New APIs should make their best effort to not use header names that can conflict with other applications. However with RFC 6648 they got deprecated. For example, if you were using CSRF tokens, it was a common (but non-standard) way to name them X-Csrf-Token. If you need to set any custom metadata in your headers, it was a best practice to prefix them with X. Headers like this can be information on:Ī list of standardized HTTP headers can be found here. To attach metadata about the payload you are about to send, use HTTP headers.
ELECTRON API BEST PRACTICES FULL
Similarly with Restify: res.status(201).įor a full list, check the list of HTTP status codes #3 – Use HTTP headers to Send Metadata If you are using Express, setting the status code is as easy as res.status(500).send().
5xx, if something went wrong on the API side (like an exception happened).4xx, if the request cannot be fulfilled because of a client error (like requesting a resource that does not exist),.If something goes wrong while serving a request, you must set the correct status code for that in the response:
ELECTRON API BEST PRACTICES PATCH
PATCH /user/:id to modify an existing user record,.POST /user or PUT /user:/id to create a new user,.Speaking of the user’s resources, the routing can look like this: For these operations HTTP already has the adequate toolset: POST, PUT, GET, PATCH or DELETE.Īs a best practice, your API routes should always use nouns as resource identifiers. Imagine, that you are building a Node.js RESTful API for creating, updating, retrieving or deleting users. I hope these best-practices we use at RisingStack can help: #1 – Use HTTP Methods & API Routes Still, while we help our customers to find issues in their applications with Trace, our Node.js monitoring tool we constantly experience that developers have a lot of problems with REST APIs. One of the most popular use-cases for Node.js is to write RESTful APIs using it. REST APIs, including topics like naming your routes, authentication, black-box testing & using proper cache headers for these resources. Node.js is free of locks, so there's no chance to dead-lock any process. In this article we cover best practices for writing Node.js Node.js is an asynchronous event-driven JavaScript runtime and is the most effective when building scalable network applications.
