Changed: All the [formatting rules that were deprecated in ESLint 8.53.0][deprecated-8.53.0] are now excluded if you set the ESLINT_CONFIG_PRETTIER_NO_DEPRECATED environment variable.

`v5.2.1`

Patch Changes

#668 ac036cc Thanks @OrlovAlexei! - build(deps): Bump synckit from 0.8.6 to 0.9.1

`v5.1.3`

Patch Changes

#629 985b33c Thanks @JounQin! - chore: add package.json into exports map

`v5.1.2`

Patch Changes

#623 8210e44 Thanks @BPScott! - Add exports mapping to package.json, to allow import eslintPluginRecommended from 'eslint-plugin-prettier/recommended' to work as expected.

Strictly speaking this is a breaking change as it removes the ability for people to import from "eslint-plugin-prettier/eslint-plugin-prettier.js" and "eslint-plugin-prettier/recommended.js" but the former was never recommended in the first place and the latter has only been available for a few days.
#621 2b09e7f Thanks @JounQin! - feat: support parsing markdown via eslint-mdx natively

`v5.1.1`

Patch Changes

#619 b5c0dc5 Thanks @JounQin! - chore: skip formatting inline scripts in pug files

`v5.1.0`

Minor Changes

#616 3856413 Thanks @BPScott! - Add recommended config for the flat config format.

If you are using flat config, import the recommended config from eslint-plugin-prettier/recommended. Like the legacy format recommended config, this automatically includes the contents of eslint-config-prettier.
```
// eslint.config.js
const eslintPluginPrettierRecommended = require('eslint-plugin-prettier/recommended');

module.exports = [
  // Any other config imports go at the top
  eslintPluginPrettierRecommended,
];
```

Patch Changes

#614 5270877 Thanks @BPScott! - Add meta block to plugin. This improves debugging and cachebusting when using the new flat config
#603 a63a570 Thanks @filiptammergard! - fix: specify eslint-config-prettier as peer dependency

It's already added to peerDependenciesMeta as optional, which means it should also be specified in peerDependencies.

`v3.4.1`

Remove unnecessary parentheses around assignment in `v-on` (#16887 by @fisker)

<!-- Input -->
<template>
  <button @&#8203;click="foo += 2">Click</button>
</template>

<!-- Prettier 3.4.0 -->
<template>
  <button @&#8203;click="(foo += 2)">Click</button>
</template>

<!-- Prettier 3.4.1 -->
<template>
  <button @&#8203;click="foo += 2">Click</button>
</template>

`v3.4.0`

`v3.3.3`

Add parentheses for nullish coalescing in ternary (#16391 by @cdignam-segment)

This change adds clarity to operator precedence.

// Input
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.2
foo ? bar ?? foo : baz;
foo ?? bar ? a : b;
a ? b : foo ?? bar;

// Prettier 3.3.3
foo ? (bar ?? foo) : baz;
(foo ?? bar) ? a : b;
a ? b : (foo ?? bar);

Add parentheses for decorator expressions (#16458 by @y-schneider)

Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.

// Input
@&#8203;(foo`tagged template`)
class X {}

// Prettier 3.3.2
@&#8203;foo`tagged template`
class X {}

// Prettier 3.3.3
@&#8203;(foo`tagged template`)
class X {}

Support `@let` declaration syntax (#16474 by @sosukesuzuki)

Adds support for Angular v18 @let declaration syntax.

Please see the following code example. The @let declaration allows you to define local variables within the template:

@&#8203;let name = 'Frodo';

<h1>Dashboard for {{name}}</h1>
Hello, {{name}}

For more details, please refer to the excellent blog post by the Angular Team: Introducing @let in Angular.

We also appreciate the Angular Team for kindly answering our questions to implement this feature.

`v3.3.2`

Fix handlebars path expressions starts with `@` (#16358 by @Princeyadav05)

{{! Input }}
<div>{{@&#8203;x.y.z}}</div>

{{! Prettier 3.3.1 }}
<div>{{@&#8203;x}}</div>

{{! Prettier 3.3.2 }}
<div>{{@&#8203;x.y.z}}</div>

<!-- Input -->
---yaml
title: Hello
slug: home
---

<!-- Prettier 3.3.0 -->
---
title: Hello
slug: home
---

<!-- Prettier 3.3.1 -->
---yaml
title: Hello

Avoid line breaks in import attributes (#16349 by @fisker)

// Input
import something from "./some-very-very-very-very-very-very-very-very-long-path.json" with { type: "json" };

// Prettier 3.3.0
import something from "./some-very-very-very-very-very-very-very-very-long-path.json" with { type:
  "json" };

// Prettier 3.3.1
import something from "./some-very-very-very-very-very-very-very-very-long-path.json" with { type: "json" };

`v3.3.0`

`v3.2.5`

Support Angular inline styles as single template literal (#15968 by @sosukesuzuki)

Angular v17 supports single string inline styles.

// Input
@&#8203;Component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.4
@&#8203;Component({
  template: `<div>...</div>`,
  styles: `h1 { color: blue; }`,
})
export class AppComponent {}

// Prettier 3.2.5
@&#8203;Component({
  template: `<div>...</div>`,
  styles: `
    h1 {
      color: blue;
    }
  `,
})
export class AppComponent {}

Unexpected embedded formatting for Angular template (#15969 by @JounQin)

Computed template should not be considered as Angular component template

// Input
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.4
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{ hello }}</h1>`,
})
export class AppComponent {}

// Prettier 3.2.5
const template = "foobar";

@&#8203;Component({
  [template]: `<h1>{{       hello }}</h1>`,
})
export class AppComponent {}

Use `"json"` parser for `tsconfig.json` by default (#16012 by @sosukesuzuki)

In v2.3.0, we introduced "jsonc" parser which adds trialing comma by default.

