Zling Messaging App

What is Zling?

Zling is a guild-channel based messaging application meant for everyone - from a small friend group or gaming community to a large corporate messaging hive. Zling is built on robust and emerging web technologies to remain usable and deployable anywhere you want, with as much control over your data as you want. Controlling bloat and tuning performance is as much a priority as security and privacy.

Zling puts an emphasis on being software before being a service. Anyone can run Zling in the way they want and not have to associate themselves with our branding. We're not here to tell you how you should run your chat platform.

What is Zvelte?

Zvelte is the official web client for the Zling messaging application. You can use Zvelte on any modern browser that supports JavaScript and WebRTC (for voice & video chat).

Zvelte is written in Svelte (duh!), one of the most admired and desired web frameworks of StackOverflow's 2023 developer survey. We chose Svelte because it is lightweight (~6.7kB), performant and great for developer experience.

Zvelte should maintain full API coverage of the Zling API, and remain a first-class application when developing components of Zling. This is one of the main apps that users of Zling interact with.

Quickstart

🚧 Zling and Zvelte are currently under development, and do not have a stable release out yet. You are free to self-host the Zling API Server and this app yourself.

Star and watch this repository if you want to stay updated!

Set up build environment

We prefer to use Bun as a package manager because it's fast. Linux is recommended for a development and building OS as it simplifies installing a lot of dependencies.

1. Install Bun

See Bun's Installation Guide. You can also use a different package manager like npm or yarn, but Bun is strongly recommended.

# check if it works
$ bun --version
1.0.7

2. Install Packages

This installs some needed JS development libraries. Should take about a second to finish...

$ bun install

bun install v1.0.7 (b0393fba)
