Validate JSON Github Action

Easy to use GitHub Action to validate JSON files based on a JSON Schema.

This project uses ajv, fast JSON schema validator, to perform the validation.

Usage

Inputs

• schema: Relative file path in the repository to a JSON schema file to validate the other JSON files with. If no value is provided ./schema.json will be used.
• jsons: One or more relative file paths under the repository (separated by commas) of the JSON files to validate with the schema provided. Glob paths can be used as well (wildcard matching).

Outputs

• invalid: One or more of relative file paths of the invalid JSON files, found in the repository (separated by commas).

Example Workflow

An example .github/workflows/validate.yml workflow to run JSON validation on the repository:

name: Validate JSONs

on: [pull_request]

jobs:
  verify-json-validation:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - name: Validate JSON with Glob
        uses: nhalstead/[email protected]
        with:
          schema: /path/to/schema.json
          jsons: /path/to/file.json,/path/to/another/file.json
