Top 23 API Open-Source Projects

  • GitHub repo httpie

    As easy as /aitch-tee-tee-pie/ 🥧 Modern, user-friendly command-line HTTP client for the API era. JSON support, colors, sessions, downloads, plugins & more. https://twitter.com/httpie

    Project mention: Look at my new plugin to help run long commands | reddit.com/r/zsh | 2021-10-07

    Because this doesn't need to be sourced every time and, during development, like I am doing right now, it is constantly being changed. Add more, change existing etc. Imagine doing a web dev project and you are constantly creating and editing requests on postman. But you want to use a command line tool instead, such as https://httpie.io/. With this tool, it is easier to create those requests and run them on the command line. I'm willing to discuss this more with you. I believe this can be useful for many people and am having trouble marketing it haha.

    https://github.com/neovim/neovim/issues/16076 covers this topic, but it's not clear what exactly the approach should be at this stage.

  • GitHub repo slate

    Beautiful static documentation for your API

    Project mention: Favorite API Documentation UI/UX | reddit.com/r/api | 2021-06-04

    While not as visually impressive with flashy graphics and UI elements, Twilio's documentation has similar Stripe vibes as I believe it's built on Slate which is about as close to Stripe's framework as you can get. I like the theme used[4] in the code sample section as it's a nice break from the standard colors and it's easy on the eyes.

  • GitHub repo normalizr

    Normalizes nested JSON according to a schema

    Project mention: We just launched our product on Product Hunt which is entirely made with React Native | reddit.com/r/reactnative | 2021-09-08

    We've struggled with the navigation too. We rely on Interaction Manager and Pure component. We are trying to make sure no component should not render without a reason, we're still optimizing the app. I'd recommend this package called Why Did You Render. It helps us to find the culprit and mitigate it. And since our app is heavily relied upon Redux, we use normalizr for better optimization.

  • GitHub repo SWR

    React Hooks for data fetching

    Project mention: Can you technically use Redux as a secondary way to "cache" stuff while using it for its main purpose? | reddit.com/r/reactjs | 2021-10-16

    Yes you can and/but I use SWR for this. It's just a lightweight wrapper for fetch calls that dedupes and caches requests using local storage so I can call the same fetch any number of places in the app and still it will only request the data once (even across multiple open tabs).

  • GitHub repo insomnia

    Now, it's working on https://github.com/learn-anything/learn-anything and picking it up again.

  • GitHub repo JSDoc

    An API documentation generator for JavaScript.

    Project mention: Adding request and response validation to your Express REST API | dev.to | 2021-08-31

    The swagger-jsdoc package enables us to do this. It looks for JSDoc comments in code (annotated with an @openapi tag) to generate the OpenAPI specification.

  • GitHub repo Directus

    Project mention: Using CMS vs WordPress, question for an engineer. | reddit.com/r/webdev | 2021-10-07

    If you're looking for something simple, well made, and unopinionated your best bet might be Directus. It sits somewhere between a DB manager, a CMS, and auto-provisioned API. All the integration (frontend, SaaS, mobile app or otherwise) is left to the developers. I've only toyed with Directus but I can't wait to make a billable project with it.

    > but they don't realize how hard it is to build these systems correctly.

    In this case, it sounds like the SSNs were included in their entirety in the HTML. My first response is that its a stupid and obvious mistake, but I think it might be too suspiciously easy to only blame the developers here.

    I think we have a larger problem - which is that there's a hidden cost to adding extra layers of magic to software. And on the web, we seem to just not be able to help ourselves. The cost is that developers often skip actually understanding how the new layers work. And the abstractions are leaky with respect to performance and security, and sometimes functionality.

    Its easy to imagine how this bug slipped through. They had a database query which fetched the data for rendering. Then they used some "magic" framework which does server side rendering & hydration. So the server sent the JSON it used to render to the client to dehydrate the page, and that JSON happened to include the raw database rows (with SSNs). The system is magic enough so you don't have to understand how that process works; but not magic enough to protect you from the consequences.

    Junior devs use the magic anyway and get stuck, or make mistakes like this. Senior devs feel like we have to learn everything and get overwhelmed.

    Other examples of this:

    - Recently I wanted to use some rust code (compiled to wasm via wasm-pack) in a svelte project with snowpack or rollup. I know how to include wasm in a webpage, but the bundlers needed special plugins to handle this. And the plugins for wasm are halfbaked, poorly maintained and janky.

    - I worked with a team a few years ago who was using some graphql wrapper around contentful. (Before contentful had an official graphql endpoint). The wrapper was very good, but we needed to run some queries that weren't supported by the wrapper. This was close to impossible. Nobody on the team was strong enough to read the graphql code to figure out how to solve our problem. I did it eventually - via some custom endpoints. But I shouldn't have. After I left the team had no idea how to maintain or modify the code I wrote, and they were entirely stuck.

    - The "web obesity crisis" comes from projects pulling giant amounts of javascript into their webpages. Our tooling makes this easy (npm install) and safe (incompatible versions of the same package are included separately). So its easy to end up with libraries like web3, which include about a dozen different versions of bn.js resulting in 2.3mb of uncompressed JS which takes nearly a second to parse on a modern computer. - [1] https://github.com/ChainSafe/web3.js/issues/1178

    I don't know what the answer here is, but I know when I was writing qbasic as a kid it wasn't like this. Maybe we need to stop going "up the stack", and instead go sideways - throwing things out as we add more. I worry this whole problem will get much worse before it gets any better.

    Project mention: Free Customer Identity Access Management with Azure AD B2C | dev.to | 2021-10-08

    You can use any valid https URL instead, it doesn't matter for purpose of this tutorial because that URL is only here for legal reasons. For instance you could use https://httpbin.org/.
