How to clean cache in heroku after installing dependencies?

问题

Topic : Heroku Problem : After installing my node js application in heroku, I made some changes in package.json. Now, when I am trying to push changes again, new dependencies are not getting installed. Heroku is picking the dependencies from cache.

How to disable cache in heroku ?

Thanks all for responding.

After much googling and spending time on my issue, I was able to solve my problem. I thought it would be better to post an answer if anyone faces the similar dilemma.

Below is the documentation, where I found my answer https://devcenter.heroku.com/articles/nodejs-support

1. By default, in heroku production is set to true. That's why only dependencies get installed. ( & skips devDependencies )

   heroku config:set NPM_CONFIG_PRODUCTION=false
   

Set production to false, to force heroku to install all packages.

** Only do this if doing development.

2. Heroku, by default, caches all the dependencies, so that the deployment is faster.

   heroku config:set NODE_MODULES_CACHE=false
   
   $ git commit -am 'disable node_modules cache' --allow-empty
   
   $ git push heroku master
   
   ** Preferable only if new dependencies are added in package.json
