Notes on making blog app work with CI

Blog app is derived from what I made in full stack open part4&5, and CI is operated by Github Actions.

Create ./.env file from repo secrets, for dotenv to use:

- name: Create .env file
  run: |
    echo "TEST_MONGODB_URI = ${{secrets.TEST_MONGODB_URI}}" >> .env

Remember to add double qoutes as above.

Config Cypress options, in my case:

- name: e2e test
  uses: cypress-io/github-action@v2
  with:
    command: yarn test:e2e -q # -q slims the output
    start: yarn start:test
    wait-on: "http://localhost:3000"
    config: video=false # disable video recording

To avoid error spawnSync /bin/sh ENOBUFS thrown when Heroku deploys, remove directory ./node_modules right before deploy:
```
- name: remove files
  run: rm ./node_modules -rf
```
I don't know why but this way works.

Add scripts in husky hooks (e.g. in .husky/precommit or ./package.json), to avoid git commands during Heroku deployment triggering hooks:

if [[$CI -ne true]]; then # trigger before commit only when environment variable CI is not true
	yarn lint:fix # eslint auto fix
fi

"husky": {
  "hooks": {
    "pre-commit": "if [[$CI -ne true]]; then yarn lint:fix fi"
  }
}

Skip CI when only README file is pushed:

There are several ways.
1. Use Github's built-in feature to skip CI on any labeled commits. Include keywords in your commit message like [skip ci], [ci skip], [no ci], [skip actions], or [actions skip].
2. Ignore specified path in workflow file:
```
on:
push:
paths-ignore:
  - "README.md"
```
