fetch to xior
xior use the native fetch API, offering several advantages:
axios?While popular and convenient, Axios currently lacks native edge runtime support (see: https://github.com/axios/axios/issues/5523). This can be an issue for specific use cases like Next.js serverless functions and middleware files, where fetch offers built-in caching and revalidation mechanisms (see: https://nextjs.org/docs/app/api-reference/functions/fetch).
While you can certainly create your own wrapper library around fetch, xior offers a pre-built solution with a familiar API, plugin support for extensibility, and potentially a more streamlined development experience.
# npm
npm install xior
# pnpm
pnpm add xior
# bun
bun add xior
# yarn
yarn add xior
import xior from 'xior';
export const xiorInstance = xior.create({
baseURL: 'https://apiexampledomian.com/api',
headers: {
// put your common custom headers here
},
});
GET
HEADmethod is same usage withGET
async function run() {
const { data } = await xiorInstance.get('/');
// with params
const { data: data2 } = await xiorInstance.get('/', { params: { a: 1, b: 2 } });
// with headers
const { data: data3 } = await xiorInstance.get('/', {
params: { a: 1, b: 2 },
headers: {
'content-type': 'application/x-www-form-urlencoded',
},
});
// types
const { data: data4 } = await xiorInstance.get<{ field1: string; field2: number }>('/');
}
POST
DELETE/PUT/PATCH/OPTIONSmethods are same usage withPOST
async function run() {
const { data: data3 } = await xiorInstance.post<{ field1: string; field2: number }>(
'/',
{ a: 1, b: '2' },
{
params: { id: 1 },
headers: {
'content-type': 'application/json',
},
}
);
}
xior supports file uploads using the FormData API and provides an optional 'xior/plugins/progress' plugin for simulating upload progress, usage similar to Axios.
import Xior from 'xior';
import uploadDownloadProgressPlugin from 'xior/plugins/progress';
const http = Xior.create({});
http.plugins.use(
uploadDownloadProgressPlugin({
progressDuration: 5 * 1000,
})
);
const formData = FormData();
formData.append('file', fileObject);
formData.append('field1', 'val1');
formData.append('field2', 'val2');
http.post('/upload', formData, {
onUploadProgress(e) {
console.log(`Upload progress: ${e.progress}%`);
},
// progressDuration: 10 * 1000
});
xior supports interceptors similar to Axios, allowing you to modify requests and handle responses programmatically.
Request inteceptors:
import xior, { merge } from 'xior';
const http = xior.create({
// ...options
});
http.inteceptors.request.use((config) => {
const token = localStorage.getItem('REQUEST_TOKEN');
if (!token) return config;
return merge(config, {
headers: {
Authorization: `Bearer ${token}`,
},
});
});
// One more inteceptor for request
http.inteceptors.request.use((config) => {
return config;
});
Response inteceptors:
import xior, { merge } from 'xior';
const http = xior.create({});
http.inteceptors.response.use(
(result) => {
const { data, request: config, response: originalResponse } = result;
return result;
},
async (error) => {
if (error?.response?.status === 401) {
localStorage.removeItem('REQUEST_TOKEN');
}
}
);
Timeout:
import xior from 'xior';
const instance = xior.create({
timeout: 120 * 1000, // set default timeout
});
await instance.post(
'http://httpbin.org',
{
a: 1,
b: 2,
},
{
timeout: 60 * 1000, // override default timeout 120 * 1000
}
);
Cancel request:
import xior from 'xior';
const instance = xior.create();
const controller = new AbortController();
xiorInstance.get('http://httpbin.org', { signal: controller.signal }).then((res) => {
console.log(res.data);
});
class CancelRequestError extends Error {}
controller.abort(new CancelRequestError()); // abort request with custom error
xior offers a variety of built-in plugins to enhance its functionality:
Usage:
import xior from 'xior';
import errorRetryPlugin from 'xior/plugins/error-retry';
import throttlePlugin from 'xior/plugins/throttle';
import cachePlugin from 'xior/plugins/cache';
import uploadDownloadProgressPlugin from 'xior/plugins/progress';
const http = xior.create();
http.plugins.use(errorRetryPlugin());
http.plugins.use(throttlePlugin());
http.plugins.use(cachePlugin());
http.plugins.use(uploadDownloadProgressPlugin());
Retry the failed request with special times
API:
function errorRetryPlugin(options: {
retryTimes?: number;
retryInterval?: number;
enableRetry?: boolean | (error: Xiorconfig, error: XiorRequestConfig) => boolean;
}): XiorPlugin;
The options object:
| Param | Type | Default value | Description |
|---|---|---|---|
| retryTimes | number | 2 | Set the retry times for failed request |
| retryInterval | number | 3000 | After first time retry, the next retries interval time, default interval is 3 seconds |
| enableRetry | boolean | ((config: Xiorconfig, error: XiorRequestConfig) => boolean) | (config, error) => config.method === 'GET' | Default only retry if GET request error and retryTimes > 0 |
Basic usage:
import xior from 'xior';
import errorRetryPlugin from 'xior/plugins/error-retry';
const http = xior.create();
http.plugins.use(
errorRetryPlugin({
retryTimes: 3,
retryInterval: 3000,
})
);
// if request error, max retry 3 times until success
http.get('/api1');
// if request error, will not retry, because `retryTimes: 0`
http.get('/api2', { retryTimes: 0 });
// if POST request error, will not retry
http.post('/api1');
// Use `enableRetry: true` to support post method, max retry 5 times until success
http.post('/api1', null, { retryTimes: 5, enableRetry: true });
Throttle GET requests(or custom) most once per threshold milliseconds, filter repeat requests in certain time.
