Deploy MERN app on render.com without Yarn

Question

I'm trying to deploy only the server directory of my MERN app on render.com. I've found this link to the docs https://render.com/docs/deploy-node-express-app. The build command is using Yarn. However, my project is using NPM. What build command should I use? Also, what should the build script contain? I've only used Heroku before and do not remember having to run build command for the backend.

Answer 1

The build command when it comes about NPM on render.com for backend WEB SERVICE should be

npm install 

As we can read in dashboard render.com:

Build Command

This command runs in the root directory of your repository when a new version of your code is pushed, or when you deploy manually. It is typically a script that installs libraries, runs migrations, or compiles resources needed by your app.

For frontend STATIC SITE React.js should be

npm run build
