Eleventy stuff

eleventy.js

Return specific post

module.exports = function (eleventyConfig) {
  eleventyConfig.addPassthroughCopy("bundle.css");
  eleventyConfig.addPlugin(syntaxHighlight);
  eleventyConfig.addCollection("post", function (collection) {
    const coll = collection.getFilteredByTag("post");
    console.log(coll);
    return [coll[20]];
  });
};

Return first 5 posts

module.exports = function (eleventyConfig) {
  eleventyConfig.addPassthroughCopy("bundle.css");
  eleventyConfig.addPlugin(syntaxHighlight);
  eleventyConfig.addCollection("post", function (collection) {
    const coll = collection.getFilteredByTag("post");
    console.log(coll);
    return coll.slice(0, 5);
  });
};

Use functions as children

2023-10-22

Hvordan kan man lage et komponent som exposer en dataverdi som parent kan få tak i?

I.e. hvordan kan ChildComponent her gjøre dette lov?

          <ChildComponent>
            {({idFromChild}) => {
              return (
                <Button
                  href={`link/to/${idFromChild}`}
                >
					click here
                </Button>
              );
            }}
          </ChildComponent>

Slik:

export const ChildComponent = ({id}) => {
  return (
    <div>
      {children({
        id: id,
      })}
    </div>
  );
};

why not multiple BrowserRouters

Drew Reese - . There becomes an issue when you start nesting routers within routers, or rather it's the routing contexts within other routing contexts. The contexts of "outer" routers are unaware of what nested "inner" routers have handled.

https://stackoverflow.com/questions/67175039/is-it-possible-to-have-multiple-browserrouter-in-react-app

scriptedalchemy - Dont think you want have multiple browser routers. Youd want to use switch or something else. Only hosts should implement browser router, and only once. Usually I have a standalone wrapper that has like a mini shell for each app. Then I federate the inner component. So browser router stays on the shell layer

nebarf - Single source of truth: having a single "component" updating the browser history brings a lot of flexibility (e.g. it could really help in case you're gradually migrating a legacy system following the strangler pattern).
