How to get Heroku to recognize a yarn.lock or package.json within a subdirectory (not root)

Question

I have a Rails application using React, Webpack, and Yarn for the client side. I have everything relating to the client side within the /client directory. This includes my yarn.

Answer 1

You can keep both package.json and yarn.lock by adding one of these to .slugignore.

It works like .gitignore - it just defines which files to ignore pushing to Heroku.
