I don't know about the quality, but Mattermost is in TS: https://github.com/mattermost/mattermost-webapp

On the web platform end, we merged the upgrade to React 17 (again) into master, and performed a bunch of (more minor) dependency updates while at it. We also continue our journey towards using MUI-based menus.

On the web platform end, we continue the work on menu components, found and fixed the issue that marked a whole lot of channels as unread last week (with GarphQL enabled). We’ve also been working on performance regression tests. And we’re upgrading moar dependencies.

On the web platform end, the team has been working on unifying post components (and cleaning up afterwards), more fighting with Webpack and friends in the context of the front-end part of the multi-product architecture, testing out a prototype of menus based on Material UI, and the regular cycle of dependency updates.

On the web platform end, beside being overwhelmed by anticipation of the upcoming new joiners, we’re making good progress in getting webpack federation ready to be merged. This will be a solid step towards the multi-product architecture on the front-end. The upgrade to React 17 is also almost there. Beyond that, as mentioned, we’re fixing a few issues in GraphQL before we enable it again on community.

On the web platform end, we are experimenting with “theme weeks” as a budgeting hack to work on important but not urgent stuff. This first theme week (and this will likely be a recurring one) is focused on 🥁 performance! We’re pulling in a whole bunch of tickets accumulated over time of smaller things we can optimize for performance. Some of these improvements are already landing.

Platform involves work in many of our “highest traffic” repositories. I’m still figuring out reasonable ways how to keep up with what’s happening in the webapp, server, mobile repos as well as everything related to QA.

Most projects on GitHub have CONTRIBUTING.md file which describes how you can contribute, so you can start from there. Generally I'd say getting to meaningful contributions is very difficult for someone without real-world development experience, so if you choose to do this it won't be easy. On the other hand, this is precisely why employers prefer people who already have this experience -- it takes time and effort and not everyone makes it even with support from senior collegues.

Mattermost was the closest I was able to find and until their cloud beta finishes you have to setup a server to run them. With a Github or Google identity you are one click away from running Uclusion (and with any email several clicks) - no credit card required.

Zod is an open-source schema declaration and validation library that emphasizes TypeScript. It can refer to any data type, from simple to complex. Zod eliminates duplicative type declarations by inferring static TypeScript types and allows easy composition of complex data structures from simpler ones. It has no dependencies, is compatible with Node.js and modern browsers, and has a concise, chainable interface. Zod is lightweight (8kb when zipped), immutable, with methods returning new instances. It encourages parsing over validation and is not limited to TypeScript but works well with JavaScript as well.

Zod is a TypeScript-first schema declaration and validation library. It helps create schemas for any data type and is very developer-friendly. Zod has the functional approach of "parse, don't validate." It supports coercion in all primitive types.

You can check out their documentation here.

You can learn more about Zod on their website here.

In JS, it's a good idea anyway to use some JSON parsing library instead of JSON.parse.

With Zod, you can use z.bigint() parser. If you take the "parse any JSON" snippet https://zod.dev/?id=json-type and change z.number() to z.bigint(), it should do what you are looking for.

We will validate our input using client-side zod. Zod handles TypeScript-first schema validation with static type inference. This means that it will not only validate your fields, it will also set types on validated fields.

A word of warning: while discriminated unions are very powerful, there's an ongoing discussion on whether discriminated unions should be deprecated and replaced with a different API.

I was first introduced to Zod by Adam Bobrow - a colleague of mine and a dear friend. Adam was sick and tired from JavaScript's brittleness, and about two years ago he started migrating our code base to TypeScript. But that wasn't enough for him. He kept complaining: "What good are my types, if some other service decides to send me bad data and breaks my code?". That's when he discovered Zod.
