## Code formatter
|
||
|
|
|
||
|
|
Deno ships with a built in code formatter that auto-formats TypeScript and
|
||
|
|
JavaScript code.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
# format all JS/TS files in the current directory and subdirectories
|
||
|
|
deno fmt
|
||
|
|
# format specific files
|
||
|
|
deno fmt myfile1.ts myfile2.ts
|
||
|
|
# check if all the JS/TS files in the current directory and subdirectories are formatted
|
||
|
|
deno fmt --check
|
||
|
|
# format stdin and write to stdout
|
||
|
|
cat file.ts | deno fmt -
|
||
|
|
```
|
||
|
|
|
||
|
|
Ignore formatting code by preceding it with a `// deno-fmt-ignore` comment:
|
||
|
|
|
||
|
|
```ts
|
||
|
|
// deno-fmt-ignore
|
||
|
|
export const identity = [
|
||
|
|
1, 0, 0,
|
||
|
|
0, 1, 0,
|
||
|
|
0, 0, 1,
|
||
|
|
];
|
||
|
|
```
|
||
|
|
|
||
|
|
Or ignore an entire file by adding a `// deno-fmt-ignore-file` comment at the
|
||
|
|
top of the file.
