Simple JSON syntax checker

Required file pattern to check syntax. Default is '\\.json$'.

Optional base directory in which to look for files matching pattern.

If BASE is not set, json-syntax-check will look in GITHUB_WORKSPACE.

File names whose syntax check failed in JSON list format.

Your .github/workflows/jsoncheck.yml may look like:

name: JSON check

on:
  push:
    paths:
      - '**.json'
  pull_request:

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: json-syntax-check
        uses: limitusus/json-syntax-check@v2
        with:
          pattern: "\\.json$"
