### [`v3.3.3`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333)
[Compare Source](https://togithub.com/prettier/prettier/compare/3.3.2...3.3.3)
[diff](https://togithub.com/prettier/prettier/compare/3.3.2...3.3.3)
##### Add parentheses for nullish coalescing in ternary ([#16391](https://togithub.com/prettier/prettier/pull/16391) by [@cdignam-segment](https://togithub.com/cdignam-segment))
This change adds clarity to operator precedence.
```js
// 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](https://togithub.com/prettier/prettier/pull/16458) by [@y-schneider](https://togithub.com/y-schneider))
Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5.
```ts
// 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](https://togithub.com/prettier/prettier/pull/16474) by [@sosukesuzuki](https://togithub.com/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:
```html
@let name = 'Frodo';
Dashboard for {{name}}
Hello, {{name}}
```
For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f).
We also appreciate the Angular Team for kindly answering our questions to implement this feature.

##### Support Angular inline styles as single template literal ([#15968](https://togithub.com/prettier/prettier/pull/15968) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
[Angular v17](https://blog.angular.io/introducing-angular-v17-4d7033312e4b) supports single string inline styles.
```ts
// Input
@Component({
template: `
`,
})
export class AppComponent {}
```
##### Use `"json"` parser for `tsconfig.json` by default ([#16012](https://togithub.com/prettier/prettier/pull/16012) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), 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`](https://www.npmjs.com/package/linguist-languages) data.
`tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_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
```json
{
"overrides": [
{
"files": ["tsconfig.json", "jsconfig.json"],
"options": {
"parser": "jsonc"
}
}
]
}
```
```
```

[Compare Source](https://togithub.com/prettier/prettier/compare/3.2.3...3.2.4)
[diff](https://togithub.com/prettier/prettier/compare/3.2.3...3.2.4)
##### Fix incorrect parser inference ([#15947](https://togithub.com/prettier/prettier/pull/15947) by [@fisker](https://togithub.com/fisker))
Files like `.eslintrc.json` were incorrectly formatted as JSONC files.
```jsx
// Input
prettier --file-info .eslintrc.json
{ "ignored": false, "inferredParser": "jsonc" }
// Prettier 3.2.4
prettier --file-info .eslintrc.json

[Compare Source](https://togithub.com/prettier/prettier/compare/3.2.2...3.2.3)
[diff](https://togithub.com/prettier/prettier/compare/3.2.2...3.2.3)
##### Throw errors for invalid code ([#15881](https://togithub.com/prettier/prettier/pull/15881) by [@fisker](https://togithub.com/fisker), [@Josh-Cena](https://togithub.com/Josh-Cena), [@auvred](https://togithub.com/auvred))
```ts

[Compare Source](https://togithub.com/prettier/prettier/compare/3.1.0...3.1.1)
[diff](https://togithub.com/prettier/prettier/compare/3.1.0...3.1.1)
##### Fix config file search ([#15363](https://togithub.com/prettier/prettier/pull/15363) by [@fisker](https://togithub.com/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.
```text
├─ .prettierrc
└─ test.js (A directory)
└─ .prettierrc
```
```js
// Prettier 3.1.0
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// /test.js/.prettierrc
// Prettier 3.1.1
await prettier.resolveConfigFile(new URL("./test.js", import.meta.url));
// /.prettierrc
```
##### Skip explicitly passed symbolic links with `--no-error-on-unmatched-pattern` ([#15533](https://togithub.com/prettier/prettier/pull/15533) by [@sanmai-NL](https://togithub.com/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](https://togithub.com/prettier/prettier/pull/15662) by [@auvred](https://togithub.com/auvred))
```jsx
// 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](https://togithub.com/prettier/prettier/pull/15663) by [@fisker](https://togithub.com/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](https://togithub.com/prettier/prettier/pull/15708) by [@sosukesuzuki](https://togithub.com/sosukesuzuki))
```tsx
// 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](https://togithub.com/prettier/prettier/pull/15718) by [@fisker](https://togithub.com/fisker))
[TypeScript 5.3](https://devblogs.microsoft.com/typescript/announcing-typescript-5-3/#import-attributes) supports the latest updates to the [import attributes](https://togithub.com/tc39/proposal-import-attributes) proposal.
```tsx
import something from "./something.json" with { type: "json" };
```
##### Fix false claim in docs that cursorOffset is incompatible with rangeStart/rangeEnd ([#15750](https://togithub.com/prettier/prettier/pull/15750) by [@ExplodingCabbage](https://togithub.com/ExplodingCabbage))
The cursorOffset option has in fact been compatible with rangeStart/rangeEnd for over 5 years, thanks to work by [@ds300](https://togithub.com/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](https://togithub.com/prettier/prettier/pull/15756) by [@fisker](https://togithub.com/fisker))
```js
// 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](https://togithub.com/prettier/prettier/pull/15757) by [@fisker](https://togithub.com/fisker))
```js
// 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 {};

