6 # Mrjunejune Personal Site
7
8 Use this skill for `mrjunejune/`, the personal website served by a C backend.
9
10 ## Structure
11
12 - `mrjunejune/main.c`: C web server, routes, APIs, S3 upload URL generation, editor persistence, media conversion, WebSocket chat.
13 - `mrjunejune/src/`: static site source files and HTML templates.
14 - `mrjunejune/src/parts/`: shared HTML includes used by `{{...}}` template placeholders.
15 - `mrjunejune/src/public/`: public assets, PWA files, media, generated JS, icons, resume PDF.
16 - `mrjunejune/test/`: integration tests and snapshots.
17 - `mrjunejune/BUILD`: Bazel build, bundle, asset movement, and test-visible filegroups.
18 - `mrjunejune/.config` and `.config.development`: server configuration. Do not commit secrets.

20 ## How rendering works
21
22 Handlers allocate a response body from `Dowa_Arena`, render an HTML file with `Seobeo_Render_Html_FilePath`, and return a response map:
23
24 ```c
25 Seobeo_Request_Entry *resp = NULL;
26 char *final_body = Dowa_Arena_Allocate(arena, 50 * 1024);
27 Seobeo_Render_Html_FilePath(final_body, "/tools/index.html", arena);
28 Dowa_HashMap_Push_Arena(resp, "body", final_body, arena);
29 return resp;
30 ```
31
32 The simple template renderer replaces `{{...}}` tokens with file contents loaded through `Seobeo_Web_LoadFile`.
33
34 ## Routes and features
35
36 Existing route areas include:
37
38 - Home, resume, tools, markdown-to-HTML, file converter, blog, talk/chat, notes, and editor pages.
39 - Redirect helpers built with `CREATE_REDIRECT_HANDLER`.
40 - File/media conversion APIs using `ffmpeg` and temporary files under `/tmp`.
41 - S3 presigned upload URL API using `Authorization: Bearer <token>`.
42 - Editor save/load APIs backed by `deita` SQLite.
43 - WebSocket chat broadcasting through seobeo WebSocket server APIs.
44
45 When adding pages, add the HTML/CSS/JS under `src/`, register a route in `main.c`, and update tests/snapshots if the route should be covered.
46
47 ## Build and test
48
49 ```bash
50 bazel build //mrjunejune:mrjunejune_server
51 bazel build //mrjunejune:mrjunejune_server_bundle
52 bazel test //mrjunejune/test:integration_test
53 ```
54
55 Use the debug server when investigating routing or networking:
56
57 ```bash
58 bazel build //mrjunejune:mrjunejune_server_debug -c dbg
59 ```

61 ## Production-minded checklist
62
63 - Use Dowa's fixed-width aliases and `boolean`/`TRUE`/`FALSE` in first-party C
64 instead of introducing `<stdint.h>` `_t` types or `<stdbool.h>` `bool`.
65 - Keep auth-protected APIs strict: missing auth should be `401`, invalid token `403`, malformed JSON/input `400`, unavailable DB/S3/ffmpeg `500`.
66 - Never hardcode secrets. Read configuration from `.config` or environment wiring already used by the Bazel target.
67 - For uploads and downloads, validate filenames and content lengths before touching `/tmp`.
68 - For binary responses, set `content-length` and avoid string-only operations on body bytes.
69 - If a route is part of the public website, add or update snapshot coverage in `mrjunejune/test`.
70 - Keep PWA changes consistent across `manifest.json`, `sw.js`, icons, and `PWA_SETUP.md`.
71 - Reuse `seobeo`, `dowa`, `deita`, `s3`, and `markdown_converter` instead of adding parallel implementations.
