Flow Type Reviews and Details

Social recommendations and mentions

• JavaScript Pattern Matching using 'match' with Flow

  If you haven’t looked at Flow recently: its syntax has grown so close to TypeScript that most code is hard to tell apart (here’s a side-by-side for TypeScript users). But Flow isn’t just type annotations: it adds first-class language features built for safety. - Source: dev.to / about 2 months ago

• Native Apps with ClojureScript, React and Static Hermes

  You may noticed there's untyped and typed JavaScript. When AOT compiling typed JavaScript, which can be a subset of either TypeScript or Flow, Hermes emits a more optimal C making it suitable for performance sensitive code, such as bindings to native libraries runnning in a hot loop. - Source: dev.to / 9 months ago

• Spirit Hunter - Post-Mortem

  Learning from the last year I realised that having robust pipeline to test archive size with a type checker is crucial for development and decided to prepare one. There are many boilerplates available (https://js13kgames.com/resources#boilerplates), so you do not need to create one yourself. However, I wanted to have flowtype support, so created one for myself. - Source: dev.to / almost 2 years ago

• $FlowFixMe in React source code

  Flow is a static type checker for JavaScript. Flow’s installation is easy and straightforward. - Source: dev.to / almost 2 years ago

• Handling dates in JavaScript with Tempo

  Date-fns is a JavaScript date-handling library written in TypeScript. It was first released in 2014. date-fns works in both the browser and Node.js. It also supports working with TypeScript and Flow (the JavaScript typechecker). date-fns is very popular, with 33.4K stars on GitHub and 20.5M npm weekly downloads, at the time of writing. - Source: dev.to / about 2 years ago

• 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 3 years 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 3 years 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 3 years 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 3 years 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: almost 4 years 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: almost 4 years 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: about 4 years ago

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

• 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: over 4 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: over 4 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 / almost 5 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 4 years ago

• Prop Types Question

• 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 / almost 5 years ago
