Cloud Native Development in Nov 2024

• What I first wanted : I want to use Telegram and WhatsApp as order notification channel

Set up the first project

• Originally, I used to use plain Lambda function. This time I will try express(https://expressjs.com/) + serverless lambda

  • serverless yaml : I uses httpApi integration

Bought E-Ink display

First of all, I tried to search the reference with despi c097 esp8266 to see the cabling between esp8266 and the driver board.

Ahhh… there is no reference.

What should I do? I visit, the product page but the page only provides technical specification and schematics. I just want to run a MicroPython code to display. (I found, after a successful result, this is not that kind of simple, like turning on the led)

Behind story

I have been using APM since 2006. the first was Jennifer (for java). and Scouter (similar to jennifer x-view)

And the year 2020, I meet elastic apm (half setup). I finished the setup from Python django monitoring, to Vue RUM(with sourcemap).

In the year 2023, I tried Sentry for the first time. It seems new and is specialized for error tracking. I have set up for NestJS(backend), React(web frontend) and ReactNative. It was not that bad with error tracking.

Tested ESP8266 with RC522 NFC/RFID Reader

RC522 is NFC/RFID reader, and it can be integrated into ESPHOME
