APIful

APIful provides a unified interface to manage all your API interactions by setting up a client with default fetch options, such as the base API URL and headers. Extensions add a variety of features to the client to match your favorite flavor of API management.

You can use one of the built-in extensions to get started right away, or create your own custom extension to meet your specific needs.

Setup

[!TIP] 📖 Read the documentation

# pnpm
pnpm add -D apiful

# npm
npm i -D apiful

Usage

[!TIP] 📖 Read the documentation

Your First API Client

Create your first API client by initialising it with a base URL and a sample bearer token for authorization:

import { createClient } from 'apiful'

const baseURL = '<your-api-base-url>'
const client = createClient({
  baseURL,
  headers: {
    Authorization: `Bearer ${process.env.API_KEY}`,
  },
})

[!NOTE] The createClient function returns an ApiClient instance that does not yet have a call signature. You will need to add a base extension to the client in order to make API requests. Read on to learn how to do this.

Built-in Extensions

ofetchBuilder import { createClient, ofetchBuilder } from 'apiful' const baseURL = '<your-api-base-url>' const adapter = ofetchBuilder() const api = createClient({ baseURL }).with(adapter) // GET request to <baseURL>/users/1 await api('users/1', { method: 'GET' })	What it does: The ofetchBuilder wraps ofetch to handle API requests.
apiRouterBuilder import { apiRouterBuilder, createClient } from 'apiful' const baseURL = '<your-api-base-url>' const adapter = apiRouterBuilder() const api = createClient({ baseURL }).with(adapter) // GET request to <baseURL>/users/1 await api.users.get(1) // POST request to <baseURL>/users with payload await api.users.post({ name: 'foo' })	What it does: The apiRouterBuilder provides a jQuery-like and Axios-esque API for building and making API requests. It allows you to construct your API calls in a declarative way.
OpenAPIBuilder import { createClient, OpenAPIBuilder } from 'apiful' const baseURL = 'https://petstore3.swagger.io/api/v3' // Pass pre-generated schema type ID to adapter const adapter = OpenAPIBuilder<'petStore'>() const api = createClient({ baseURL }).with(adapter) // Typed parameters and response const response = await api('/user/{username}', { method: 'GET', path: { username: 'user1' }, })	What it does: If your API has an OpenAPI schema, APIful can use it to generate types for you, which the OpenAPIBuilder extension then consumes to provide type-safe API calls. For example, the response returned by the API call on the left is typed as follows: const response: { id?: number username?: string // … } Follow the OpenAPI extension documentation to learn more about how to generate TypeScript definitions from your OpenAPI schema files.

Custom Extensions

Each client can have more than one extension. This means that you can chain with methods to add multiple extensions to your client.

For example, you can add a custom extension to log the default fetch options:

import type { MethodsExtensionBuilder } from 'apiful'

const logExtension = (client => ({
  logDefaults() {
    console.log('Default fetch options:', client.defaultOptions)
  }
})) satisfies MethodsExtensionBuilder

const extendedClient = client
  .with(logExtension)

extendedClient.logDefaults() // { baseURL: '<your-base-url>', headers: { Authorization: 'Bearer <your-bearer-token>' } }

If you have specific requirements that are not covered by the included extensions, you can create your own extensions. Follow the Custom Extensions guide to learn more.
