I just trying the firebase cloud function. the index.ts is just a hello world. but I got the error when deploying the firebase cloud function.

I just follow along video tutorial from here: https://www.youtube.com/watch?v=DYfP-UIKxH0

i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint /Users/muchammadagunglaksana/Documents/Latihan/cloud_function/doug_youtube/functions
> tslint --project tsconfig.json

Running command: npm --prefix "$RESOURCE_DIR" run build

> functions@ build /Users/muchammadagunglaksana/Documents/Latihan/cloud_function/doug_youtube/functions
> tsc

src/index.ts:1:1 - error TS6133: 'functions' is declared but its value is never read.

1 import * as functions from 'firebase-functions';
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error.

here is the index.ts

import * as functions from 'firebase-functions';

// Start writing Firebase Functions
// https://firebase.google.com/docs/functions/typescript

export const helloWorld = functions.https.onRequest((request, response) => {
 response.send("Hello from Firebase!");
});

and this is my package.json

{
  "name": "functions",
  "scripts": {
    "lint": "tslint --project tsconfig.json",
    "build": "tsc",
    "serve": "npm run build && firebase serve --only functions",
    "shell": "npm run build && firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "8"
  },
  "main": "lib/index.js",
  "dependencies": {
    "firebase-admin": "^8.0.0",
    "firebase-functions": "^3.1.0"
  },
  "devDependencies": {
    "tslint": "^5.12.0",
    "typescript": "^3.2.2"
  },
  "private": true
}

what should I do ?

I suspect that you didn't save the source file before deploying. On disk, the function is probably still commented out, which would cause functions to go unused.

The issue is with new version of typscript, just disable this property from tsconfig.json "noUnusedLocals": false

{
"compilerOptions": {
"module": "commonjs",
"noImplicitReturns": true,
"noUnusedLocals": false,
"outDir": "lib",
"sourceMap": true,
"strict": true,
"target": "es2017"
},
"compileOnSave": true,
"include": [
"src"

] }
