@vyriy/request

Part of Vyriy - a calm architecture toolkit for TypeScript, React, SSR, SSG, APIs, and cloud-ready apps.

Shared request utility for Vyriy projects.

Purpose

This package provides a small wrapper around fetch with timeout handling, retry behavior for retryable failures, and basic response parsing for JSON and text payloads.

Install

With npm:

npm install @vyriy/request

With Yarn:

yarn add @vyriy/request

Usage

Read JSON:

import { request, requestStream } from '@vyriy/request';

const profile = await request<{ id: string; name: string }>('/api/profile');

Read text with custom retry and timeout behavior:

const html = await request<string>('https://example.com', null, {
  retries: 1,
  timeout: 5000,
});

Send JSON with POST:

type CreatedProfile = {
  id: string;
};

const created = await request<CreatedProfile>('/api/profile', {
  method: 'POST',
  headers: {
    'content-type': 'application/json',
  },
  body: JSON.stringify({
    name: 'Ada',
  }),
});

Send authenticated requests:

const projects = await request<Array<{ id: string; name: string }>>('/api/projects', {
  headers: {
    authorization: `Bearer ${token}`,
    accept: 'application/json',
  },
});

Send form data:

const form = new FormData();
form.append('title', 'Draft');
form.append('file', file);

await request('/api/upload', {
  method: 'POST',
  body: form,
});

Use an external abort signal:

const controller = new AbortController();

const pending = request('/api/search', {
  signal: controller.signal,
});

controller.abort();

await pending;

Consume streaming chunks:

const decoder = new TextDecoder();

await requestStream('/api/events', null, {
  onChunk: (chunk) => {
    console.info(decoder.decode(chunk));
  },
});

Get the raw streaming response:

const response = await requestStream('/api/download');
const body = response.body;

API

• request(input, init?, options?) performs a fetch call and returns parsed JSON or text.
• requestStream(input, init?, options?) performs a fetch call and returns the successful Response.
• requestStream(..., { onChunk }) consumes response.body and calls onChunk for each Uint8Array chunk in order.
• init may be null when you want to skip request init and pass options as the third argument.
• options.timeout sets the per-attempt timeout in milliseconds.
• options.retries controls how many retry attempts are allowed after the initial request.
• options.retryDelay sets the base delay in milliseconds between retry attempts.
• options.retryMethods overrides which HTTP methods are allowed to retry.
• options.retryStatuses overrides which HTTP status codes are considered retryable.

For streaming requests, retries happen only before chunk consumption starts. This avoids delivering duplicate chunks to onChunk.
