Migrating Azure Functions from JSDoc JavaScript to TypeScript
All of these affordances are available to me with TypeScript, and I want to keep them. Let's begin migrating. Incidentally, the code for this migration lies in this PR.

Migrating from ts-node to Bun
These scripts are implemented as a simple ts-node console app. For historical reasons it's called trim-xml (it originally just truncated the sitemap.xml file). It's not a particularly good name but I'm not going to change it now. As the blog is open source, you can see the [code of trim-xml here](https://github.com/johnnyreilly/blog.johnnyreilly.com/tree/main/trim-xml].

Docusaurus blogs: adding breadcrumb Structured Data
I'm somewhat on the fence as to whether it's useful to have a breadcrumb for each tag. In fact, originally I didn't have it when I first added support. But I've added it in as it's not a lot of work and it's not a lot of code. I'm not sure if it's useful or not. I've added it now; I'm going to leave it in in place for a bit and see how it goes.

Serving Docusaurus images with Cloudinary
You will also need to disable the url-loader in your Docusaurus build which transforms images into base64 strings, as this will conflict with the plugin. There isn't a first class way to do this in Docusaurus at present. However by setting the environment variable WEBPACK_URL_LOADER_LIMIT to 0 you can disable it. You can see an implementation example in this pull request. It amounts to adding the cross-env package and then adding the following to your package.json:
//@ts-check const visit = require('unist-util-visit'); /** * Create a remark plugin that will replace image URLs with Cloudinary URLs * @param {*} options cloudName your Cloudinary’s cloud name eg demo, baseUrl the base URL of your website eg https://blog.johnnyreilly.com - should not include a trailing slash, will likely be the same as the config.url in your docusaurus.config.js * @returns remark plugin that will replace image URLs with Cloudinary URLs */ function imageCloudinaryRemarkPluginFactory( /** @type {{ cloudName: string; baseUrl: string }} */ options ) { const { cloudName, baseUrl } = options; const srcRegex = / src={(.*)}/; /** @type {import('unified').Plugin<[], import('hast').Root>} */ return function imageCloudinaryRemarkPlugin() { return (tree) => { visit(tree, ['element', 'jsx'], (node) => { if (node.type === 'element' && node['tagName'] === 'img') { // handles nodes like this: // { // type: 'element', // tagName: 'img', // properties: { // src: 'https://some.website.com/cat.gif', // alt: null // }, // ... // } const url = node['properties'].src; node[ 'properties' ].src = `https://res.cloudinary.com/${cloudName}/image/fetch/${url}`; } else if (node.type === 'jsx' && node['value']?.includes('')) { // handles nodes like this: // { // type: 'jsx', // value: '' // } const match = node['value'].match(srcRegex); if (match) { const urlOrRequire = match[1]; node['value'] = node['value'].replace( srcRegex, ` src={${`\`https://res.cloudinary.com/${cloudName}/image/fetch/${baseUrl}\$\{${urlOrRequire}\}\``}}` ); } } }); }; }; } module.exports = imageCloudinaryRemarkPluginFactory;

How I Ruined My SEO
yeah I'm hoping that my redirect story is now quite good - see dynamic redirect code here:
https://github.com/johnnyreilly/blog.johnnyreilly.com/blob/m...
as to the duplicate content, Docusaurus generates /tags/ and /pages/ content by default that I strip from from my sitemap manually.

How I ruined my SEO
I started using fontaine on my blog. If you haven't tried it out, you can find it here. It helps reduce Cumulative Layout Shift. The flash of unstyled content jank that you can see when you first land on a site, before fonts have loaded. I can't see why that would be an issue. It should improve my blogs Core Web Vitals and help stuff rank better, not worse. I think this is a red herring.

Direct Postgres connection to Supabase from Vercel Edge in Next.js
Is anyone aware of a way to make a direct connection to Postgres with transaction support on Vercel Edge functions? The 'pg' package doesn't work on edge for me. The obvious answer would be @vercel/postgres but I find their lack of documentation rough and for whatever reason I can't get it to connect on my local computer using the Supabase-provided local database connection string. This is apparently a known issue (https://github.com/vercel/storage/issues/123, https://github.com/vercel/examples/issues/701) where in order to make this (or neon's package) work you need a WebSocket proxy? Is a direct Postgres connection from edge just impossible right now? Or do others have it working somehow?
