Get vs Fetch in Supabase (2024)

FAQs

Why use Fetch instead of Get? ›

Simple Data Retrieval: Use GET for straightforward queries where caching and idempotence are beneficial. Complex Operations: Use FETCH when you need to send data (e.g., JSON payloads) or require detailed control over the request.

One of the key advantages of the Fetch API is its promise-based approach. Instead of dealing with event-based callbacks like in XMLHttpRequest, the Fetch API returns a Promise, allowing developers to chain subsequent operations using . then() and . catch() methods.

The Fetch API provides an interface for fetching resources (including across the network). It is a more powerful and flexible replacement for XMLHttpRequest .

Fetch API comes with a fetch () method that allows you to fetch data from all sorts of different places and work with the data fetched. It allows you to make an HTTP request, i.e., either a GET request (for getting data) or POST request (for posting data).

When comparing Git pull vs fetch, Git fetch is a safer alternative because it pulls in all the commits from your remote but doesn't make any changes to your local files. On the other hand, Git pull is faster as you're performing multiple actions in one – a better bang for your buck.

Automatic transformation of response data is not happening in fetch() API and we have to do it manually. Response timeout configuration in fetch() API is difficult to implement. fetch() doesn't provide a way to intercept requests by default, and it's bit difficult to implement.

Axios will automatically transforms the server's response data, while with Fetch, you need to call the response. json method to parse the data into a JavaScript object. Furthermore, Axios delivers the data response within the data object, whereas Fetch allows the final data to be stored in any variable.

Fetch API allows us to get data from a local or remote server via a RESTful API. It is a promise-based asynchronous API where we can either await it or use promise chaining to get the response. This is where XMLHttpRequest and the Fetch API differ.

A fetch() promise only rejects when the request fails, for example, because of a badly-formed request URL or a network error. A fetch() promise does not reject if the server responds with HTTP status codes that indicate errors ( 404 , 504 , etc.).

Can a get request have a body? ›

The HTTP/1.1 specification (RFC 7230) does allow for the inclusion of a request body in GET requests, although it is generally not recommended. While technically feasible, attaching a body to a GET request goes against the principle of using GET for safely retrieving data without modifying server resources.

A fetch() method can be used with many type of requests such as POST, GET, PUT and DELETE.

The Fetch API provides a JavaScript interface for accessing and manipulating parts of the protocol, such as requests and responses. It also provides a global fetch() method that provides an easy, logical way to fetch resources asynchronously across the network.

Fetch's solution allows residents to control their delivery service from the comfort of their couch, removing communities from package management entirely.

Axios provides the data in the response object, while fetch() provides the response object itself, which contains other information such as status, headers, and url. Axios handles errors in the catch block, while fetch() only rejects the promise if there is a network error, not if the response has an error status.

Git clone creates a copy of the code in your local machine. Git fetch , fetches code from git to your local repository but will not update it. Once Git merge is executed the code is updated.
