  • How To Get The Number Of Bytes In A String In JavaScript -

    Getting the number of bytes in a JavaScript string can be very useful.

    For example, at the time of this article being written, 01 October 2021, Twitter limits posts to 280 bytes. If you use just Latin characters, numbers, or other ASCII characters in a Twitter post, then the number of characters would be equal to the number of bytes since each ASCII character is made with 1 byte.

    But in other languages, or other non-ASCII characters like emojis, the character would likely be made with more than 1 byte.

    Essentially there are 2 steps to getting the number of bytes in a string in JavaScript.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
