Common Configuration

electron-builder configuration can be defined

in the package.json file of your project using the build key on the top level:
```
"build": {
  "appId": "com.example.app"
}
```
or through the --config <path/to/yml-or-json5-or-toml-or-js> option. Defaults to electron-builder.yml.
```
appId: "com.example.app"
```
json, json5, toml or js/ts (exported configuration or function that produces configuration) formats also supported.

Tip

If you want to use js file, do not name it electron-builder.js. It will conflict with electron-builder package name.

Tip

If you want to use toml, please install yarn add toml --dev.

Most of the options accept null — for example, to explicitly set that DMG icon must be default volume icon from the OS and default rules must be not applied (i.e. use application icon as DMG icon), set dmg.icon to null.

Artifact File Name Template¶

${ext} macro is supported in addition to file macros.

Environment Variables from File¶

Env file electron-builder.env in the current dir (example). Supported only for CLI usage.

How to Read Docs¶

Name of optional property is normal, required is bold.
Type is specified after property name: Array<String> | String. Union like this means that you can specify or string (**/*), or array of strings (["**/*", "!foo.js"]).
