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.

v5.1.0

Compare Source

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.

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
@​(foo`tagged template`)
class X {}

// Prettier 3.3.2
@​foo`tagged template`
class X {}

// Prettier 3.3.3
@​(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:

@​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.

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

})
export class AppComponent {}

// Prettier 3.2.4

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"
      }
    }
  ]
}
