Google Cloud Functions Emulatorの備忘録

最近Firebaseでcloud functionsを使用することが多く、Cloud Functions Emulatorで試す際に毎回つまってたのでその備忘録

インストール

npm
npm install -g @google-cloud/functions-emulator
yarn
yarn global add @google-cloud/functions-emulator

インストールができればfunctionsコマンドが使用できるようになるのですがzshの方は競合してしまうのでfunctions-emulatorに置き換えてください。

エミュレータの起動
functions start
※起動のエラーで毎回つまる。。

ERROR: Error: Emulator crashed! Check the log file...
    at ChildProcess.child.on (/Users/kohei/.npm-global/lib/node_modules/@google-cloud/functions-emulator/src/cli/controller.js:650:24)
    at ChildProcess.emit (events.js:182:13)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:240:12)

こちらパーミッションの問題なのでsudoつけて解決

sudo functions start

関数
index.tsに関数追加

index.ts
exports.hoge = functions.https.onRequest((request, response) => {
     console.log("hogehoge"))
     response.status(200).end()
})

ビルド
npm run build

関数のデプロイ

functions deploy デプロイする関数 --trigger-http

デプロイするとアクセスURLが貼られるのでアクセスして確認

ログ確認
functions logs read

エミュレータの停止
functions stop
