Github Action: Validate JSON

A GitHub Action that validates 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 under the repository of a JSON schema file to validate the other JSON files with. Default is: './schema.json'.
• jsons: One or more relative file paths under the repository (seperated by comma) of the JSON files to validate with the schema provided.

Note: schema is required, otherwise default will be used.

Outputs

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

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
        uses: docker://orrosenblatt/validate-json-action:latest
        env:
          INPUT_SCHEMA: /path/to/schema.json
          INPUT_JSONS: /path/to/file.json,/path/to/another/file.json

TODOs

• Initial validation action
• Docker
• Automate release process
• Github workflow screenshots
• Support exclude & include in PRs (JSONs from pattern)
• Support schema & jsons by external reference (from S3/GitHub/etc...)
• Support delimiter input
