Top 23 API Open-Source Projects

  • public-apis

    A collective list of free APIs

  • Project mention: Building a Basic Forex Rate Assistant Using Agents for Amazon Bedrock | dev.to | 2024-04-29

    For inspirations on what type of agents I should build, I turned to the Public APIs GitHub repository which has a curated lists of free APIs. I narrowed my search for an API that does not require sign-up or an API key and returns useful information. I ultimately decided to use the Free Currency Exchange Rates API, which seemed promising upon some basic testing.

  • Project mention: Why Neovim is My Text Editor of Choice | dev.to | 2024-04-23

    As a software engineer, choosing and understanding your text editor is important part of your work, as it impacts your productivity and workflow efficiency. It's like choosing the perfect tool for any trade - you need to know what tool to use and how to use it effectively if you want to excel. For me, I use Neovim as my editor and I have been using it for a little over a year now.

    > 2. ORMs do not hide SQL nastiness.

    This is certainly true!

    I mean: ORMs are now well known to "make the easy queries slightly more easy, while making intermediate queries really hard and complex queries impossible".

    I think the are of ORMs is over. It simply did not deliver.

    If a book on SQL is --say-- 100 pages, a book on Hibernate is 400 pages. So much to learn just to make the easy queries slightly easier to type? Just not worth it.

    I prefer jooq any day over ORMs. And dont get me started over what tools like Hasuna have to offer.

    There are also some languages (forgot the names) that are SQL-done-right. Select in the back, more type safe, more logic, more in the same steps as the query gets executed. These need to be adopted by PG and MySQL and we're good to go. (IMHO)

    REST API for any Postgres database

  • Project mention: Supabase – General Availability Week | news.ycombinator.com | 2024-04-15

    hey hn, supabase ceo her

    we just announced GA, after ~4 years of beta. for those who don't know: supabase is a postgres hosting company. we also host other open source "backend" tools that make it easy to get started with postgres (tools like PostgREST for auto-generate APIs [0])

    we owe a lot to the HN community. you launched us 4 years ago [1], when we were just a few developers. since then HN has been a staple in our journey, one of the best sources of product feedback [2]

    the GA badge is mostly to signify organizational readiness. we're at a stage where we can take any profile of customer. we have a support team that works 24/7, and a success team that will help customers improve their postgres usage. we released our Index Advisor [3] yesterday, and we'll be releasing a few more products this week that helps customer with performance and security.

    on a personal note: i read HN most days, and love going through the ShowHN's to see what devs are building. thanks for being an awesome community and my favorite place to lurk on the internet. i'll stick around to answer any questions

  • openapi-generator

    OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)

  • Project mention: The Stainless SDK Generator | news.ycombinator.com | 2024-04-24

    Disclaimer: We're an early adopter of Stainless at Mux.

    I've spent more of my time than I'd like to admit managing both OpenAPi spec files [1] and fighting with openapi-generator [2] than any sane person should have to. While it's great having the freedom to change the templates an thus generated SDKs you get with using that sort of approach, it's also super time consuming, and when you have a lot of SDKs (we have 6 generated SDKs), in my experience it needs someone devoted to managing the process, staying up with template changes etc.

    Excited to see more SDK languages come to Stainless!
