As a developer, it’s important to have efficient tools for testing and debugging APIs. Alongside well-known tools like Postman<\/em><\/strong> or Insomnia<\/em>, Visual Studio Code offers a useful extension called “REST Client<\/em><\/strong>” that provides some interesting advantages.<\/p>\n\n\n\n

Integrated Tool<\/span><\/h5>\n\n\n\n

The biggest benefit of the REST Client extension is that it is integrated directly into Visual Studio Code. This means that we can create and test our API requests right within our code editor, without having to switch between different applications. This increases efficiency and productivity, as we have everything in one place.<\/p>\n\n\n\n

before you were probably using some tool like\u00a0Postman\u00a0<\/strong><\/a>or\u00a0Insomnia<\/strong><\/a>. But that mean you should leave your Visual Studio Code instance and\u00a0open another tool<\/strong>, install it if you do not have it, configure,\u00a0SO TIME WASTING AND CONSUMING<\/em><\/strong>.<\/p>\n\n\n\n

Now, we can just\u00a0install extension REST Client<\/strong>\u00a0inside our\u00a0VS Code<\/strong>\u00a0and then we\u00a0can define our HTTP request within .http file<\/strong>\u00a0and test our code without using some other external code.<\/p>\n\n\n\n

Syntax Highlighting and Autocomplete<\/span><\/h5>\n\n\n\n

The REST Client extension provides syntax highlighting for creating API requests. This makes the code more readable and organized. Additionally, the extension supports autocomplete, which significantly simplifies the process of writing API requests.<\/p>\n\n\n\n

Local Storage of Requests<\/span><\/h5>\n\n\n\n

Another useful feature is the ability to store API requests locally in our work environment. This way, we can easily retrieve and reuse our frequently used requests, without having to rewrite them every time.<\/p>\n\n\n\n

Easy API Testing<\/span><\/h5>\n\n\n\n

With the REST Client extension, we can test API requests directly from our code editor. We only need to create a .http file <\/em><\/strong>and define our requests within it. Then, we can execute the requests with a single click and view the results right in the editor.<\/p>\n\n\n\n

Usage Examples<\/h4>\n\n\n\n

Let”s go to our Extensions in VS Code and install it or download it from here:\u00a0https:\/\/marketplace.visualstudio.com\/items?itemName=humao.rest-client<\/a><\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Now to show you how it works we will create simple\u00a0Express.js<\/strong>\u00a0endpoint and test it directly from VS Code.<\/p>\n\n\n\n

So we will have one file,\u00a0index.js<\/strong>\u00a0and this in memory list and one GET endpoint.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Now we should create some file with .http extension. So we will create course.http file <\/em><\/strong>and we will write just two lines of code to test our GET method.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

<\/p>\n\n\n\n

PS: <\/strong>replace the URL with your localhost address.<\/em><\/p>\n\n\n\n

Now to test this, we can run our application trought the command : node index.js<\/em><\/strong><\/p>\n\n\n\n

And while our backend is spinning, we can test our endpoint directly from .http file. <\/p>\n\n\n\n

As you can see if we have installed REST client <\/em><\/strong>extension, in .http file<\/em><\/strong> we can see button\u00a0Send Request<\/em><\/strong>.<\/p>\n\n\n\n

If we execute this action, we should get following output in VS Code.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

And that’s it, simple, isn\u2019t it.\u00a0Without leaving our favorite IDE<\/strong>, just to see if everything is working as expected.<\/p>\n\n\n\n

We can also add a couple of more request. if we want (for example) to test also some POST request, our .http file can look something like this.<\/p>\n\n\n\n

Summary<\/span><\/h4>\n\n\n\n
1- Sending a GET request to an API:<\/h5>\n\n\n\n
GET https:\/\/api.example.com\/users\r<\/code><\/pre>\n\n\n\n
2-Sending a POST request with JSON data:<\/h5>\n\n\n\n
POST https:\/\/api.example.com\/users\r\nContent-Type: application\/json\r\n\r\n{\r\n    \"name\": \"John Doe\",\r\n    \"email\": \"john.doe@example.com\"\r\n}\r<\/code><\/pre>\n\n\n\n
3- Authentication with an API key:<\/h5>\n\n\n\n
GET https:\/\/api.example.com\/data\r\nX-API-Key: your_api_key_here\r<\/code><\/pre>\n\n\n\n
4-Bundling multiple requests in a single file:<\/h5>\n\n\n\n
# Get user list\r\nGET https:\/\/api.example.com\/users\r\n\r\n###\r\n\r\n# Create a new user\r\nPOST https:\/\/api.example.com\/users\r\nContent-Type: application\/json\r\n\r\n{\r\n    \"name\": \"Jane Doe\",\r\n    \"email\": \"jane.doe@example.com\"\r\n}\r\n<\/code><\/pre>\n\n\n\n
