Kapeta NodeJS REST Client

This provides a REST client for use with Kapeta.

It wraps the NodeJS fetch API and provides a simple interface for making requests within Kapeta.

The specific REST clients are generated by Kapeta and will extend the RestClient class in this package.

Usage

The RestClient class is not meant to be used directly - you should use the generated subclasses.

They will however all have the same interface which is documented here.

Making requests

Normally you will make a request by calling the generated method on the client - however you can also make a request directly by calling the $create or $execute method on the client directly.

client.$create will return a Request object which you can then modify before sending it with request.call().

client.$execute will send the request immediately.

Headers

You can configure headers on 3 levels which you can see below.

In addition to the withHeader method there are also a few convenience methods for common headers:

• withContentType(contentType:string): Sets the Content-Type header
• withAuthorization(authorization:string): Sets the Authorization header
• withBearerToken(token:string): Sets the Authorization header with a Bearer token

Per request

Sets headers for this request only

const response = await client.someMethodRequest().withHeader('X-Some-Header', 'some-value').call();

Per client

Sets headers for all requests made by this client.

Note the "$" in front of the method name. This is to avoid name collisions with the generated methods.

const client = new SomeClient().$withHeader('X-Some-Header', 'some-value');
const response = await client.someMethod();

Globally:

Sets headers for all requests made by all clients

RestClient.setDefaultHeader('X-Some-Header', 'some-value');
const client = new SomeClient();
const response = await client.someMethod();

Timeouts

To configure the request timeout you have an option to do so on 3 levels:

Per request

const response = await client
    .someMethodRequest()
    .withTimeout(1000) // Set timeout to 1 second
    .call();

Per client

const client = new SomeClient().$withTimeout(1000); // Set timeout to 1 second
const response = await client.someMethod();

Globally:

RestClient.setDefaultTimeout(1000); // Set timeout to 1 second
const client = new SomeClient();
const response = await client.someMethod();