When adding a new parser we also define how it will be used based on the linguist-languages data.

tsconfig.json is a special file used by TypeScript, it uses .json file extension, but it actually uses the JSON with Comments syntax. However, we found that there are many third-party tools not recognize it correctly because of the confusing .json file extension.

We decide to treat it as a JSON file for now to avoid the extra configuration step.

To keep using the "jsonc" parser for your tsconfig.json files, add the following to your .pretterrc file

{
  "overrides": [
    {
      "files": ["tsconfig.json", "jsconfig.json"],
      "options": {
        "parser": "jsonc"
      }
    }
  ]
}

`v3.2.4`

Fix incorrect parser inference (#15947 by @fisker)

Files like .eslintrc.json were incorrectly formatted as JSONC files.

// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }

// Prettier 3.2.4
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "json" }

`v3.2.3`

Throw errors for invalid code (#15881 by @fisker, @Josh-Cena, @auvred)

// Input
1++;

// Prettier 3.2.2
1++;

// Prettier 3.2.3
SyntaxError: Invalid left-hand side expression in unary operation (1:1)
> 1 | 1++;
    | ^

// Input
try {} catch (error = 1){}

// Prettier 3.2.2
try {
} catch (error) {}

// Prettier 3.2.3
SyntaxError: Catch clause variable cannot have an initializer. (1:23)
> 1 | try {} catch (error = 1){}
    |                       ^

Fix parser inference (#15927 by @fisker)

// Prettier 3.2.2
prettier --file-info tsconfig.json
{ "ignored": false, "inferredParser": "json" }

// Prettier 3.2.3
prettier --file-info tsconfig.json
{ "ignored": false, "inferredParser": "jsonc" }

`v3.2.2`

Fix crash when parsing template literal CSS in a JSX style tag using a spread attribute (#15896 by @eelco)

For example this code would crash before:

<style {...spread}>{`.{}`}</style>

Fix formatting error on optional call expression and member chain (#15920 by @sosukesuzuki)

// Input
a(() => {}, c?.d());

// Prettier 3.2.1
TypeError: Cannot read properties of undefined (reading 'type')

// Prettier 3.2.2
a(() => {}, c?.d());

`v3.2.1`

Fix formatting error on member chain (#15915 by @sosukesuzuki)

// Input
test().test2().test2(thing?.something);

// Prettier 3.2.0
TypeError: Cannot read properties of undefined (reading 'type')

// Prettier 3.2.1
test().test2().test2(thing?.something);

`v3.2.0`

`v3.1.1`

Fix config file search (#15363 by @fisker)

Previously, we start search for config files from the filePath as a directory, if it happened to be a directory and contains config file, it will be used by mistake.

├─ .prettierrc
└─ test.js         (A directory)
  └─ .prettierrc

// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/test.js/.prettierrc

// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// <CWD>/.prettierrc

Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` (#15533 by @sanmai-NL)

Since Prettier v3, we stopped following symbolic links, however in some use cases, the symbolic link patterns can't be filtered out, and there is no way to prevent Prettier from throwing errors.

In Prettier 3.1.1, you can use --no-error-on-unmatched-pattern to simply skip symbolic links.

Consistently use tabs in ternaries when `useTabs` is `true` (#15662 by @auvred)

// Input
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.0
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
	  ? ddddddddddddddd
	  : eeeeeeeeeeeeeee
	    ? fffffffffffffff
	    : gggggggggggggggg;

// Prettier 3.1.1
aaaaaaaaaaaaaaa
	? bbbbbbbbbbbbbbbbbb
	: ccccccccccccccc
		? ddddddddddddddd
		: eeeeeeeeeeeeeee
			? fffffffffffffff
			: gggggggggggggggg;

Improve config file search (#15663 by @fisker)

The Prettier config file search performance has been improved by more effective cache strategy.

Fix unstable and ugly formatting for comments in destructuring patterns (#15708 by @sosukesuzuki)

// Input
const {
  foo,
  // bar
  // baz
}: Foo = expr;

// Prettier 3.1.0
const {
  foo1,
} // bar
// baz
: Foo = expr;

// Prettier 3.1.0 second output
const {
  foo1, // bar
} // baz
: Foo = expr;

// Prettier 3.1.1
const {
  foo1,
  // bar
  // baz
}: Foo = expr;

Support "Import Attributes" (#15718 by @fisker)

TypeScript 5.3 supports the latest updates to the import attributes proposal.

import something from "./something.json" with { type: "json" };

Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd (#15750 by @ExplodingCabbage)

The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by @ds300. However, Prettier's documentation (including the CLI --help text) continued to claim otherwise, falsely. The documentation is now fixed.

Keep curly braces and `from` keyword in empty `import` statements (#15756 by @fisker)

// Input
import { } from 'foo';
import { /* comment */ } from 'bar';

// Prettier 3.1.0
import {} from "foo";
import /* comment */ "bar";

// Prettier 3.1.1
import {} from "foo";
import {} from /* comment */ "bar";

Keep empty import attributes and assertions (#15757 by @fisker)

// Input
import foo from "foo" with {};
import bar from "bar" assert {};

// Prettier 3.1.0
import foo from "foo";
import bar from "bar";

// Prettier 3.1.1
import foo from "foo" with {};
import bar from "bar" assert {};
