I love JavaScript, but for many projects -- especially internal tools and prototypes -- setting up a full frontend JavaScript stack (npm, webpack, babel, create-react-app, redux) and all of their configuration files, folders, and scaffolding is overkill.
Hibiki HTML incrementally plugs into any backend, using any template language (even static HTML files) with a single script include. It includes a built-in frontend data model, Vue.js-like rendering, built-in AJAX integration, and a full component/library system.
It is also fully scriptable from your backend AJAX handlers. Anything that Hibiki HTML can do on the frontend can be done with a remote handler by returning specially formatted JSON actions. This allows you to write frontend logic (that would normally be JavaScript code) in your backend handlers.
Background -- Hibiki HTML is a standalone, open-source, more powerful version of the frontend language that I had built for my internal tools startup Dashborg over the past year. It is a reaction against the extreme amount of scaffolding and configuration required to set up a new frontend project, especially when you're a backend/devops/data engineer who isn't a JavaScript expert. As more Hibiki libraries are written, the advantages will hopefully become even more clear.
I'd love to get all of your feedback, questions, and comments. Would love a star on Github if you like the idea. Also, feel free to email me, and/or join the Slack workspace I set up (contact info on Github or the tutorial).
