In3-wasm NPM | npm.io

Incubed client as WASM

Installing

This client uses the in3-core sources compiled to wasm. The wasm is included into the js-file wich makes it easier to include the data. This module has no dependencies! All it needs is included inta a wasm of about 300kB.

Installing incubed is as easy as installing any other module:

npm install --save in3-wasm

Documentation

The complete documentation can be found https://in3.readthedocs.io/en/develop/ .

In case you want to run incubed within a react native app, you might face issues because wasm is not supported there yet. In this case you can use in3-asmjs, which has the same API, but runs on pure javascript (a bit slower and bigger, but full support everywhere).

Using web3

// import in3-Module
import In3Client from 'in3-wasm'
import * as web3 from 'web3'

const IN3Client c = new IN3Client({
    proof              : 'standard',
    signatureCount     : 1,
    chainId            : 'mainnet',
    replaceLatestBlock : 10
 })

// use the In3Client as Http-Provider
const web3 = new Web3(c)

(async () => {

    // use the web3
    const block = await web.eth.getBlockByNumber('latest')

})().catch(console.error);

Without web3 (Direct API)

Incubed includes a light API, allowinng not only to use all RPC-Methods in a typesafe way, but also to sign transactions and call funnctions of a contract without the web3-library.

For more details see the API-Doc

// import in3-Module
import In3Client from 'in3-wasm'

// use the In3Client
const in3 = new In3Client({
    proof              : 'standard',
    signatureCount     : 1,
    chainId            : 'mainnet',
    replaceLatestBlock : 10
})

(async () => {

    // use the incubed directly
    const block = await in3.eth.getBlockByNumber('latest')

})().catch(console.error);
