Flow Type Reviews and details

Social recommendations and mentions

• Is TypeScript actually worth It?

  I love JS, but I want types. I don't want TypeScript though, but I'll do it if the job requires it. Has anyone tried building in flow for a large project? This was facebook's static type checking approach: https://flow.org/. - Source: Hacker News / over 1 year ago

• How I improved my JS code with these 3 functions

  In my examples, I’ll use the Flow type system so that it’s easier to follow the idea. The code consists of two parts: a service API and a recommendation flow. - Source: dev.to / over 1 year ago

• Guido van Rossum: Python and the Future of Programming | Lex Fridman Podcast #341

  You think we could try to make it such that people use JS + Flow the static type checker. Source: over 1 year ago

• Front-end Guide

  The two biggest contenders in adding static types to JavaScript are Flow (by Facebook) and TypeScript (by Microsoft). As of date, there is no clear winner in the battle. For now, we have made the choice of using Flow. We find that Flow has a lower learning curve as compared to TypeScript and it requires relatively less effort to migrate an existing code base to Flow. Being built by Facebook, Flow has better... - Source: dev.to / over 1 year ago

• Flow - a little language I've been working on

  Just FYI, Facebook has a JS dialect called Flow. There was a point in time that Flow and TypeScript were duking it out, but clearly TS has won. I think Flow is still used inside Facebook, but I don't think it has really caught on in the larger developer ecosystem. Source: over 1 year ago

• State Machines II

  Having worked quite a lot with the flow static typing system for JavaScript, I can assure you that I have missed this feature multiple times in the past 6 years of using Rust. Source: over 1 year ago

• prevent FlowType to check error in node_modules

  I wanted to configure flow for my project, but there was no .flowconfig file.As we know that the flow version is needed to be specified for installing flow locally for the project, using the following script:yarn add --dev flow-bin@0.79.1 babel-preset-flow. Source: almost 2 years ago

• Can someone explain to me why Typescript is needed in the days of ECMA 11?

  Left out the part where Facebook wrote their own type system, flow. Source: about 2 years ago

• Microsoft proposes type syntax for JavaScript

  But if you read through the proposal it is not just restricted to TyeScript. They are thinking of avoiding the transpilation process and doing that within the browser. That's the reason it's not just TS they are planning to include other solutions like Flow as well. Source: about 2 years ago

• Should I migrate to TS?

  My experience is that React has excellent type support. I think they have been using Flow from pretty much the beginning. TypeScript support is, in my opinion, much better than in Angular, which is a bit ironic since Angular is written in TypeScript. Source: about 2 years ago

• Differences between TypeScript and Elm

  An alternative to TypeScript can be Flow, a library maintained by Facebook. Flow, similarly to TypeScript, is not a sound type system. "Flow tries to be as sound and complete as possible. But because JavaScript was not designed around a type system, Flow sometimes has to make a tradeoff". Another alternative is Hegel, a type system that "attempts" to be sound. It is unclear to me if the attempt succeeded or not... - Source: dev.to / over 2 years ago

• Personal Training Website Project

  For this I've chocen to work with "The React Framework For Production" - NextJS, cuz you know, I will need a strong SEO optimization for the website. Also I may try to implement Typescript or Flow I still need to check what will be more beneficial (Feel free to share your thoughts). Since I'm not good at HTML / CSS, responsive and all that fancy things, I will most probably use a theme from theme-forest that I... - Source: dev.to / over 2 years ago

• Prop Types Question

  It’s to help provide some level of type safety in your React application if you’re not actively using something like Flow or Typescript for typing. Source: over 2 years ago

• How Relevant is Still TypeScript in 2021?

  A couple of years ago, Facebook’s own type system – Flow – was competing neck and neck with TypeScript for the crown of type systems. Flow’s claim to fame was that you really didn’t need to write that many type definitions; great type inference and refinements would give you precise types at breakneck speeds. - Source: dev.to / over 2 years ago

• Thinking in ReScript

  ReScript is a new language targeting JavaScript programmers. Particularly JavaScript programmers that have developed an interest in type safety with TypeScript or Flow. - Source: dev.to / over 2 years ago

• How to design a Type Friendly Context

  Everything seems perfect until static type system join the game, Which is bring in by TypeScript and Flow. With the safe type checking and powerful editor lsp features, people use them to build not only large systems, but also small apps and tools. - Source: dev.to / over 2 years ago

• Substitutes for Typescript

  Hey, If you want to keep using JS with safety, I recommend this https://flow.org ;). Source: almost 3 years ago

• What do I need to learn to understand React under the hood?

  The React codebase is written in Flow, a static types layer on top of JS. It's similar to TypeScript in syntax and concepts, but a completely different tool: https://flow.org/. Source: almost 3 years ago

• But really, it is

  I think the downvotes are somewhat unfair (from someone who is also a heavy typescript user) but the dogma surrounding it can sometimes be a bit too much. I think there's sitatations where it's warranted and sometimes where it's completely overkill, many robust languages have survived without types just fine. But if you're after a static type checker, I would recommed checking out Flow. Source: almost 3 years ago

• TypeScript

  I wonder why Flow Language has not penetrated the market as TypeScript guess the latter is backed by a big corporation and has a supportive community. Anyway, that's just my opinion. - Source: dev.to / almost 3 years ago
