Update from mirror

• Version: electron-builder@17.3.0 electron-updater@1.16.0
• Target: windows, mac

My users are mostly in China, where can’t establish a stable connection to GitHub releases. I have a mirror server of GitHub releases, and wants to give a option to select mirror or GitHub as update server for users. But I have noticed that setFeedURL method is deprecated. Is there any other ways to set a mirror server besides GitHub release?

Deprecated as string url, but you can use setFeedURL (https://github.com/electron-userland/electron-builder/wiki/Auto-Update#module_electron-updater.AppUpdater+setFeedURL) to set configuration in runtime. And if url is string, it will be automatically converted into generic provider.

Hack for use ghproxy mirror to download

type Source = 'github.com' | 'ghproxy.com' | 'mirror.ghproxy.com'

const httpRequest = (Provider.prototype as any).httpRequest
;(Provider.prototype as any).httpRequest = function (url: URL, headers: Record<string, string>, ...args: any[]) {
  const source: Source = config.get('updater.source', 'github.com')

  if (source !== 'github.com') {
    headers['user-agent'] = 'curl/7.77.0'
    console.log('updater httpRequest', url.href)

    if (url.pathname.endsWith('.atom')) {
      url.host = 'github.com.cnpmjs.org'
      headers.accept = '*/*'
      headers['user-agent'] = 'curl/7.77.0'
      url.pathname = url.pathname.replace('/https://github.com', '')
    }
  }

  return httpRequest.call(this, url, headers, ...args)
}

const setFeedURL = autoUpdater.setFeedURL
autoUpdater.setFeedURL = async function (options: any) {
  setFeedURL.call(this, options)
  const source: Source = config.get('updater.source', 'github.com')
  const provider = await (this as any).clientPromise
  Object.defineProperty(provider, 'baseUrl', {
    get () {
      return new URL(`https://${source}/`)
    }
  })
  Object.defineProperty(provider, 'basePath', {
    get () {
      const basePath = `/${this.options.owner}/${this.options.repo}/releases`

      if (source.includes('ghproxy')) {
        return `/https://github.com${basePath}`
      }

      return basePath
    },
  })
}
