Add optional post-level and localized title fields, and use a new postTitleText helper for Resource.title so card/list surfaces prefer short backend-provided titles instead of full body text. When title is missing, fallback to the first non-empty body line, then filename, then post id. Document the backend handoff in docs/posts-title-api.md alongside the other backend task docs.

# Posts title fields for list/card surfaces
|
||
|
||
Front-end list/card surfaces such as **热门资料**, **官方推荐**, and **全部资料** should display a short title, not the full Telegram/body text.
|
||
|
||
## Affected endpoints
|
||
|
||
Any endpoint returning `Post` items should include a short title when available:
|
||
|
||
- `GET /api/posts`
|
||
- `GET /api/posts/search`
|
||
- `GET /api/posts/recommended`
|
||
- `GET /api/posts/:id`
|
||
|
||
## Recommended response shape
|
||
|
||
```jsonc
|
||
{
|
||
"id": "string",
|
||
"title": "ARK 2026 共识加速计划", // optional global fallback title
|
||
"text": "完整正文 / Telegram-style body text...",
|
||
"localizations": {
|
||
"zh": {
|
||
"title": "ARK 2026 共识加速计划",
|
||
"text": "完整中文正文...",
|
||
},
|
||
"en": {
|
||
"title": "ARK 2026 Consensus Acceleration Plan",
|
||
"text": "Full English body...",
|
||
},
|
||
},
|
||
}
|
||
```
|
||
|
||
## Front-end fallback order
|
||
|
||
For `Resource.title`, front-end reads:
|
||
|
||
1. `localizations[currentLang].title`
|
||
2. `post.title`
|
||
3. first non-empty line of localized/full `text`
|
||
4. first attachment filename
|
||
5. `post.id`
|
||
|
||
So backend can roll this out gradually: old posts without `title` still render, but long body text will be reduced to its first line.
|
||
|
||
## Requirement
|
||
|
||
Do **not** put an entire body paragraph into `title`. `title` should be concise enough for a two-line card/list title.
|
||
|
||
Examples:
|
||
|
||
| Good title | Bad title |
