"babel: not found" while deploying to heroku about express-es6-rest-api

[hpdobrica]

I had the same problem, it's because heroku doesn't automatically install dev-dependencies for npm, you need to set config variable NPM_CONFIG_PRODUCTION in heroku to false and it will work :)

This is just an oddity of Heroku - they run your build and deploy from Git (both development tools), but don't install development modules. In general, I would recommend setting NPM_CONFIG_PRODUCTION=false on Heroku.

in script use

"start":"babel-node index.js" instead of using "start":"babel index.js"

This should not be used for production.

can any one suggest how to use es6 in heroku with babel

Hi today I've been trying to do this myself. I've figured it out.
First, lets assume you setup babel correctly by using the command:
npm install --save-dev @babel/core @babel/cli

Inside package.json the result should be:

{
  "devDependencies": {
+   "@babel/cli": "^7.0.0",
+   "@babel/core": "^7.0.0"
  }
}

Now to the solution:
Other repo issues that mentioned this issue said you need to set the environment variable NPM_CONFIG_PRODUCTION=false, this can be done inside settings or via the console with command: heroku config:set NPM_CONFIG_PRODUCTION=false, and apparently the reason is because heroku does not install dev dependencies on production and in order for 'babel' to be defined development dependencies need to be installed.

Hopefully this should fix yours and anyone else's issue.

Close this issue as it's nothing to do with this repository, this problem lies with Heroku.

NPM_CONFIG_PRODUCTION
