Your NameandClaude Sonnet 5 59d1033a92 feat(web): image and file message attachments (send + render)
- lib/api/upload.ts: POST /v0/file/u/ (docs/IM-前后端对接文档.md:460-461) --
  a separate surface from /v1/im/*, at the tenant's file base URL, auth'd
  with X-MeetingIM-Auth: token <token> rather than Authorization: Bearer
  (matches upstream Tinode's own LargeFileHelper convention).
- lib/tinode/attachments.ts: sendImage/sendFile. Files <= the inband limit
  go in directly as base64 (Drafty.insertImage's `bits` field / attachFile's
  `data` field) with no upload round trip; larger ones upload first and
  reference the returned URL. Simplified from the old app's urlPromise
  dance (optimistic local preview while the upload runs in the background)
  by just awaiting the upload before creating the message -- less
  optimistic, meaningfully simpler.
- AttachmentPreview.tsx: image/file bubble rendering. Externally-referenced
  (non-inline) attachments need an authenticated fetch into a blob URL,
  not a plain <img src>/<a href> -- GET /v0/file/s/{file_id} requires the
  same custom auth header uploads do, which a bare element can't attach.
- drafty.tsx: wired the 'IM'/'EX' Drafty style-tag cases to these.

Verified end to end: sent a real inline image (confirmed the exact IM
entity shape in the outgoing WS packet, and that the <img> decoded and
loaded from its own base64 data) and a real inline file (rendered with the
correct icon/size/download affordance).

Known gap: voice messages (MediaRecorder + AU entities) not built yet --
meaningfully more complex (hold-to-record gesture, audio encoding,
duration/waveform) and deliberately left for a following pass rather than
rushed.

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some Oxlint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the Oxlint configuration

If you are developing a production application, we recommend enabling type-aware lint rules by installing oxlint-tsgolint and editing .oxlintrc.json:

{
  "$schema": "./node_modules/oxlint/configuration_schema.json",
  "plugins": ["react", "typescript", "oxc"],
  "options": {
    "typeAware": true
  },
  "rules": {
    "react/rules-of-hooks": "error",
    "react/only-export-components": ["warn", { "allowConstantExport": true }]
  }
}

See the Oxlint rules documentation for the full list of rules and categories.
