How to clean cache in heroku after installing dependencies?


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 ?


Solution

  • 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.
    
    1. 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
