  • SurveyJS - Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • WorkOS - The modern identity platform for B2B SaaS
  • supertest

    🕷 Super-agent driven library for testing node.js HTTP servers using a fluent API. Maintained for @forwardemail, @ladjs, @spamscanner, @breejs, @cabinjs, and @lassjs.

    If the latter, there are a bunch of different options for writing automated tests. One popular way is using Jest to run your tests. If you're trying to test the backend end-to-end flow, you could use Supertest to make requests and assert on the responses.

  • jest

    Delightful JavaScript Testing.

  • SurveyJS

    Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  • libcurl

    A command line tool and library for transferring data with URL syntax, supporting DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT, POP3, POP3S, RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS. libcurl offers a myriad of powerful features

    If the former, and if you want to strictly use the terminal, you can use curl. If you're open to using another program, there are REST clients such as Postman or Insomnia which enable you to make REST requests to your application. Also, I know that VSCode has a REST client extension and IntelliJ products come with REST clients built in (if you use either of those).
