Eslint Gitlab Codequality Formatter

Formatter that transforms ESLint reports into a format suitable for use with GitLab widgets.

The source code is hosted on GitLab. Although there is an automatic mirror of this repository on GitHub, all bug reports, feature requests, and merge requests should be submitted through GitLab.

Usage

Install eslint and @gitlab-formatters/eslint-formatter-gitlab using your package manager:

npm install --save-dev eslint @gitlab-formatters/eslint-formatter-gitlab

yarn add --dev eslint @gitlab-formatters/eslint-formatter-gitlab

To use in your project, simply run:

npx eslint . --format=@gitlab-formatters/gitlab

For integration with GitLab CI, add the following to your .gitlab-ci.yml:

eslint:
  image: node:20.14.0-alpine3.20
  stage: codequality
  script:
    - npm ci
    - npx eslint . --format=@gitlab-formatters/gitlab --output-file=gl-codequality.json
  artifacts:
    reports:
      codequality: gl-codequality.json

Report Example

Below is a JSON example of how the formatter reports issues.

This particular example outputs a detailed report that goes beyond the minimal fields required by GitLab's code quality widgets.

While GitLab requires only a subset of fields according to the Gitlab Code Quality specification, this formatter implements the full set of fields as outlined in the Code Climate Issue Data Type specification.

This comprehensive implementation enhances the depth of information available and facilitates better issue tracking and resolution.

[
  {
    "type": "issue",
    "check_name": "import/order",
    "description": "`./app.module` import should occur after import of `@nestjs/mongoose/dist/mongoose-core.module`",
    "content": {
      "body": "Error found in import/order"
    },
    "categories": [
      "Style"
    ],
    "location": {
      "path": "src/cli.ts",

        "end": {
          "line": 2,

  }
