Twig Education ESLint Config
npm install eslint-config-twig1. If you don't already have a package.json file, create one with npm init or yarn init.
2. Then install everything needed by the config:npx install-peerdeps --dev eslint-config-twig
3. Create a .eslintrc config file in the root of your project if you don't have one already and add the twig config to it.
``
{
"extends": [
"twig"
]
}
4. Add a script to your package.json to lint your code:
`
"scripts": {
"lint": "eslint ./",
},
5. The twig eslint config uses eslint-config-compat. This will lint your code for browser compatibility. There are default settings but we recommend adding these settings to your package.json file for Twig Science projects:
`
"browserslist": [
"defaults",
"ios_saf >= 14",
"not op_mini all"
]
6. Create a .prettierrc file containing the following:
`
{
"trailingComma": "all",
"tabWidth": 4,
"semi": true,
"singleQuote": true,
"printWidth": 120,
"arrowParens": "avoid"
}
The .prettierrc file is required as editor extensions such as prettier-atom and prettier-vscode will read the .prettierrc file to auto format files.
7. Now you can manually lint your code by running yarn lint
If you'd like to overwrite the eslint settings, you can add the rules in your .eslintrc file. The ESLint rules go directly under "rules".
`
{
"extends": [
"twig"
],
"rules": {
"no-console": 2,
}
}