Prettier v3 uses dynamic imports, user [will need to unplug Prettier](https://togithub.com/yarnpkg/berry/pull/5411#issuecomment-1523502224) when Yarn's PnP mode is enabled, add [`preferUnplugged: true`](https://yarnpkg.com/configuration/manifest#preferUnplugged) to `package.json`, so Yarn will install Prettier as unplug by default.
##### Support shared config that forbids `require()` ([#15233](https://togithub.com/prettier/prettier/pull/15233) by [@fisker](https://togithub.com/fisker))
If an external shared config package is used, and the package `exports` don't have `require` or `default` export.
In Prettier 3.0.2 Prettier fails when attempt to `require()` the package, and throws an error.
```text
Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /package.json
```
##### Allow argument of `require()` to break ([#15256](https://togithub.com/prettier/prettier/pull/15256) by [@fisker](https://togithub.com/fisker))
```jsx
// Input
const plugin = require(

### [`v3.3.3`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#333) [Compare Source](https://togithub.com/prettier/prettier/compare/3.3.2...3.3.3) [diff](https://togithub.com/prettier/prettier/compare/3.3.2...3.3.3) ##### Add parentheses for nullish coalescing in ternary ([#16391](https://togithub.com/prettier/prettier/pull/16391) by [@cdignam-segment](https://togithub.com/cdignam-segment)) This change adds clarity to operator precedence. ```js // 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](https://togithub.com/prettier/prettier/pull/16458) by [@y-schneider](https://togithub.com/y-schneider)) Prevent parentheses around member expressions or tagged template literals from being removed to follow the stricter parsing rules of TypeScript 5.5. ```ts // 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](https://togithub.com/prettier/prettier/pull/16474) by [@sosukesuzuki](https://togithub.com/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: ```html @let name = 'Frodo';Dashboard for {{name}}
Hello, {{name}} ``` For more details, please refer to the excellent blog post by the Angular Team: [Introducing @let in Angular](https://blog.angular.dev/introducing-let-in-angular-686f9f383f0f). We also appreciate the Angular Team for kindly answering our questions to implement this feature. ### [`v3.3.2`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#332) [Compare Source](https://togithub.com/prettier/prettier/compare/3.3.1...3.3.2) [diff](https://togithub.com/prettier/prettier/compare/3.3.1...3.3.2) ##### Fix handlebars path expressions starts with `@` ([#16358](https://togithub.com/prettier/prettier/pull/16358) by [@Princeyadav05](https://togithub.com/Princeyadav05)) ```hbs {{! Input }}{{ hello }}
`, }) export class AppComponent {} // Prettier 3.2.4 const template = "foobar"; @Component({ [template]: `{{ hello }}
`, }) export class AppComponent {} // Prettier 3.2.5 const template = "foobar"; @Component({ [template]: `{{ hello }}
`, }) export class AppComponent {} ``` ##### Use `"json"` parser for `tsconfig.json` by default ([#16012](https://togithub.com/prettier/prettier/pull/16012) by [@sosukesuzuki](https://togithub.com/sosukesuzuki)) In [v2.3.0](https://prettier.io/blog/2024/01/12/3.2.0#new-jsonc-parser-added-15831httpsgithubcomprettierprettierpull15831-by-fiskerhttpsgithubcomfisker), 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`](https://www.npmjs.com/package/linguist-languages) data. `tsconfig.json` is a special file used by [TypeScript](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html#using-tsconfigjson-or-jsconfigjson), it uses `.json` file extension, but it actually uses the [JSON with Comments](https://code.visualstudio.com/docs/languages/json#\_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 ```json { "overrides": [ { "files": ["tsconfig.json", "jsconfig.json"], "options": { "parser": "jsonc" } } ] } ``` ``` ``` ### [`v3.2.4`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#324) [Compare Source](https://togithub.com/prettier/prettier/compare/3.2.3...3.2.4) [diff](https://togithub.com/prettier/prettier/compare/3.2.3...3.2.4) ##### Fix incorrect parser inference ([#15947](https://togithub.com/prettier/prettier/pull/15947) by [@fisker](https://togithub.com/fisker)) Files like `.eslintrc.json` were incorrectly formatted as JSONC files. ```jsx // 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`](https://togithub.com/prettier/prettier/blob/HEAD/CHANGELOG.md#323) [Compare Source](https://togithub.com/prettier/prettier/compare/3.2.2...3.2.3) [diff](https://togithub.com/prettier/prettier/compare/3.2.2...3.2.3) ##### Throw errors for invalid code ([#15881](https://togithub.com/prettier/prettier/pull/15881) by [@fisker](https://togithub.com/fisker), [@Josh-Cena](https://togithub.com/Josh-Cena), [@auvred](https://togithub.com/auvred)) ```ts // Input 1++; // Prettier 3.2.2 1++; // Prettier 3.2.3 SyntaxError: Invalid left-hand side expression in unary operation (1:1) > 1 | 1++; | ^ ``` ```ts // Input try {} catch (error = 1){} // Prettier 3.2.2 try { } catch (error) {} // Prettier 3.2.3 SyntaxError: Catch clause variable cannot have an initializer.
