage of query parameters is legal and official documented feature of webpack loader.
Pass myData
object via query.
entry: {
about: './src/pages/about.pug?myData=' + JSON.stringify({ title: 'About', options: { uuid: 'abc123' } })
}
Use the object myData
in Pug template.
html
head
title= myData.title
body
div UUID: #{myData.options.uuid}
To pass global data to all Pug templates, add the loader options data
as any object.
module.exports = {
module: {
rules: [
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
data: {
htmlLang: 'en-EN',
getKeywords: () => {
const keywords = ['webpack', 'pug', 'loader'];
return keywords.join(',');
}
}
}
},
],
},
};
Use the custom data and function in pug.
html(lang=htmlLang)
head
meta(name="keywords" content=getKeywords())
body
The user data can be passed into Pug template with two ways:
- via HtmlWebpackPlugin options
- via query parameters of template file
module.exports = {
plugins: [
new HtmlWebpackPlugin({
title: 'The some page', // avaliable in Pug as `htmlWebpackPlugin.options.title`
template: path.join(__dirname, 'src/index.pug?' + JSON.stringify({ myVar: 'value' })), // avaliable as `myVar`
filename: 'index.html',
}),
],
module: {
rules: [
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
},
],
},
};
Use the passed variables htmlWebpackPlugin.options
and myVar
in Pug template:
html
head
title= htmlWebpackPlugin.options.title
body
div= myVar
You can load data directly in pug.
data.json
[
{ "id": 1, "name": "abc" },
{ "id": 2, "name": "xyz" }
]
Require the JSON file in pug.
- var myData = require('./data.json')
each item in myData
div #{item.id} #{item.name}
To handle resources in Pug use the require()
function:
img(src=require('./path/to/images/logo.png'))
For images, add the following rule to the webpack module:
module.exports = {
module: {
rules: [
{
test: /\.(png|jpg|jpeg|svg|ico)/,
type: 'asset/resource',
generator: {
filename: 'assets/images/[name].[hash:8][ext]',
},
},
]
},
};
For fonts, add the following rule to the webpack module:
module.exports = {
module: {
rules: [
{
test: /\.(woff2|woff|ttf|svg|eot)/,
type: 'asset/resource',
generator: {
filename: 'assets/fonts/[name][ext]',
},
},
]
},
};
More information about asset-modules see here.
Example of dynamic interpolation of image src in pug:
- files = ['image1.jpeg', 'image2.jpeg', 'image3.jpeg']
each file in files
img(src=require(`./path/to/${file})`)
Recommended to use the Webpack alias to avoid relative paths in Pug.
For example, use the alias Images
as path to images:
module.exports = {
resolve: {
alias: {
Images: path.join(__dirname, 'src/assets/images/'),
},
}
};
The alias may be used with prefixes ~
or @
.
For example, all following aliases resolves the same path:
img(src=require('Images/logo.png'))
img(src=require('~Images/logo.png'))
img(src=require('@Images/logo.png'))
Using TypeScript
you can define an alias in tsconfig.json
.
But for performance is recommended to use the Webpack alias.
For example, add to tsconfig.json
an alias to the paths
option:
tsconfig.json
{
"compilerOptions": {
"paths": {
"Images/*": ["assets/images/*"]
}
}
}
Warning
The
compile
mode can resolve the filename as a string only and the filename can't be interpolated.img(src=require('Images/logo.png')) // It works. - const file = 'logo.png' img(src=require('Images/' + file)) // ERROR: Can't be resolved with 'compile' mode.
You can use the Webpack context
for a short path in Pug.
Define in Webpack config the context
as path to sources:
module.exports = {
context: path.resolve(__dirname, 'src'),
};
For example, your images are under the path PROJECT_PATH/src/assets/images/
,
then using the context
you can use the root path (relative by context) anywhere:
img(src=require('/assets/images/logo.png'))
Note
You can use the
basedir
option of pug-loader for same effect:module.exports = { module: { rules: [ { test: /\.pug$/, loader: '@webdiscus/pug-loader', options: { basedir: path.resolve(__dirname, 'src') }, }, ], }, };
The file in the current- or subdirectory MUST
start with ./
:
img(src=require('./path/to/logo.png'))
The file in the parent directory MUST
start with ../
:
img(src=require('../images/logo.png'))
Warning
Following relative path will be resolved with
render
andhtml
modes, butNOT
withcompile
mode:img(src=require('../../images/logo.png'))This is an interpolation limitation in Webpack.
You can use the filename as a variable.
Usage examples work with all modes:
- const file = 'logo.png'
img(src=require('./images/' + file))
img(src=require(`./images/${file}`))
img(src=require('../images/' + file))
img(src=require('Images/' + file)) // 'Images' is webpack alias
img(src=require(`Images/${file}`)
Warning
Limitation using the
compile
mode:
the variableMUST NOT
contain a path, only a filename, because is interpolated at compile time.
