# Deprecated APIs
<!--introduced_in=v7.7.0-->
<!-- type=misc -->
Node.js APIs might be deprecated for any of the following reasons:
* Use of the API is unsafe.
* An improved alternative API is available.
* Breaking changes to the API are expected in a future major release.
Node.js uses three kinds of Deprecations:
* Documentation-only
* Runtime
* End-of-Life
A Documentation-only deprecation is one that is expressed only within the
Node.js API docs. These generate no side-effects while running Node.js.
Some Documentation-only deprecations trigger a runtime warning when launched
with [`--pending-deprecation`][] flag (or its alternative,
`NODE_PENDING_DEPRECATION=1` environment variable), similarly to Runtime
deprecations below. Documentation-only deprecations that support that flag
are explicitly labeled as such in the
[list of Deprecated APIs](#list-of-deprecated-apis).
A Runtime deprecation will, by default, generate a process warning that will
be printed to `stderr` the first time the deprecated API is used. When the
[`--throw-deprecation`][] command-line flag is used, a Runtime deprecation will
cause an error to be thrown.
An End-of-Life deprecation is used when functionality is or will soon be removed
from Node.js.
## Revoking deprecations
Occasionally, the deprecation of an API might be reversed. In such situations,
this document will be updated with information relevant to the decision.
However, the deprecation identifier will not be modified.
## List of deprecated APIs
### DEP0001: `http.OutgoingMessage.prototype.flush`
<!-- YAML

The `_linklist` module is deprecated. Please use a userland alternative.
### DEP0003: `_writableState.buffer`
<!-- YAML

description: Runtime deprecation.
-->
Type: End-of-Life
The `_writableState.buffer` has been removed. Use `_writableState.getBuffer()`
instead.
### DEP0004: `CryptoStream.prototype.readyState`
<!-- YAML
changes:
- version: v10.0.0
pr-url: https://github.com/nodejs/node/pull/17882
description: End-of-Life.

commit: 9c7f89bf56abd37a796fea621ad2e47dd33d2b82
description: Documentation-only deprecation.
-->
Type: End-of-Life
The `CryptoStream.prototype.readyState` property was removed.
### DEP0005: `Buffer()` constructor
<!-- YAML
changes:
- version: v10.0.0
pr-url: https://github.com/nodejs/node/pull/19524
description: Runtime deprecation.
- version: v6.12.0
pr-url: https://github.com/nodejs/node/pull/10116
description: A deprecation code has been assigned.
- version: v6.0.0
pr-url: https://github.com/nodejs/node/pull/4682
description: Documentation-only deprecation.
-->
Type: Runtime (supports [`--pending-deprecation`][])
The `Buffer()` function and `new Buffer()` constructor are deprecated due to
API usability issues that can lead to accidental security issues.
As an alternative, use one of the following methods of constructing `Buffer`
objects:
* [`Buffer.alloc(size[, fill[, encoding]])`][alloc]: Create a `Buffer` with
_initialized_ memory.
* [`Buffer.allocUnsafe(size)`][alloc_unsafe_size]: Create a `Buffer` with
_uninitialized_ memory.
* [`Buffer.allocUnsafeSlow(size)`][]: Create a `Buffer` with _uninitialized_
memory.
* [`Buffer.from(array)`][]: Create a `Buffer` with a copy of `array`
* [`Buffer.from(arrayBuffer[, byteOffset[, length]])`][from_arraybuffer] -
Create a `Buffer` that wraps the given `arrayBuffer`.
* [`Buffer.from(buffer)`][]: Create a `Buffer` that copies `buffer`.
* [`Buffer.from(string[, encoding])`][from_string_encoding]: Create a `Buffer`
that copies `string`.
Without `--pending-deprecation`, runtime warnings occur only for code not in
`node_modules`. This means there will not be deprecation warnings for
`Buffer()` usage in dependencies. With `--pending-deprecation`, a runtime
warning results no matter where the `Buffer()` usage occurs.
### DEP0006: `child_process` `options.customFds`
<!-- YAML
changes:
- version: v12.0.0
pr-url: https://github.com/nodejs/node/pull/25279
description: End-of-Life.
- version:
- v6.12.0
- v4.8.6
pr-url: https://github.com/nodejs/node/pull/10116
description: A deprecation code has been assigned.
- version: v0.11.14
description: Runtime deprecation.
- version: v0.5.10
description: Documentation-only deprecation.
-->
Type: End-of-Life
Within the [`child_process`][] module's `spawn()`, `fork()`, and `exec()`
methods, the `options.customFds` option is deprecated. The `options.stdio`
option should be used instead.
### DEP0007: Replace `cluster` `worker.suicide` with `worker.exitedAfterDisconnect`
<!-- YAML
changes:
- version: v9.0.0
pr-url: https://github.com/nodejs/node/pull/13702
description: End-of-Life.
- version: v7.0.0
pr-url: https://github.com/nodejs/node/pull/3747

In an earlier version of the Node.js `cluster`, a boolean property with the name
`suicide` was added to the `Worker` object. The intent of this property was to
provide an indication of how and why the `Worker` instance exited. In Node.js
6.0.0, the old property was deprecated and replaced with a new
[`worker.exitedAfterDisconnect`][] property. The old property name did not
precisely describe the actual semantics and was unnecessarily emotion-laden.
### DEP0008: `require('constants')`

Type: Documentation-only
The `constants` module is deprecated. When requiring access to constants
relevant to specific Node.js builtin modules, developers should instead refer
to the `constants` property exposed by the relevant module. For instance,
`require('fs').constants` and `require('os').constants`.
### DEP0009: `crypto.pbkdf2` without digest

description: Runtime deprecation (for `digest === undefined`).
-->
Type: End-of-Life
Use of the [`crypto.pbkdf2()`][] API without specifying a digest was deprecated
in Node.js 6.0 because the method defaulted to using the non-recommended
`'SHA1'` digest. Previously, a deprecation warning was printed. Starting in
Node.js 8.0.0, calling `crypto.pbkdf2()` or `crypto.pbkdf2Sync()` with
`digest` set to `undefined` will throw a `TypeError`.
Beginning in Node.js v11.0.0, calling these functions with `digest` set to
`null` would print a deprecation warning to align with the behavior when `digest`
is `undefined`.
Now, however, passing either `undefined` or `null` will throw a `TypeError`.
