Semi Persistent Chat

That project is a simple semi-persistent PWA chat using web socket. Messages are kept in memory and purged after X hours on the server (configurable).

URLs sent in chat will be transformed as links. For media (image, audio or video), a preview will be displayed.

Configuration

Launch npm run config to create src/config.mjs (from src/config.mjs.dist) and update it according your needs. You should at least change "secret" (used for websocket authentification) and "origin" (your domain).

To dev

This project was bootstrapped with Create React App.

run npm run dev:client to launch client code (with watch) and npm run dev:server to launch server code

Webapp is served on port 3000 by devtools while node is launched on port 6060 (explaining while websocket and api calls are made on that port on non production env).

To deploy on production using only node

Run npm run build to generate static files into build directory, then run npm run start which will serve static files.

To deploy on production using nginx to serve static file (recommanded)

Run ./build.sh to generate static files into build directory (change PUBLIC_URL in that file if needed).

Serve static files via a web server like nginx. I’m using a symbolic link from /var/www/semi-persistent-chat to the build directory.

Launch src/server file (I suggest you to use pm2 to launch server via ./pm2.sh).

Finally, adapt nginx to let pass web socket and /api to node :

location /persistent-chat-ws/ {
        proxy_pass http://127.0.0.1:6060;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
}
location /persistent-chat/api/ {
        proxy_pass http://127.0.0.1:6060/api/;
        proxy_http_version 1.1;
}
