🥅 Koj Svelte API Client

This repository contains Koj's Fetch API-powered client for interacting with our API. It is very opinionated, so usage is only recommended in Koj's Svelte projects.

| | Status | | - | - | | Build | | | Health | | | PRs | |

⭐️ Features

• Wrapper around the native Fetch API (95%+ support)
• Tracks logged in users and their permissions
• Authorization helper can based on logged in scopes
• Built-in refreshing expired access tokens before requests
• Response caching in IndexedDB or local storage
• Error handling (text responses from error codes)
• Supports different request/responses:
  • Responses can be JSON or Blob objects
  • Requests can be JSON or FormData

💻 Getting started

Install the dependency from npm:

npm install @koj/svelte-api-client

Import the api method and use it like so:

import { api } from "@koj/svelte-api-client";
import type { User } from "@koj/types";

let user: User | undefined = undefined;
const getUser = async () => {
  user = await api<User>({
    method: "GET",
    url: "/users/12345",
    onCachedResponse: (data) => (user = data),
  });
};

In the above example, the api method expects a type parameter which determines its response time. Note that JSON responses are automatically parsed. The onCachedResponse function is used to get a "faster" responses from a client side-stored cache, using the stale-while-revalidate pattern.
