This blog post presents the steps required to connect to the MySql database from the command line and modify the size of a column in a table. The example is based on the MySql database that is backing Keycloak to run www.codever.land. For a setup of the environment you can see the wiki article Keycloak MySQL Setup
Key takeaways when using Open API Specification 3 to document an ExpressJS API
Recently I’ve taken the time to update the API documentation for bookmarks.dev. I used the Swagger 2.0 (aka OAS 2) before and I decided to update to OpenAPI Specification (OAS) 3. In this post I will highlight the main points about the process and documenting the API with OAS 3. Some points might still apply to the former OAS 2 (fka Swagger) documentation, but they are worth mentioning since I hadn’t payed enough attention before and I find them useful.
You can find the OAS 3 specification for bookmarks.dev on Github and the result is available at bookmarks.dev/api/docs/
Here are the key takeaways.
Example on how to call the YouTube Data API from Node.js

Improved bookmarking of StackOverflow questions
I found myself lately adding more StackOverflow questions to my dev bookmarks collection, so I took the challenge over the weekend to make this experience more pleasant. In this blog post I will present you the result - improve auto completion of bookmark attributes on creation, login with Stackoverflow account and visual hinting for stackoverflow bookmarks.
Cleaner code in an Express REST API with unified error handling
What started out as a simple code duplication removal, turned out into a major refactoring with complete rewriting of error handling, moving of business logic/db access into separate service files (about this in another blog post) and rewriting of all integration tests to use async/await. In this blog post I will focus on the custom error handling and how it made the code much cleaner for the REST API supporting www.codever.land. The API uses ExpressJS, currently in version 4.
