MQTT in your browser

MQTT in your browser

MQTT is probably best known as a lightweight messaging protocol implemented for small sensors, but there is actually a JavaScript implementation called MQTT.js. It's a JavaScript implementation, so of course it works in a browser. I think it's a great option for front-end engineers who are working with MQTT/IoT-related projects (for example, creating a dashboard to visualize MQTT data). In this article, I'd like to write about what I did when I tried to connect MQTT.js to the test server (broker) of Mosquitto™.

Query to Search for an Item with Apollo

Last time was to get list of todo from Apollo. This time I am going to add task search functionality by id.

Code

Docker registry with basic auth and SSL certificate

Docker registry with basic auth and SSL certificate

Docker registry does not have authentication nor certificate mechanism so in case you have docker registry on the internet, you need something that support those in front of the registry. You can find examples using Nginx for it on the web and this is yet another one.

The architecture

Client talks to Nginx. Nginx proxies the request to the docker registry. The nginx is on the host OS - not as a container.
