How do you use Node.js devDependencies in the App Platform builds?

How do you use Node.js devDependencies in the App Platform builds? Heroku automatically installs both the dependencies and devDependencies for the app build and then removes the devDependencies after the build is complete. This ensures that you’re only including the minimum required dependencies in production.

I resolve with this command.

  1. Install all dependency (prod and dev)
  2. Clean build folder
  3. Build API
  4. Clean and install production node modules
"build:digitalOcean": "yarn install --production=false && rimraf dist && yarn build && yarn install --production --frozen-lockfile"

I share my package script config

"scripts": {
    "build:digitalOcean": "yarn install --production=false && rimraf dist && yarn build && yarn install --production --frozen-lockfile",
    "build": "babel src --out-dir dist",
    "dev": "nodemon --exec yarn restart",
    "restart": "rimraf dist && yarn build && yarn start",
    "start": "node dist/index.js"
  }

I was able to resolve the issue by using npm install --production=false, then build.
