About

Lemmy is similar to sites like Reddit, Lobste.rs, Raddle, or Hacker News: you subscribe to forums you're interested in, post links and discussions, then vote, and comment on them. Behind the scenes, it is very different; anyone can easily run a server, and all these servers are federated (think email), and connected to the same universe, called the Fediverse.

For a link aggregator, this means a user registered on one server can subscribe to forums on any other server, and can have discussions with users registered elsewhere.

The overall goal is to create an easily self-hostable, decentralized alternative to reddit and other link aggregators, outside of their corporate control and meddling.

Each lemmy server can set its own moderation policy; appointing site-wide admins, and community moderators to keep out the trolls, and foster a healthy, non-toxic environment where all can feel comfortable contributing.

Why's it called Lemmy?

• Lead singer from motorhead.
• The old school video game.
• The furry rodents.

Made with Rust, Actix, Inferno, Typescript and Diesel.

Usage

Production

Docker

Make sure you have both docker and docker-compose installed.

git clone https://github.com/dessalines/lemmy
cd lemmy
./docker_update.sh # This pulls the newest version, builds and runs it

and goto http://localhost:8536

Development

Kubernetes

Requirements

• Local or remote Kubernetes cluster, i.e. minikube
• kubectl
• skaffold

Running

skaffold dev -p lemmy--dev

And goto http://localhost:4444 (automatically proxies to localhost, both if the cluster is local or remote).

It hot-reloads the UI and automatically recompiles the server.

Non-Kubernetes

Requirements

• Rust
• Yarn
• Postgres

Set up Postgres DB

 psql -c "create user rrr with password 'rrr' superuser;" -U postgres
 psql -c 'create database rrr with owner rrr;' -U postgres

Running

git clone https://github.com/dessalines/lemmy
cd lemmy
./install.sh
# For live coding, where both the front and back end, automagically reload on any save, do:
# cd ui && yarn start
# cd server && cargo watch -x run

and goto http://localhost:8536
