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.

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 v3.2.0, we introduced "jsonc" parser which adds trailing 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 .prettierrc file

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

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

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

Add preferUnplugged: true to package.json (#​15169 by @​fisker and @​so1ve)

Prettier v3 uses dynamic imports, user will need to unplug Prettier when Yarn's PnP mode is enabled, add preferUnplugged: true to package.json, so Yarn will install Prettier as unplug by default.

Support shared config that forbids require() (#​15233 by @​fisker)

If an external shared config package is used, and the package exports don't have require or default export.
