Tags are not replaced, but getting appended

[rrjanbiah]

Say, for example, if index.html is having <title> tag already, the new title tag is getting appended.. so, browser is taking the first one (which is used in the index.html).. in turn looks like the module is not working.

As a quick fix, I had to remove the <title> tag from the index.html. But, that's not the correct solution.. as I want somewhat SEO friendly without SSR for the static hosting.

Apologies for my poor English and hope the issue is clear to the author.

We can't diff what is outside of our control. SSR does a trick where it replaces by writing an attribute to server generated meta tags. We should document this. But if you add a data-sm="" attribute to any of your meta tags they will be removed when the client hydrates and replaced with what the library generates.

@ryansolid Thanks for sharing the hidden treasure :-) <title data-sm="">My title</title> worked great to avoid the appending. Feel free to close the issue unless you want to track the documentation part.

When setting title why not just remove any existing <title> tags? As there should never be more than one of those.

@andreas-ateles As I mentioned in original message, I need it for static hosting. For example, think about it when using Facebook debugger or Twitter cards. With it, it would also resolve the root/default page's title for all the pages.

It appends the head as well if you have your routes like bellow - client side.

import { Routes, Route } from "solid-app-router"
import { MetaProvider, Title } from "solid-meta";

function Home() {
  return (
    <>
      <MetaProvider>
        <Title>Home Page</Title>
      </MetaProvider>
      <div>
        <h1>Home Page</h1>
      </div >
    </>
  );
}

function About() {
  return (
    <>
      <MetaProvider>
        <Title>About Page</Title>
      </MetaProvider>
      <div>
        <h1>About Page</h1>
      </div >
    </>
  );
}

export default function App() {
  return (<>
    <h1>My Site with Lots of Pages</h1>
    <Routes>
      <Route path="/" element={<Home/>} />
      <Route path="/about"  element={< About/>}  />
    </Routes>
  <>)
}

Result:

You have multiple MetaProviders. Each acts independently. Wrap the whole application in a single MetaProvider and it should work fine.

thanks @ryansolid, it's working now... Loving solid-js so far 😀

Am I missing something? My index.html has <title data-sm="">Hardcoded Title</title>. My app only has a single <MetaProvider> at the top-level. Then, I provide a <Title> but it's still appending to the DOM according to Chrome:

<title data-sm>Hardcoded Title</title>
...
<title>Set by Title component</title>

I'm using the latest versions of solid-js and @solidjs/meta.

The reason I'm doing this is because I deploy my site as static files to GitHub Pages, which will then be indexed by search engines. For that reason I must have a <title> tag present in index.html, but I then want to overwrite it at runtime in the browser per view for better UX.

[ryansolid]

Yeah I thought this might be the case. We used to do something simple and just remove all the existing tags but now we try to upgrade but if the id doesn't match it stays I imagine. We probably need a convention here. I'm going to ask @nksaraf for his opinion as well.

[nathan-alden-sr]

See https://github.com/solidjs/solid-meta/issues/17 for what I think is an improved design that can help mitigate these issues but also provide more flexibility.

For client-side rendering, I worked around this behavior, which was undesirable for me due to the reasons stated above, by assigning an ID to the <title> element in the index.html and removing it on my index.tsx file, before calling render(). It's not a pretty solution, and there will be a tiny, unnoticeable time window during which the page won't have a title at all, but it is more SEO-friendly than the alternative.
