### What does Diode do?
Third party APIs make it easy to integrate functionalities across apps. But using them on a purely front-end project is a hassle. Most of the time, the API endpoints require an API key which cannot be exposed on the frontend. Hence, most of us setup a proxy backend server that makes the request to the third party API with the API keys and make the frontend request this proxy server instead. While it might be a trivial solution that shouldn't take a lot of time to implement, it can get very repeatable and tedious over time.

**Diode solves this** problem by abstracting this proxy server and allowing you to add and configure as many API routes and consume them directly on the frontend **without having to worry about exposing any API keys**! Since Diode sits in between all the requests going to the third-party server, it also makes it easy to add **commonly used middlewares to the API route** with just a click!  
_Fun fact: All of this happens without you having to write a single line of code._

### Features
- 💡 Easy to use dashboard.
- ⏩ Query parameters and request headers forwarding.
- 🕶️ Encrypted Secrets that get dynamically injected when making request.
- 🔮 Request and Response structure preservation.
- One-click middlewares for:
  - 🚫 IP/HTTP restriction
  - ⏱️ Rate-limiting
  - 📌 Caching
- 💙 Open source, can be self-hosted.
