# @electron/get
> Download Electron release artifacts
[](https://github.com/electron/get/actions/workflows/test.yml)
[](https://npm.im/@electron/get)
## Usage
For full API details, see the [API documentation](https://electron.github.io/get/).
### Simple: Downloading an Electron Binary ZIP
```typescript
import { download } from '@electron/get';
// NB: Use this syntax within an async function, Node does not have support for
// top-level await as of Node 12.
const zipFilePath = await download('4.0.4');
```
### Advanced: Downloading a macOS Electron Symbol File
```typescript
import { downloadArtifact } from '@electron/get';
// NB: Use this syntax within an async function, Node does not have support for
// top-level await as of Node 12.
const zipFilePath = await downloadArtifact({
version: '4.0.4',
platform: 'darwin',
artifactName: 'electron',
artifactSuffix: 'symbols',
arch: 'x64',
});
```
### Specifying a mirror
To specify another location to download Electron assets from, the following options are
available:
* `mirrorOptions` Object
* `mirror` String (optional) - The base URL of the mirror to download from.
* `nightlyMirror` String (optional) - The Electron nightly-specific mirror URL.
* `customDir` String (optional) - The name of the directory to download from, often scoped by version number.
* `customFilename` String (optional) - The name of the asset to download.
* `resolveAssetURL` Function (optional) - A function allowing customization of the url used to download the asset.
Anatomy of a download URL, in terms of `mirrorOptions`:
```
https://github.com/electron/electron/releases/download/v4.0.4/electron-v4.0.4-linux-x64.zip
| | | |
------------------------------------------------------- -----------------------------
| |
mirror / nightlyMirror | | customFilename
------
||
customDir
```
Example:
```typescript
import { download } from '@electron/get';
const zipFilePath = await download('4.0.4', {
mirrorOptions: {
mirror: 'https://mirror.example.com/electron/',
customDir: 'custom',
customFilename: 'unofficial-electron-linux.zip'
}
});
// Will download from https://mirror.example.com/electron/custom/unofficial-electron-linux.zip
const nightlyZipFilePath = await download('8.0.0-nightly.20190901', {
mirrorOptions: {
nightlyMirror: 'https://nightly.example.com/',
customDir: 'nightlies',
customFilename: 'nightly-linux.zip'
}
});
// Will download from https://nightly.example.com/nightlies/nightly-linux.zip
```
`customDir` can have the placeholder `{{ version }}`, which will be replaced by the version
specified (without the leading `v`). For example:
```javascript
const zipFilePath = await download('4.0.4', {
mirrorOptions: {
mirror: 'https://mirror.example.com/electron/',
customDir: 'version-{{ version }}',
platform: 'linux',
arch: 'x64'
}
});
// Will download from https://mirror.example.com/electron/version-4.0.4/electron-v4.0.4-linux-x64.zip
```
#### Using environment variables for mirror options
Mirror options can also be specified via the following environment variables:
* `ELECTRON_CUSTOM_DIR` - Specifies the custom directory to download from.
* `ELECTRON_CUSTOM_FILENAME` - Specifies the custom file name to download.
* `ELECTRON_MIRROR` - Specifies the URL of the server to download from if the version is not a nightly version.
* `ELECTRON_NIGHTLY_MIRROR` - Specifies the URL of the server to download from if the version is a nightly version.
### Overriding the version downloaded
The version downloaded can be overriden by setting the `ELECTRON_CUSTOM_VERSION` environment variable.
Setting this environment variable will override the version passed in to `download` or `downloadArtifact`.
## How It Works
This module downloads Electron to a known place on your system and caches it
so that future requests for that asset can be returned instantly. The cache
locations are:
* Linux: `$XDG_CACHE_HOME` or `~/.cache/electron/`
* MacOS: `~/Library/Caches/electron/`
* Windows: `%LOCALAPPDATA%/electron/Cache` or `~/AppData/Local/electron/Cache/`
By default, the module uses [`got`](https://github.com/sindresorhus/got) as the
downloader. As a result, you can use the same [options](https://github.com/sindresorhus/got#options)
via `downloadOptions`.
### Progress Bar
By default, a progress bar is shown when downloading an artifact for more than 30 seconds. To
disable, set the `ELECTRON_GET_NO_PROGRESS` environment variable to any non-empty value, or set
`quiet` to `true` in `downloadOptions`. If you need to monitor progress yourself via the API, set
`getProgressCallback` in `downloadOptions`, which has the same function signature as `got`'s
[`downloadProgress` event callback](https://github.com/sindresorhus/got#ondownloadprogress-progress).
### Proxies
Downstream packages should utilize the `initializeProxy` function to add HTTP(S) proxy support. If
the environment variable `ELECTRON_GET_USE_PROXY` is set, it is called automatically.
### Debug
[`debug`](https://www.npmjs.com/package/debug) is used to display logs and messages.
Set the `DEBUG=@electron/get*` environment variable to log additional
debug information from this module.
