Change the default update cache folder and default installation folder location

• Electron-Builder Version: 22.14.13

• Node Version: 16.15.0

• Electron Version: 19.0.1
• Electron Type (current, beta, nightly): current

• Target: windows, linux

The default folder name uses the package.json name, I want to be able to simply configure it using the api, using the appIdor a separate field

I found the beforePack hook function and I changed the value of the metadata and it took effect. I don’t know if there are any side effects though.

beforePack: (context) => {
  context.packager.info.metadata.name = "hello";
},

app-update.yml

provider: generic
url: http://127.0.0.1:8080
useMultipleRangeRequest: false
updaterCacheDirName: hello-updater

I browsed the source code and it will merge the content of the extraMetadata, so just configure the value of name in the extraMetadata and there is no need to use beforePack.

// packages\app-builder-lib\src\fileTransformer.ts
async function modifyMainPackageJson(file: string, extraMetadata: any, isRemovePackageScripts: boolean, isRemovePackageKeywords: boolean) {
  const mainPackageData = JSON.parse(await readFile(file, "utf-8"))
  if (extraMetadata != null) {
    // !!!
    deepAssign(mainPackageData, extraMetadata)
  }

  // https://github.com/electron-userland/electron-builder/issues/1212
  const serializedDataIfChanged = cleanupPackageJson(mainPackageData, {
    isMain: true,
    isRemovePackageScripts,
    isRemovePackageKeywords,
  })
  if (serializedDataIfChanged != null) {
    return serializedDataIfChanged
  } else if (extraMetadata != null) {
    return JSON.stringify(mainPackageData, null, 2)
  }
  return null
}
