はじめに
firebase functionを使えるようにした際、知らず知らずにESLintを有効にしてしまっていた。今回は対処した際の方法を紹介。
問題

ESLintで引っかかっているようだ。
ふりかえり
そもそも、本当にESLintを有効にしたんだっけ。。
どのようにfirebase functionを有効にしたか振り返る。
firebase init functions

You're about to initialize a Firebase project in this directory:
/Users/coco/Documents/firebase-auth
Before we get started, keep in mind:
* You are initializing in an existing Firebase project directory
=== Project Setup
First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add,
but for now we'll just set up a default project.
i .firebaserc already has a default project, using auth-xxx.
=== Functions Setup
A functions directory will be created in your project with a Node.js
package pre-configured. Functions can be deployed with firebase deploy.
? What language would you like to use to write Cloud Functions? JavaScript
? Do you want to use ESLint to catch probable bugs and enforce style? Yes
✔ Wrote functions/package.json
✔ Wrote functions/.eslintrc.json
✔ Wrote functions/index.js
✔ Wrote functions/.gitignore
? Do you want to install dependencies with npm now? Yes

しっかりESLintを有効にしてた。
現在の設定を確認
firebase.jsonを確認する
cat firebase.json
{
"database": {
"rules": "database.rules.json"
},
"hosting": {
"public": "public",
"rewrites": [
{
"source": "**",
"function": "firebaseAuth"
}
],
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
]
},
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint"
]
}
}
黄色の箇所を削除し、再度“` firebase deploy“`を行うと、ESlintが行われずdeployされる。
