wasi-fetch

Ergonomic HTTP client for WebAssembly components. Wraps the low-level wasip3 HTTP types behind a reqwest-inspired API, using standard http::Request/http::Response types.

Usage

[dependencies]
wasi-fetch = "0.1"

use wasi_fetch::Client;

// GET
let resp = Client::new().get("https://example.com/api").send().await?;
let status = resp.status();
let body = String::from_utf8(resp.into_body())?;

// POST with JSON
let resp = Client::new()
    .post("https://example.com/api")
    .header("authorization", "Bearer token")
    .json(&serde_json::json!({"key": "value"}))
    .send()
    .await?;

// Low-level: send http::Request directly
let request = http::Request::get("https://example.com")
    .body(vec![])
    .unwrap();
let response = wasi_fetch::send(request).await?;

Features

• http crate types — http::Response<Vec<u8>> return type, http::HeaderMap, http::StatusCode
• Builder API — Client::new().get(url).header(...).json(...).timeout_ms(...).send().await
• Low-level send() — pass an http::Request<Vec<u8>> directly
• Timeout — per-request connect + first-byte timeout

Target

wasm32-wasip2 with nightly Rust toolchain.
