Cooklang-sync library (Work in progress)

Based on desings from Dropbox https://dropbox.tech/infrastructure/streaming-file-synchronization.

Suitable for syncing text files and not large (<10MB) binary files.

Roadmap

• Garbage collection for client
• Tests!
• Need to generalise, now it’s too specific to our case
• Improve DevEx for external developers
• Read only files
• Export metrics
• Security audit and hardening
• Support of symlinks
• Hidden files

Running

Start server:

cargo run

Start clients (specify directory to sync, db location, server address and JWT):

cargo run --bin client ../tmp ./db/client.sqlite3 http://localhost:8000 eyXX.XXX.XXX

Test JWT can be generated on https://jwt.io using default values and specifying your-256-bit-secret to be secret and payload in this way (exp is timestamp in seconds for token expiration and uid is user ID):

{
  "uid": 100,
  "exp": 1720260223
}
