  • Imba – The friendly full-stack language
    I remember Opa http://opalang.org/ tried something similar at the time when MongoDB was new and modern. - Source: Hacker News / 7 months ago
  • Ask HN: What web frameworks/technologies did not succeed as per your expectation
    We come across some web frameworks and technologies that we think will succeed, but they wither away as time passes by and don't succeed to the level we expected. Which web frameworks and or technologies did you come across that you thought would succeed but did not as per your expectations? For example, I thought that Opa Lang[0] and UrWeb[1] would succeed but did not, even though the ideas were sound. [0]... - Source: Hacker News / 9 months ago
  • Modern JavaScript:Everything you missed over the last 10 years(ECMAScript 2020)
    I think the Opa language was doing JSX-like code in the frontend before JSX http://opalang.org/ Both Opa and JSX were created in 2011. Opa had other innovations as well, such having the same code base run on both client and server (like Next.js). Unfortunately it didn't get traction and was abandoned by the creators. - Source: Hacker News / almost 3 years ago

  • Is there a technology for reusing HTML components?
    Sounds like what you want is a static site generator. I've used Harp for a long time but I'm not sure it's really maintained these days, so you might also look at 11ty. Source: over 1 year ago
