Telegram crypto group assistant

Telegram bot which enhance your group research about a coin with AI.

Development

Create a local mongo database

# Warning: we assume that the host is secured enough to expose the container on the port 27017
docker run -it -d --name wagmi-mongo -p 27017:27017 --restart=unless-stopped -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=pwd mongo

docker exec -it wagmi-mongo mongosh -u root -p pwd --authenticationDatabase admin

Once in the mongo shell, create the wagmi user which will be in charge of the wagmi database. For security reason, root user is just used via mongoshell for maintenance.

use wagmi

db.createUser({
    user: "wagmi",
    pwd: "password",
    roles: [ "readWrite", "dbAdmin" ]
})

Start dev environnement

$npm i
$npm run dev
$npm run start

• set "Custom TCP"
• set port to 27017
• set from my IP (preferably set a VPN IP)
