Front end networking

Because user engagement depends on reliable and effective network requests, you'll be asked to show you can use JavaScript to set up reliable front end networking protocols by:

  • Requesting data using fetch()
  • Checking response status, then parsing the data into usable format
  • Rendering response data to a page
  • Configuring POST requests to a database with method and body parameters
  • Using correctly configured cross-origin resource sharing protocol (CORS) fetch requests, depending on the server’s response headers
  • Handling fetch() request errors with promise chaining
  • Diagnosing network issues using debugging and development tools
