Installation

With npm

npm install @fluencelabs/fluence

With yarn

yarn add @fluencelabs/fluence

Getting started

Pick a node to connect to the Fluence network. The easiest way to do so is by using fluence-network-environment package

import { dev } from '@fluencelabs/fluence-network-environment';

export const relayNode = dev[0];

Initialize client

import { createClient, FluenceClient } from '@fluencelabs/fluence';

const client = await createClient(relayNode);

Respond to service function calls

subscribeToEvent(client, 'helloService', 'helloFunction', (args) => {
    const [networkInfo] = args;
    console.log(networkInfo);
});

Make a particle

const particle = new Particle(
    `
    (seq
        (call myRelay ("peer" "identify") [] result)
        (call %init_peer_id% ("helloService" "helloFunction") [result])
    )`,
    {
        myRelay: client.relayPeerId,
    },
);

Send it to the network

await sendParticle(client, particle);

Observe the result in browser console

{
    "external_addresses": ["/ip4/1.2.3.4/tcp/7777", "/dns4/dev.fluence.dev/tcp/19002"]
}

Running tests

Tests are split into unit and integration categories. By default integration tests require a locally running Fluence node with 4310 port open for ws connections. The dependency can be started with docker

 docker run --rm -e RUST_LOG="info" -p 1210:1210 -p 4310:4310 fluencelabs/fluence:freeze -t 1210 -w 4310 -k gKdiCSUr1TFGFEgu2t8Ch1XEUsrN5A2UfBLjSZvfci9SPR3NvZpACfcpPGC3eY4zma1pk7UvYv5zb1VjvPHwCjj

To run all tests in interactive mode

npm run test

To run only unit tests

npm run test:unit

To run only integration tests

npm run test:unit

To run all tests

npm run test:all
