eslint-plugin-file-header

Rule to check if file contains specified comment.

Installation

yarn add -D eslint-plugin-file-header

Example:

module.exports = {
  plugins: ["file-header"],
  rules: {
    "file-header/file-header": [
      "error",
      [
        "This Source Code Form is subject to the terms of the Mozilla Public",
        "License, v. 2.0. If a copy of the MPL was not distributed with this",
        "file, You can obtain one at <http://mozilla.org/MPL/2.0/>."
      ],
      "block",
      ["-\\*-(.*)-\\*-", "eslint(.*)", "vim(.*)"]
    ]
  }
};

Options:

1. header - array of lines of the header (without comment tags).
2. commentType - either block, line or null. Plugin will use this option to search for headers and to fix missing header. If commentType is null rule will use both comment types to check for headers (and line type will be used when fixing).
3. ignoredComments - array of patterns that this rule will ignore (they won't be replaced by the rule and new header will be inserted after last ignoredComment if any).

Hardcoded rules:

• Header must not be intended.
• Header must start in the 6 first lines of file.
