Slow and Steady: Converting Sentry’s Entire Frontend to TypeScript

This page summarizes the projects mentioned and recommended in the original post on dev.to

Our great sponsors
  • Appwrite - The Open Source Firebase alternative introduces iOS support
  • Scout APM - Less time debugging, more time building
  • SonarQube - Static code analysis for 29 languages.
  • TypeScript

    TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

    TypeScript has an active community with a clear and maintained development roadmap in addition to rapid releases.

  • DefinitelyTyped

    The repository for high quality TypeScript type definitions. [Moved to: https://github.com/DefinitelyTyped/DefinitelyTyped] (by borisyankov)

    Many of the libraries we use (including React) already have type definitions available.

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • Sentry

    Sentry is cross-platform application monitoring, with a focus on error reporting.

    Sentry’s first Typescript Pull Request: https://github.com/getsentry/sentry/pull/13786

  • reflux

    A simple library for uni-directional dataflow application architecture with React extensions inspired by Flux

    One downside to relying on the type definitions in DefinitelyTyped is that occasionally the library types are not written by the maintainers. Instead, community users contribute types, and because of that some types are missing or incorrectly defined. We encountered this with the versions of ECharts and Reflux we were using. Our solution here was to add additional type definitions in our code.

  • TypeScript-slack-bot

    Small slack bot to get the current typescript conversion progress of sentry

    In addition, our fantastic tools team introduced a slackbot that would allow us to track progress on demand. Seeing the number go up every day was a big motivator in the final stages, so much so it’s something we’ll likely to use again. You can find the early versions of that bot here.

NOTE: The number of mentions on this list indicates mentions on common posts plus user suggested alternatives. Hence, a higher number means a more popular project.