API:
function throttleRequestPlugin(options: {
/** threshold in milliseconds, default: 1000ms */
threshold?: number;
/**
* check if we need enable throttle, default only `GET` method enable
*/
enableThrottle?: boolean | ((config?: XiorRequestConfig) => boolean);
throttleCache?: ICacheLike<RecordedCache>;
}): XiorPlugin;
The options object:
You can override default value in each request's own config (Except
throttleCache)
| Param | Type | Default value | Description |
|---|---|---|---|
| threshold | number | 1000 | The number of milliseconds to throttle request invocations to |
| enableThrottle | boolean | ((config: Xiorconfig) => boolean) | (config) => config.method === 'GET' | Default only enabled in GET request |
| throttleCache | CacheLike | lru(10) | CacheLike instance that will be used for storing throttled requests, use tiny-lru module |
Basic usage:
import xior from 'xior';
import throttlePlugin from 'xior/plugins/throttle';
const http = xior.create();
http.plugins.use(throttlePlugin());
http.get('/'); // make real http request
http.get('/'); // response from cache
http.get('/'); // response from cache
http.post('/'); // make real http request
http.post('/'); // make real http request
http.post('/'); // make real http request
http.post('/', null, {
enableThrottle: true,
}); // make real http request
http.post('/', null, {
enableThrottle: true,
}); // response from cache
http.post('/', null, {
enableThrottle: true,
}); // response from cache
Makes xior cacheable
Good to know: Next.js already support cache for fetch in server side. More detail
API:
function cachePlugin(options: {
enableCache?: boolean | ((config?: XiorRequestConfig) => boolean);
defaultCache?: ICacheLike<XiorPromise>;
}): XiorPlugin;
The options object:
| Param | Type | Default value | Description |
|---|---|---|---|
| enableCache | boolean | ((config: Xiorconfig) => boolean) | (config) => config.method === 'GET' | Default only enabled in GET request |
| defaultCache | CacheLike | lru(100, 1000*60*5) | will used for storing requests by default, except you define a custom Cache with your request config, use tiny-lru module |
Basic usage:
import xior from 'xior';
import cachePlugin from 'xior/plugins/cache';
const http = xior.create();
http.plugins.use(cachePlugin());
http.get('/users'); // make real http request
http.get('/users'); // get cache from previous request
http.get('/users', { enableCache: false }); // disable cache manually and the the real http request
http.post('/users'); // default no cache for post
// enable cache manually in post request
http.post('/users', { enableCache: true }); // make real http request
http.post('/users', { enableCache: true }); // get cache from previous request
Advanced:
import xior from 'xior';
import cachePlugin from 'xior/plugins/cache';
import { lru } from 'tiny-lru';
const http = xior.create({
baseURL: 'https://example-domain.com/api',
headers: { 'Cache-Control': 'no-cache' },
});
http.plugins.use(
cachePlugin({
// disable the default cache
enableCache: false,
})
);
http.get('/users', { enableCache: true }); // manually enable cache for this request
http.get('/users', { enableCache: true }); // get cache from previous request
const cacheA = lru(100);
// a actual request made and cached due to force update configured
http.get('/users', { enableCache: true, defaultCache: cacheA, forceUpdate: true });
Enable upload and download progress like axios, but the progress is simulated, This means it doesn't represent the actual progress but offers a user experience similar to libraries like axios.
API:
function progressPlugin(options: {
/** default: 5*1000 ms */
progressDuration?: number;
}): XiorPlugin;
The options object:
| Param | Type | Default value | Description |
|---|---|---|---|
| progressDuration | number | 5000 | The upload or download progress grow to 99% duration |
Basic usage:
import xior from 'xior';
import uploadDownloadProgressPlugin from 'xior/plugins/progress';
const http = xior.create({});
http.plugins.use(uploadDownloadProgressPlugin());
const formData = FormData();
formData.append('file', fileObject);
formData.append('field1', 'val1');
formData.append('field2', 'val2');
http.post('/upload', formData, {
// simulate upload progress to 99% in 10 seconds, default is 5 seconds
progressDuration: 10 * 1000,
onUploadProgress(e) {
console.log(`Upload progress: ${e.progress}%`);
},
// onDownloadProgress(e) {
// console.log(`Download progress: ${e.progress}%`);
// },
});
xior let you easily to create custom plugins.
Here are examples:
import xior from 'xior';
const instance = xior.create();
instance.plugins.use(function logPlugin(adapter) {
return async (config) => {
const start = Date.now();
const res = await adapter(config);
console.log('%s %s %s take %sms', config.method, config.url, res.status, Date.now() - start);
return res;
};
});
Check src/plugins
xior has built-in helper functions, may useful for you:
import lru from 'tiny-lru';
import {
encodeParams,
merge as deepMerge,
delay as sleep,
buildSortedURL,
isAbsoluteURL,
} from 'xior';
xior frequently asked questions.
axios?No, but xior offers a similar API like axios: axios.create / axios.interceptors / .get/post/put/patch/delete/head/options.
Yes, xior works anywhere where the native fetch API is supported.
Even if the environment doesn't support fetch, you can use a fetch polyfill like for older browsers.
'stream', 'document', 'arraybuffer', or 'blob'?To handle such responses, use the responseType: 'stream' option in your request:
import xior from 'xior';
const http = xior.create({ baseURL });
const { response } = await http.post<{ file: any; body: Record<string, string> }>(
'/stream/10',
null,
{ responseType: 'stream' }
);
const reader = response.body!.getReader();
let chunk;
for await (chunk of readChunks(reader)) {
console.log(`received chunk of size ${chunk.length}`);
}
You can use a polyfill for the fetch API. Check the file src/tests/polyfill.test.ts for a potential example.
The original name axior was unavailable on npm, so when removed the "a": axior.
