![]() The best part? Getting started with REST Client is incredibly simple, and I’m going to show you just how easy (and full featured) this plugin is, right here, right now. No longer do we need to exit the IDE to test APIs, because now a plugin exists to do just that: REST Client. Now in the past, in order to test REST APIs before wiring up the UI to accept the data, typically you’d have to either query the API through a terminal’s command line, or use a GUI like Insomnia or Postman (which I actually compared in a previous blog post).īut now, if you use VS Code (and why wouldn’t you, it’s so nice to write code in!) life has just gotten simpler. In laymen’s terms: the data we want exists in some other service or database, and our application queries that service to retrieve the data and use it as we see fit. If you’ve been doing web development for any length of time, you’re probably aware that a lot of our job revolves around data: reading data, writing data, manipulating data and displaying it in the browser in a way that makes sense.Īnd the vast majority of that data is supplied from REST API endpoints: representational state transfer application programming interfaces (what a mouth full □, hence REST API). Send a tokenAuth mutation to obtain the token.Photo by Carlos Muza on Unsplash Web Developers fetch a lot of data In other words, an access token of some sort would be required in the request header of the createArticle mutation. Imagine if we want to run the createArticle mutation to create a new article, the server would require us to be authorized first. ![]() Insomnia provides the ability to extract values from the responses of other requests ( source). If the hotkey Control + Space doesn’t work, use instead. To reference any environment variable, simply press Control/Cmd + Space on your keyboard. Hotkey: Cmd/Ctrl + Eĭo note that the environment is to be filled with JSON format. Like Postman, we could easily set environment variables in Insomnia and use them later on when making our requests.įor instance, we can configure our API’s BASE_URL according to our environment such as Local, Staging or Production and switch to a different environment with ease. Here are some useful tips when using Insomnia. As a result, to use autocomplete on Postman, one would need to import your schema file manually to Postman every time there are new changes made to your schema which can be very cumbersome. Postman as of the date of writing this article does not directly support importing GraphQL schemas via URL directly ( issue). ![]() With the introspection system, GraphQL can provide a way for clients to discover the resources that are available in a GraphQL schema which then allows features like self-documentation and autocompletion to be used by the users. Why not Postman? Lack of support for schema import via URL and autocomplete The goal of this article is to share with you some of the handy tips and tricks that you can use with Insomnia, especially while developing GraphQL APIs, though it works great with REST too. While Postman is the de facto standard for API testing and development, I would like to draw your attention to a fast and easy-to-use alternative to Postman - Insomnia REST Client. Generally, one would use an API client to test APIs in terms of functionality, performance, security, reliability, and the correctness of the responses. If you are developing a set of APIs, chances are you already know Postman - an API Client for API development. ![]()
