api-wizard/instance.js

A powerful TypeScript wrapper for native Fetch API with token management, interceptors, and type-safe HTTP requests

import { FetchClientImpl } from "./fetchClient";
import { InterceptedFetchClient } from "./interceptor";
import { fetchRequestConfig, createFetchDefaults } from "./config";
function instance(baseUrl, option) {
    const fetchDefaults = createFetchDefaults({
        baseUrl,
        option,
    });
    // 인터셉터가 있으면 InterceptedFetchClient, 없으면 기본 FetchClientImpl 사용
    const fetchInstance = option?.interceptor
        ? new InterceptedFetchClient({
            baseURL: fetchDefaults.baseURL,
            headers: fetchDefaults.headers,
            requestConfig: {
                credentials: fetchDefaults.credentials,
                ...fetchRequestConfig
            },
            interceptor: option.interceptor
        })
        : new FetchClientImpl({
            baseURL: fetchDefaults.baseURL,
            headers: fetchDefaults.headers,
            requestConfig: {
                credentials: fetchDefaults.credentials,
                ...fetchRequestConfig
            }
        });
    return {
        get: (url, config) => fetchInstance.get(url, { ...fetchRequestConfig, ...config }),
        post: (url, data, config) => fetchInstance.post(url, data, { ...fetchRequestConfig, ...config }),
        put: (url, data, config) => fetchInstance.put(url, data, { ...fetchRequestConfig, ...config }),
        patch: (url, data, config) => fetchInstance.patch(url, data, { ...fetchRequestConfig, ...config }),
        delete: (url, config) => fetchInstance.delete(url, { ...fetchRequestConfig, ...config }),
        getInstance: () => fetchInstance
    };
