Install the WAX TypeScript SDK using your preferred package manager.

​
Install the package

npm install @hiveio/wax
The package includes TypeScript definitions and works in all JavaScript/TypeScript environments.

​
Requirements

Your environment needs:
  • Node.js 20.11+ or 21.2+ (for Node.js applications)
  • Modern browsers with WebAssembly support (Chrome 57+, Firefox 52+, Safari 11+, Edge 16+)
  • Build tools configured for WASM (see framework-specific guides below)

​
Basic setup

Import and initialize the SDK: 
import { createHiveChain } from "@hiveio/wax";

const chain = await createHiveChain();
console.log(chain.getVersion());
For offline operations only: 
import { createWaxFoundation } from "@hiveio/wax";

const wax = await createWaxFoundation();
console.log(wax.getVersion());

​
Configuration options

​
Chain configuration

Customize the chain connection: 
import { createHiveChain } from "@hiveio/wax";

const chain = await createHiveChain({
  chainId: "beeab0de00000000000000000000000000000000000000000000000000000000", // Mainnet (default)
  apiEndpoint: "https://api.hive.blog", // API node URL (default)
  restApiEndpoint: "https://api.syncad.com", // REST API URL (default)
  apiTimeout: 2000, // Request timeout in milliseconds (default: 2000)
  waxApiCaller: "my-app/1.0.0" // Optional identifier for your application
});

​
WASM location

Specify a custom WASM file location: 
import { createWaxFoundation } from "@hiveio/wax";

const wax = await createWaxFoundation({
  wasmLocation: "/path/to/wax.common.wasm"
});
For bundlers, import the WASM file: 
import wasmUrl from '@hiveio/wax/lib/build_wasm/wax.common.wasm?url';
import { createWaxFoundation } from "@hiveio/wax";

const wax = await createWaxFoundation({ wasmLocation: wasmUrl });

​
Framework-specific setup

​
Vite

Vite handles WASM automatically. No additional configuration needed: 
import { createWaxFoundation } from "@hiveio/wax";

const wax = await createWaxFoundation();

​
Webpack 5

Enable WASM support in webpack.config.js: 
module.exports = {
  experiments: {
    asyncWebAssembly: true
  }
};

​
Next.js

For Next.js 13+ with App Router, add to next.config.js: 
/** @type {import('next').NextConfig} */
const nextConfig = {
  webpack: (config) => {
    config.experiments = {
      ...config.experiments,
      asyncWebAssembly: true
    };
    return config;
  }
};

module.exports = nextConfig;
Import WAX in client components: 
"use client";

import { createWaxFoundation } from "@hiveio/wax";
import { useEffect, useState } from "react";

export default function MyComponent() {
  const [version, setVersion] = useState("");

  useEffect(() => {
    createWaxFoundation().then((wax) => {
      setVersion(wax.getVersion());
    });
  }, []);

  return <div>WAX version: {version}</div>;
}

​
Nuxt

WAX supports both SSR and client-side rendering in Nuxt: 
<script setup>
import { createWaxFoundation } from "@hiveio/wax";
import { ref } from 'vue';

const version = ref('');

if (process.server) {
  // Server-side initialization
  const wax = await createWaxFoundation();
  version.value = wax.getVersion();
} else {
  // Client-side initialization
  onBeforeMount(async () => {
    const wax = await createWaxFoundation();
    version.value = wax.getVersion();
  });
}
</script>

<template>
  <div>{{ version }}</div>
</template>

​
Node.js

WAX works in Node.js without additional configuration: 
import { createHiveChain } from "@hiveio/wax";

const chain = await createHiveChain();
const props = await chain.api.database_api.get_dynamic_global_properties({});

console.log(`Head block: ${props.head_block_number}`);
Make sure your package.json includes: 
{
  "type": "module"
}

​
TypeScript configuration

For optimal TypeScript support, ensure your tsconfig.json includes: 
{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "lib": ["ES2020", "DOM"],
    "strict": true
  }
}

​
Verify installation

Create a test file to verify everything works:
test.ts
import { createWaxFoundation } from "@hiveio/wax";

const wax = await createWaxFoundation();
console.log(`WAX version: ${wax.getVersion()}`);
console.log(`Chain ID: ${wax.chainId}`);
console.log(`Address prefix: ${wax.addressPrefix}`);
Run it: 
node test.ts
Expected output: 
WAX version: 1.27.x.x
Chain ID: beeab0de00000000000000000000000000000000000000000000000000000000
Address prefix: STM

​
Installing signer packages

For transaction signing, install a signer package: 
npm install @hiveio/wax-signers-beekeeper
See the transaction signing documentation for usage details.

​
Troubleshooting

​
WASM loading errors

If you see WASM loading errors, verify:
  1. Your bundler supports WebAssembly
  2. The WASM file path is correct
  3. Your server serves .wasm files with the correct MIME type (application/wasm)

​
Module resolution errors

For TypeScript errors about module resolution:
  1. Ensure moduleResolution is set to "bundler" or "node16"
  2. Check that @hiveio/wax is installed in node_modules
  3. Restart your TypeScript language server

​
Bundle size issues

The WASM module is approximately 1.5 MB. For optimal loading:
  1. Enable compression on your web server (gzip or brotli)
  2. Use code splitting to load WAX only when needed
  3. Consider using a CDN for the WASM file