For example, the 'compile' mode can't resolve following:- var file = '../images/logo.png' img(src=require(file))
Using a variable with render
or html
mode, the variable MAY
contain a path, because is resolved at runtime.
Following example work only with render
or html
mode:
- const file = '../relative/path/to/logo.png'
img(src=require(file))
img(src=require('Images/' + file))
In current directory, the filename MUST
start with ./
:
- const file = './logo.png'
img(src=require(file))
Install:
npm i --save-dev @webdiscus/pug-loader pug-plugin-ng
In pug-loader can be used the optional pug-plugin-ng to allow unquoted syntax of Angular:

Create the file webpack.config.js
in root directory of angular project:
module.exports = {
module: {
rules: [
{
test: /\.pug$/,
loader: '@webdiscus/pug-loader',
options: {
mode: 'render',
doctype: 'html',
plugins: [require('pug-plugin-ng')],
},
},
],
},
};
Bind the file webpack.config.js
in the Angular config angular.json
:
{
// ...
"projects": {
// ...
"architect": {
"build": {
// replace architect.build.builder with this value:
"builder": "@angular-builders/custom-webpack:browser",
// add the options:
"options": {
"aot": true,
"customWebpackConfig": {
"path": "./webpack.config.js" // the path to webpack.config.js
},
// ...
},
// ...
},
"serve": {
// replace architect.serve.builder with this value:
"builder": "@angular-builders/custom-webpack:dev-server",
"options": {
"browserTarget": "<app-name>:build"
},
// ...
},
// ...
},
},
},
In a component file, e.g. ./src/app/app.component.ts
set the templateUrl
with Pug file:
import { Component } from '@angular/core';
// the variable `description` will be passed into Pug template via resource query
const templateVars = '{"description": "Use Pug template with Angular."}';
@Component({
selector: 'app-root',
styleUrls: ['./app.component.css'],
templateUrl: './app.component.pug?' + templateVars,
})
export class AppComponent {
title = 'ng-app';
}
Create a Pug template, e.g. ./src/app/app.component.pug
:
h1 Hello Pug!
p Description: #{description}
See the complete source of the example.
Install:
npm i --save-dev @webdiscus/pug-loader
Change your vue.config.js
according to the following minimal configuration:
const { defineConfig } = require('@vue/cli-service');
// additional pug-loader options,
// e.g. to enable pug filters such as `:highlight`, `:markdown`, etc.
// see https://github.com/webdiscus/pug-loader#options
const pugLoaderOptions = {
};
module.exports = defineConfig({
transpileDependencies: true,
chainWebpack: (config) => {
// clear all existing pug loaders
const pugRule = config.module.rule('pug');
pugRule.uses.clear();
pugRule.oneOfs.clear();
// exclude `pug-loader` from the witchery of the baggy `thread-loader` that is used in production mode
const jsRule = config.module.rule('js');
jsRule.exclude.add(/pug-loader/);
},
configureWebpack: {
module: {
rules: [
{
test: /\.pug$/,
oneOf: [
// allow <template lang="pug"> in Vue components
{
resourceQuery: /^\?vue/u,
loader: '@webdiscus/pug-loader',
options: {
mode: 'html', // render Pug into pure HTML string
...pugLoaderOptions,
},
},
// allow import of Pug in JavaScript
{
loader: '@webdiscus/pug-loader',
options: {
mode: 'compile', // compile Pug into template function
...pugLoaderOptions,
},
},
],
},
],
},
},
});
For additional information see please the discussion: How to configure the plugin for both Vue and non-Vue usage?
Using Pug in Vue template
<template lang='pug'>
h1 Hello Pug!
p Use the '@webdiscus/pug-loader'
</template>
Note
You can use an indent for Pug code in Vue template.
Using Pug in JavaScript
App.vue
<template>
<div v-html='demo'></div>
</template>
<script>
// import Pug as template function
import demoTmpl from './views/demo.pug';
// define custom data used in Pug template
const locals = { colors: ['red', 'green', 'blue'] };
// pass custom data in Pug template
const demoHtml = demoTmpl(locals);
export default {
name: 'App',
data() {
return {
demo: demoHtml
}
}
}
</script>
demo.pug
each color in colors
div(style=`color: ${color}`) #{color}
Note: The
colors
is external variable passed from App.vue.
img(srcset=`${require('./image1.jpeg')} 320w, ${require('./image2.jpeg')} 640w` src=require('./image.jpeg'))
output
<img srcset="/assets/image1.f78b30f4.jpeg 320w, /assets/image2.f78b30f4.jpeg 640w" src="/assets/image.f78b30f4.jpeg">
Use the require()
for CommonJS files in Pug templates.
The JS module say-hello.js
module.exports = function(name) {
return `Hello ${name}!`;
}
Use the module sayHello
in Pug template.
- var sayHello = require('./say-hello')
h1 #{sayHello('pug')}
npm run test
will run the unit and integration tests.
npm run test:coverage
will run the tests with coverage.
