Axios SDK Monorepo

Lightweight, modular TypeScript SDK inspired by Axios but designed for modern DApps.

Features

• Lightweight fetch-based engine
• Async/await API
• Request/response interceptors
• JSON auto-parsing
• Configurable instances (Axios.create)
• Plugin system for middleware and crypto signing
• TypeScript-first with shared types

Monorepo Structure

• packages/core - low-level request engine
• packages/client - public SDK API
• packages/crypto - signing plugins (Solana/EVM)
• packages/utils - shared utilities
• packages/types - shared TypeScript types
• packages/examples - Node, Browser, DApp examples

Installation

pnpm install

Building

pnpm build

Running Tests

pnpm test

Quick Usage (Node)

import { Axios } from '@axios/client';

const api = Axios.create({ baseURL: 'https://httpbin.org', timeout: 10000 });
const resp = await api.get('/get');
console.log(resp.data);

Creating Instances

Use Axios.create(config) to create an instance with defaults. Each instance exposes get, post, put, patch, delete, and interceptors.

Writing Plugins

Plugins are simple objects with optional request and response interceptor functions.

api.use({
	request: async (cfg) => {
		// modify and return cfg
		return cfg;
	}
});

Crypto Signing

See @axios/crypto for SolanaSigner and EvmSigner examples which attach an X-Signature header to outgoing requests.

Error Handling

Errors are wrapped in AxiosError (from @axios/types) and include .isAxiosError, .config, .code, and optional .response when available.

DApp Integration

Use @axios/crypto plugins to sign outgoing payloads using wallet signers (Solana signMessage or EVM signMessage). Plugins attach signatures to headers so server-side verification can be performed.
