And you must\u2019ve come across them if you ever tried building a news app or dashboard that needs \u201clive\u201d news, prices, or updates. However, these two terms are different, and picking the wrong one for your project can leave you with a slow app, a costly server bill, or both.<\/p>\n

In this guide, we have broken down what each one actually is, how they differ, and which one you should use depending on what you are building. Especially if real-time news<\/a><\/b> is part of your product.[\/vc_column_text][vc_column_text]\n

What is a Streaming API?<\/b><\/h2>\n

A Streaming API<\/a><\/b> is a general term for any API that pushes data to you continuously, instead of making you ask for it over and over again. With a streaming API, you open a connection once, instead of sending a request and waiting for one response. The server keeps sending new data through that same connection as it becomes available.<\/p>\n

You can think of a streaming API as subscribing to a newsletter instead of checking a website regularly for updates. By setting up a subscription once, you get new updates as they arrive.<\/p>\n

Streaming APIs can be built on top of several technologies, and WebSocket is one of them, but so are Server-Sent Events (SSE) and HTTP long-polling<\/a><\/b>. So \u201cstreaming API\u201d describes the behaviour (continuous, real-time delivery), not a specific delivery method.[\/vc_column_text][vc_column_text]\n

What is a WebSocket?<\/b><\/h2>\n

A WebSocket is a specific protocol for communication between two systems over a single, persistent, two-way connection. Once a WebSocket connection is established between a client and a server, both sides can send messages at any time without starting a new request each time.<\/p>\n

This is different from the traditional web request-response model, where your browser or app has to ask for something to get an answer. With WebSocket, the \u201cconversation\u201d stays open, and either side can speak whenever there\u2019s something new to say.<\/p>\n

So, a streaming API is a concept for getting continuous updates. WebSocket is one of the technologies commonly used to deliver on that concept.[\/vc_column_text][vc_column_text]\n
