Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

bitspace

Unichains, batteries included.

BitSpace is a lightweight server that provides remote access to Unichains and a BitSwarm instance. It exposes a simple RPC interface that can be accessed with the Bitspace client for Node.js.

The RPC API's designed to be minimal, maintaining parity with Unichain and the @web4/chainstore-networker but with few extras.

Features include:

  • A RemoteChainstore interface for creating namespaced Chainstore instances.
  • A RemoteNetworker interface for managing BitSwarm DHT connections. Supports stream-level extensions.
  • A RemoteUnichain interface that feels exactly like normal ol' Unichain, with few exceptions. Extensions included.

Already using the BitDrive daemon?

With Bitspace, most of the BitDrive daemon's functionality has been moved into "userland" -- instead of providing remote access to BitDrives, the regular bitdrives module can be used with remote Unichains.

If you're currently using the BitDrive daemon with FUSE and/or the daemon CLI, take a look at the upgrade instructions in bitdrive-cli, which is our new BitDrive companion service for handling FUSE/CLI alongside BitSpace.

Note: The first time you run Bitspace, it will detect your old BitDrive daemon installation and do an automatic migration. You can postpone the migration by starting the server with the --no-migrate flag (bitspace --no-migrate).

Installation

npm i bitspace -g

Getting Started

When installed globally, you can use the bitspace CLI tool to start the server:

❯ bitspace --no-migrate  // Starts the server without performing the BitDrive daemon migration

The bitspace command supports the following flags:

--bootstrap   // BitSwarm bootstrapping options (see BitSwarm docs).
--host        // Host to bind to.
--port        // Port to bind to (if specified, will use TCP).
--memory-only // Run in memory-only mode.
--no-announce // Never announce topics on the DHT.
--no-migrate  // Do not attempt to migrate the BitDrive daemon's storage to Bitspace.
--repl        // Start the server with a debugging REPL.

By default, Bitspace binds to a UNIX domain socket (or named pipe on Windows) at ~/.bitspace/bitspace.sock.

Once the server's started, you can use the client to create and manage remote Unichains. If you'd like the use the BitDrive CLI, check out the @web4/bitdrive docs.

API

To work with Bitspace, you'll probably want to start with the Node.js client library. The README over there provides detailed API info.

Simulator

Bitspace includes a "simulator" that can be used to create one-off Bitspace instances, which can be used for testing.

const simulator = require('bitspace/simulator')
// client is a BitspaceClient, server is a BitspaceServer
const { client, server, cleanup } = await simulator()
