Startup parameters

Building

From within the bcr-ebill-wasm crate.

Development build:

wasm-pack build --dev --target web

Release build:

wasm-pack build --target web

Artifacts land in crates/bcr-ebill-wasm/pkg, including generated TypeScript bindings.

Running

Serve the crate directory with any static HTTP server:

http-server -c-1 .

Then open http://localhost:8080/. The repository ships index.html and main.js as a playground for exercising the built module.

Starting the API

The module is initialised with a config object:

import * as wasm from '../pkg/bcr_ebill_wasm.js';

async function start() {
    let config = {
        bitcoin_network: "testnet",
        nostr_relays: ["wss://relay.wildcat0.clowder-dev.minibill.tech"],
        surreal_db_connection: "indxdb://default",
        job_runner_initial_delay_seconds: 1,
        job_runner_check_interval_seconds: 60,
    };
    // ...
}

See main.js in the crate for fuller examples.

Resetting local state

In the browser, SurrealDB is backed by IndexedDB. There are three ways to get back to a blank slate:

• clear IndexedDB in the browser's developer tools, under Storage;
• open the app in a different browser;
• open it in a private window.

Which network you are on

bitcoin_network decides the network character in every identifier the instance creates, so a testnet identity cannot be mistaken for a mainnet one. Switching the setting does not carry data across.
