| I advocated flow for two years, and I still find it interesting as a typesystem. But what finally led me to give up was the core team's lack of community engagement. It's very difficult get the team's attention to a bug or a question. As a result, they fail to see the common pain points of actual users. Typing higher order components is one common pain point that still doesn't have a clear solution. So, unless you're avoiding HOCs altogether, you can't really benefit from type annotations in your react codebase (you'll have too many implicit `any`s). You'll find more of these common use cases that flow doesn't optimise for. They're all over the issues section. Unfortunately, issues on Github generally don't get much attention from the team either, so I'm guessing users sometimes give up on reporting them. This has happened to me quite a few times. I didn't report some bugs because putting together a reduced test case takes time, and that time would be wasted if your issue is not gonna be paid attention to. What makes matters worse, is that there is no public roadmap. You don't know what the team's priorities are. You don't know when the bugs that affect your work are gonna get fixed, or some feature you need is gonna get implemented. You don't even know if it's on the radar. Of course, the Flow team is under no obligation to do any of that. They have no obligation to fix bugs for us or publish a roadmap. I'm already grateful that they've given us access to their work and without charging money. However, they do have the responsibility to communicate what their priorities are. If they're positioning Flow as an alternative to TypeScript, which is a well-supported, community-oriented project, then they should state clearly that Flow simply isn't. Call it a research project, or a project focused on a single company's use cases. Don't ask people to bet their own projects on it, when they clearly shouldn't. It'll be a big loss of productivity for them down the line, and your messaging is partly responsible for that. |
