No need to build your own WebSocket to handle it. The payload is the minimal possible size. So you always use the data according to the proto definition. You can only interact with the API and data via the proto generated classes. Both the backend and the frontend uses the proto files as the source of truth. Let's say we want to get information about a user. Let's see an example comparing sending a JSON data via REST vs gRPC. # High-performance, minimal payloadįrom the slogan "A high-performance, open-source universal RPC framework", you can see the emphasis on performance. It's widely used inside Google, and a few more big-name companies. And GraphQL is the new hotness recently.). This might be the less well-known one (REST is the oldest, with native support. Nothing prevents you from making GET /list delete all the items. You have the total control of what you do, so you can have APIs with inconsistent naming, behavior. And whenever the backend changes, the frontend also needs to keep changes in sync manually. The frontend has to know the path, method, request format, etc. As you can see, there's no contract between the backend and the frontend. Need the backend and the frontend in sync.(But building a good one definitely requires more work) As you can see above, it's just a few lines of code to build and use REST API. You use it almost anywhere - within your app, inside browser devtool, or just curl. HTTP is the backbone of the web, so any platform / language come with it. Here's the backend implementation (example in Express.js). Whenever an HTTP request hits the path, do something and respond back data. The design of REST API is fairly straightforward: The backend exposes a path. To start, this is a basic structure of REST APIs. This is the most well-known type - whether you heard of the terms "REST", "RESTful API", if you have used an API, that you can simply call via curl command in bash of fetch in JavaScript, you are using REST API. Tech jargon aside, we can simplify them as three ways to build & use APIs. (Interestingly, I just found out on Wikipedia - Both gRPC and GraphQL started since 2015.) One notable big player is Apollo (opens new window). code/ (opens new window) has a list implementations in different languages (Note that it has server libraries for the backend to implement the API, and client libraries for the front end to use the API). There are many implementations of GraphQL. and use SQL language to work with the data). (just like SQL, you cannot "download SQL", you download softwares like MySQL that implemented the SQL language. So you use a library that implemented this language. Originally developed by Facebook, now open-source.
