How to set up and validate locally

1. License: GitLab Starter
2. Make sure your local environment has configured code quality.
   For the configuration method, please refer to the gitlab documentation: https://docs.gitlab.com/...
   If you can see the code quality results on the pipeline page, the configuration is successful:
   
3. Open the GraphiQL page(http://127.0.0.1:3000/-/graphql-explorer) and execute the query

   {
     project(fullPath: "flightjs/Flight") {
       id
       pipeline(iid: 2) {
         id
         codeQualityReportSummary {
           count
           blocker
           critical
           major
           minor
           info
           unknown
         }
       }
     }
   }
