+
+A small utility for generating consistent warning objects across your codebase.
+It also exposes a utility for emitting those warnings, guaranteeing that they are issued only once (unless configured otherwise).
+
+_This module is used by the [Fastify](https://fastify.dev) framework and it was called `fastify-warning` prior to version 1.0.0._
+
+### Install
+
+```
+npm i process-warning
+```
+
+### Usage
+
+The module exports two builder functions for creating warnings.
+
+```js
+const {
+  createWarning,
+  createDeprecation
+} = require('process-warning')
+
+const warning = createWarning({
+  name: 'ExampleWarning',
+  code: 'EXP_WRN_001',
+  message: 'Hello %s',
+  unlimited: true
+})
+warning('world')
+```
+
+#### Methods
+
+##### `createWarning({ name, code, message[, unlimited] })`
+
+- `name` (`string`, required) - The error name, you can access it later with
+`error.name`. For consistency, we recommend prefixing module error names
+with `{YourModule}Warning`
+- `code` (`string`, required) - The warning code, you can access it later with
+`error.code`. For consistency, we recommend prefixing plugin error codes with
+`{ThreeLetterModuleName}_`, e.g. `FST_`. NOTE: codes should be all uppercase.
+- `message` (`string`, required) - The warning message. You can also use
+interpolated strings for formatting the message.
+- `options` (`object`, optional) - Optional options with the following
+properties:
+  + `unlimited` (`boolean`, optional) - Should the warning be emitted more than
+  once? Defaults to `false`.
+
+
+##### `createDeprecation({code, message[, options]})`
+
+This is a wrapper for `createWarning`. It is equivalent to invoking
+`createWarning` with the `name` parameter set to "DeprecationWarning".
+
+Deprecation warnings have extended support for the Node.js CLI options:
+`--throw-deprecation`, `--no-deprecation`, and `--trace-deprecation`.
+
+##### `warning([, a [, b [, c]]])`
+
+The returned `warning` function can used for emitting warnings.
+A warning is guaranteed to be emitted at least once.
+
+- `[, a [, b [, c]]]` (`any`, optional) - Parameters for string interpolation.
+
+```js
+const { createWarning } = require('process-warning')
+const FST_ERROR_CODE = createWarning({ name: 'MyAppWarning', code: 'FST_ERROR_CODE', message: 'message' })
+FST_ERROR_CODE()
+```
+
+How to use an interpolated string:
+```js
+const { createWarning } = require('process-warning')
+const FST_ERROR_CODE = createWarning({ name: 'MyAppWarning', code: 'FST_ERROR_CODE', message: 'Hello %s'})
+FST_ERROR_CODE('world')
+```
+
+The `warning` object has methods and properties for managing the warning's state. Useful for testing.
+```js
+const { createWarning } = require('process-warning')
+const FST_ERROR_CODE = createWarning({ name: 'MyAppWarning', code: 'FST_ERROR_CODE', message: 'Hello %s'})
+console.log(FST_ERROR_CODE.emitted) // false
+FST_ERROR_CODE('world')
+console.log(FST_ERROR_CODE.emitted) // true
+
+const FST_ERROR_CODE_2 = createWarning('MyAppWarning', 'FST_ERROR_CODE_2', 'Hello %s')
+FST_ERROR_CODE_2.emitted = true
+FST_ERROR_CODE_2('world') // will not be emitted because it is not unlimited
+```
+
+How to use an unlimited warning:
+```js
+const { createWarning } = require('process-warning')
+const FST_ERROR_CODE = createWarning({ name: 'MyAppWarning', code: 'FST_ERROR_CODE', message: 'Hello %s', unlimited: true })
+FST_ERROR_CODE('world') // will be emitted
+FST_ERROR_CODE('world') // will be emitted again
+```
+
+#### Suppressing warnings
+
+It is possible to suppress warnings by utilizing one of node's built-in warning suppression mechanisms.
+
+Warnings can be suppressed:
+
+- by setting the `NODE_NO_WARNINGS` environment variable to `1`
+- by passing the `--no-warnings` flag to the node process
+- by setting '--no-warnings' in the `NODE_OPTIONS` environment variable
+
+For more information see [node's documentation](https://nodejs.org/api/cli.html).
