## API
|
||
|
|
|
||
|
|
### decompress(input, [output], [options])
|
||
|
|
|
||
|
|
Returns a Promise for an array of files in the following format:
|
||
|
|
|
||
|
|
```js
|
||
|
|
{
|
||
|
|
data: Buffer,
|
||
|
|
mode: Number,
|
||
|
|
mtime: String,
|
||
|
|
path: String,
|
||
|
|
type: String
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
#### input
|
||
|
|
|
||
|
|
Type: `string` `Buffer`
|
||
|
|
|
||
|
|
File to decompress.
|
||
|
|
|
||
|
|
#### output
|
||
|
|
|
||
|
|
Type: `string`
|
||
|
|
|
||
|
|
Output directory.
|
||
|
|
|
||
|
|
#### options
|
||
|
|
|
||
|
|
##### filter
|
||
|
|
|
||
|
|
Type: `Function`
|
||
|
|
|
||
|
|
Filter out files before extracting. E.g:
|
||
|
|
|
||
|
|
```js
|
||
|
|
decompress('unicorn.zip', 'dist', {
|
||
|
|
filter: file => path.extname(file.path) !== '.exe'
|
||
|
|
}).then(files => {
|
||
|
|
console.log('done!');
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
*Note that in the current implementation, **`filter` is only applied after fully reading all files from the archive in memory**. Do not rely on this option to limit the amount of memory used by `decompress` to the size of the files included by `filter`. `decompress` will read the entire compressed file into memory regardless.*
|
||
|
|
|
||
|
|
##### map
|
||
|
|
|
||
|
|
Type: `Function`
|
||
|
|
|
||
|
|
Map files before extracting: E.g:
|
||
|
|
|
||
|
|
```js
|
||
|
|
decompress('unicorn.zip', 'dist', {
|
||
|
|
map: file => {
|
||
|
|
file.path = `unicorn-${file.path}`;
|
||
|
|
return file;
|
||
|
|
}
|
||
|
|
}).then(files => {
|
||
|
|
console.log('done!');
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
