Configuration for prettier

#prettier

What and Why prettier?

Prettier is a code formatter, which supports many kinds of language from Programming languages (JXS, TS), to Style sheets (CSS, SCSS), and also Serialization languages (YAML).

As we can see in the gif above, it will take a lot of time to arrange those lines, and even more for HTML. Prettier is the light from heaven, just saving the file everything will be in order

Configuration

My configuration

My beloved configuration is below



{
  "singleQuote": true,
  "trailingComma": "all",
  "useTabs": false,
  "tabWidth": 2,
  "overrides": [
    {
      "files": "*.yaml",
      "options": {
        "tadWidth": 2,
        "printWidth": 40,
        "singleQuote": true
      }
    }
  ]
}

To use

First of all, we need to install Prettier with flag --save-dev, because it is just useful for development, but not production. Without --save-dev, our production package will containts many unused modules (reference about dependencies vs devdependencies) ```

npm

npm i --save-dev prettier

yarn

yarn add --dev prettier

- Create 2 files `.prettierrc`, `.prettierignore` in our root level, the former is for configuration and the latter is for ignoring directories. Usually, I ignore `build` and `coverage`, which is generated from build production package and test result corresponding.

- Done!!

_Notes:_ Instead of `.prettierrc`, `prettier` also supports a wide range of types. Please take a look at [Configuration File](https://prettier.io/docs/en/configuration.html).

##Other options
You can find more interesting ways to use it in [prettier documentation](https://prettier.io/docs/en/options.html), such as lint-staged, pre-commit, and so on.

I usually due with CloudFormation, so besides a general configuration, I `overrides` it with my favorite style for `.yaml`. You can find your own one while [playing around](https://prettier.io/playground/) with it.
