huge thank you to whichever @nodejs.org contributors are writing the type-level support for new api's like the `parseArgs` one. it's really cool to see smarter types get built into the standard libraries.
screenshot of parseArgs usage where the type of an argument, called execute, is correctly inferred as a boolean. the code: const { values, positionals } = parseArgs({ allowPositionals: true, options: { execute: { type: "boolean", default: false }, }, }); and the inference const values: { execute: boolean; }

Hi! This is a @bsky.app app for viewing the overlap between the followers and following lists for you and your friends :)

bsky-follows.info
bluesky follows dashboard for @tylur.dev and @francoisbest.com - it shows a list of mutual mutuals on the left with their name, handle, and avatars. On the right is a 4 circle venn diagram (two per each user, followers & following) that is interactive for selecting a relationship. For example, you could click Tyler's followers + Francois Best's Followers to see which of those are in common.

this is a fun use case for a template literal tag function
adding a html function to the example from axel's post - the code: function escapeHtml(str) { return str .replace(/&/g, '&amp;') // first! .replace(/>/g, '&gt;') .replace(/</g, '&lt;') .replace(/"/g, '&quot;') .replace(/'/g, '&#39;') .replace(/`/g, '&#96;'); } function html(strings, ...values) { return strings.reduce((result, str, i) => { const value = values[i]; const escaped = value != null ? escapeHtml(String(value)) : ''; return result + str + escaped; }, ''); } const tmpl = (addrs) => html` <table> ${addrs.map( (addr) => html` <tr> <td>${addr.first}</td> <td>${addr.last}</td> </tr> `.trim() ).join('')} </table> `.trim();

kagi.com/assistant is a great example of this. The default experience is to hardly respond with any text at all and it always links things.
ai response to "who is dan abramov?" - "Dan Abramov is a renowned figure in web development, best known as the co-creator of Redux and a core contributor to React. He played a pivotal role in shaping modern frontend development practices. Previously, he worked at Meta (formerly Facebook), where he contributed significantly to the React ecosystem before departing in 2023"

just released 0.3.0 of prototypey.org with support for inference and validation from json definitions. docs in the readme:
github.com/tylersayshi/...
code example showing fromJSON called on full lexicon json definition - full code: const lexicon = fromJSON({ id: "app.bsky.actor.profile", defs: { main: { type: "record", key: "self", record: { type: "object", properties: { displayName: { type: "string", maxLength: 64, maxGraphemes: 64, }, description: { type: "string", maxLength: 256, maxGraphemes: 256, }, }, }, }, }, }); type Profile = Infer<typeof lexicon>; const george: Profile = { $type: "app.bsky.actor.profile", description: "George", }; lexicon.validate({ foo: "bar" }); // will fail lexicon.validate(george); // will pass 🎉

v0.1.0 of prototypey.org is live!

there are definitely bugs for now, but I'm super happy about how this has come together so far.

please try writing an @atprotocol.dev lexicon in typescript!

inferring simple types for application use from full atproto lexicon json schemas
code snippet showing a normal json lexicon definition, followed by a use of a generic called InferNS - for infer namespace. and then a usage of the "main" type to create a thing named blob... here's the code const schema = { "lexicon": 1, "id": "app.bsky.actor.profile", "defs": { "main": { "type": "record", "key": "self", "record": { "type": "object", "properties": { "displayName": { "type": "string", "maxLength": 64, "maxGraphemes": 64, }, "description": { "type": "string", "maxLength": 256, "maxGraphemes": 256, }, }, }, }, }, } as const; type Schema = InferNS<typeof schema>; const main: Schema["main"] = { displayName: "Blob", description: "I am a blob dude", }; console.log(`hi ${main.displayName}`); hover state of the inferred Schema - it reads type Schema = { main: { displayName?: string; description?: string; }; }

working through a thought for how to write lexicons in typescript
profile namespace lexicon for the app.bsky.actor.profile in an experimental api that mixes functions for primitives with type-hinting objects const profileNamespace = lx.namespace({ id: "app.bsky.actor.profile", defs: { main: lx.record({ key: "self", record: lx.object({ displayName: lx.string({ maxLength: 64, maxGraphemes: 64 }), description: lx.string({ maxLength: 256, maxGraphemes: 256 }), }), }), }, });

atproto people: is this good?
prototype of typescript validator style lexicon library api const arkProfile = ns({ id: "app.bsky.actor.profile", models: { main: { displayName: { type: "string?", maxLength: 64, graphemes: 64 }, description: { type: "string?", maxLength: 64, graphemes: 64 } } } }) const zodProfile = ns({ id: "app.bsky.actor.profile", models: { main: { displayName: { type: z.string().optional(), maxLength: 64, graphemes: 64 }, description: { type: z.string().optional(), maxLength: 64, graphemes: 64 } } } })
