Getting Started

Install the package:

npm install --save-dev structlint

in case you prefer yarn

yarn add -D structlint

then add the config into a .structlintrc file. For example:

.structlintrc

{
  "structure": [
    {
      "description": "Core application business logic",
      "path": "./modules",
      "disallowedImports": [
        {
          "glob": "./components/**/*",
          "message": "Business logic should never import UI components"
        }
      ]
    },
    {
      "description": "Reducers",
      "path": "./reducers",
      "disallowedImports": ["./components/**/*", "./sagas/**/*"],
      "allowedImports": ["./utils/**/*"]
    }
  ]
}

You can have a single config file at the root of your project or multiple configs, one for every major sub directory.

- src
  - reducers
    - .structlintrc
    - user.reducer.js
    - settings.reducer.js
    - profile.reducer.js
  - components
    - .structlintrc
    - Header
      - Header.js
      - Header.scss
    - Footer
      - Header.js
      - Header.scss
   - sagas
     - .structlintrc
     - auth.saga.js
     - profile.saga.js
   - utils
     - .structlintrc
     - color.js
     - url.js
- tests
  - .structlintrc
  - user-tests
  - settings-tests

Usage

Run from the root of your project:

<path-to-node-modules>/.bin/structlint

OR

npx structlint

Structlint will recursively go through the sub-directories and lint them. If you prefer to lint just one sub-directory, you must change the directory before running the command: cd tests && structlint.

Config options
