HTMX is a frontend library that enables page manipulation using HTML attributes, while HMPL.js is a modern alternative that utilizes the fetch API and pure JavaScript for handling requests and responses.
Opportunities for QA engineers when transitioning to HMPL.js include increased control over testing, JavaScript skill development, and early involvement in technical decisions.
Challenges to anticipate include the lack of documentation and community support for HMPL.js, increased testing complexity as logic shifts to JavaScript, and the risk of hidden bugs in dynamic DOM structures.
A sample case study illustrates the technical changes, challenges faced, and solutions implemented when transitioning from HTMX to HMPL.js, highlighting the need for more technical and adaptive QA practices.
