Linting results for CI (CircleCi)

[iliran11]

How is it possible to fail a CI build on CircleCi if Eslint generates an error or a warning?

Seems like the only access to linting results is through npm start.
However, this config file doesn't do the trick.

version: 2
jobs:
  build:
    docker:
      - image: circleci/node:7.10
    steps:
      - checkout
      - run: npm install
      - run: npm start

The build just hangs. I guess that start script doesn't return any exit status.

Change:

      - run: npm start

to:

      - run: CI=true npm run build
