Reception (Mastodon API)

You can live in your existing Mastodon app as is. IceCubes, Toot!—just point them at hollo. Switch servers and the app your fingers already know stays the same: that's Reception's promise.

Reception is also the translator. When an app says "post this," it goes right on to carry out delivery to the outer universe. Reception and the Diplomacy Office share a corridor.

Highlights

• src/api/index.ts stands up hono/compress and CORS (exposing the Link header) first, then mounts v1/v2
• Validation is @hono/zod-validator plus inline zod. v2 search clamps limit to between 1 and 40
• Delivery carries an orderingKey derived from the post IRI, and excludeBaseUris prevents misdelivery to its own island
• With resolve=true, v2 search goes out to the outer universe via lookupObject(), and when it finds something, it copies it into the ledger with persistAccount/persistPost before answering

A passage from the sutra

    const activity = toCreate(post, fedCtx);
    const orderingKey = getPostOrderingKey(post.iri);
    await fedCtx.sendActivity(
      { username: handle },
      getRecipients(post),
      activity,
      {
        orderingKey,
        excludeBaseUris: [new URL(c.req.url)],
      },
    );
    if (post.visibility !== "direct") {
      await fedCtx.sendActivity({ username: handle }, "followers", activity, {
