A nostr relay bouncer.
Bostr is an nostr relay aggregator proxy that acts like a regular nostr relay. It connects to multiple configured relays to exchange data (events). This project purpose is saving mobile user's bandwidth when using nostr.
Nostr relays is a bunch of dummy servers that store user events. Normally nostr clients connects to more than 5-10 relays to receive and transmit events.
Due to it's nature that connects to more than just a single relay, It's transmitting and retrieving the same event across relays over and over, Which then makes the client bandwidth usage to be high. And because of this, Nostr bandwidth usage is not really recommended for some users, notably mobile data users.
This project solve the problem by proxying multiple relays in a single socket while not forwarding the same event to the client.
In order to make this work properly, A nostr client should only connect to a single bostr relay.
- NodeJS (v18 or up) or Bun runtime
- A working reverse proxy like nginx or caddy
- A fast internet connection
You could set up an bostr bouncer by installing Bostr CLI, or setting up via The Source Code, or via Docker.
Tip: When dependencies installation is failed due to failed compilation of bufferutil or utf-8-validate packages, Run npm install with --omit=optional (Example: npm install --omit=optional -g bostr).
Installation Methods
Install bostr via npm:
npm install -g bostr
or via git:
npm install -g https://codeberg.org/Yonle/bostr.git
You will need to make config with the following command:
bostr makeconf bostr_config.js
Edit bostr_config.js (Could be modified) with your file editor and fill some required fields accordingly to your needs. You could run it for everyone or only for yourself.
After you finished editing the config file, You could start bostr with the following command:
bostr start bostr_config.js
Or run in background with tmux:
tmux new -d "bostr start bostr_config.js"
When configuring reverse proxy, Ensure that x-forwarded-proto header was set as https.
git clone -b stable https://codeberg.org/Yonle/bostr
cd bostr
npm install
Rename config.js.example as config.js, Start editing the file and fill some required fields accordingly to your needs. You could run it for everyone or only for yourself.
node index.js
Or run in background with tmux:
tmux new -d "node index.js"
When configuring reverse proxy, Ensure that x-forwarded-proto header was set as https.
git clone https://codeberg.org/Yonle/bostr
cd bostr
cp config.js.example config.js
You will need to edit config.js before running the bouncer.
Then, you will need to edit compose.yaml to override the forwarded port to match with the one in config.js.
docker build -t bostr:local .
docker run --rm --name bostr -p 8080:8080 -v ./config.js:/usr/src/app/config.js bostr:local
git clone -b stable https://codeberg.org/Yonle/bostr
cd bostr
bun install
Rename config.js.example as config.js, Start editing the file and fill some required fields accordingly to your needs. You could run it for everyone or only for yourself.
bun run index.js
Or run in background with tmux:
tmux new -d "bun run index.js"
When configuring reverse proxy, Ensure that x-forwarded-proto header was set as https.
You could specify the following environment variables to override the current settings:
CLUSTERS- Run Bostr with specified numbers of clusters.LOG_ABOUT_RELAYS- Whenever to log about relay connections.
