@jackdbd/send-telegram-message

Application that sends a message to a Telegram chat.

Development

npm run start:development -w packages/send-telegram-message

Deploy to GCP Cloud Functions

This command uploads the source code to Cloud Build, which builds the container image and deploys the application to Cloud Functions (2nd generation):

npm run deploy -w packages/send-telegram-message

Test

Run integration tests with SuperTest and Jest:

npm run test -w packages/send-telegram-message

Test the function locally

Start the function in one terminal:

npm run start:development -w packages/send-telegram-message

And call it with curl, Postman, etc:

curl -X POST \
-L "$SEND_TELEGRAM_MESSAGE_URL" \
-H "Content-Type: application/json" \
--data-raw '{
    "text": "Hello world in <b>bold</b> and <i>italic</i>"
}'

Test the function deployed on GCP Cloud Functions

If you want to test the function with curl (or Postman, etc) don't forget to include the identity token in the Authorization header, otherwise Google will return a HTTP 403.

Here is how you can make an authenticated request using the user account you are currently logged in:

curl -X POST \
-L "$SEND_TELEGRAM_MESSAGE_URL" \
-H "Authorization: Bearer $(gcloud auth print-identity-token)" \
-H "Content-Type: application/json" \
--data-raw "{
    \"text\": \"This is a message sent by <b>curl</b>\"
}"
