tiennm99 3fd137a233 refactor(web): rebuild the frontend on SvelteKit, TypeScript and Tailwind
The app was a single-entry React SPA: one index.html that the assembler
copied to every dataset path, with a hand-rolled router resolving the
dataset from window.location and the title patched in at runtime because
one file had to serve every route.

SvelteKit prerenders a real page per route instead. The entry generator
in routes/[dataset]/+page.ts reads the same datasets.json the assembler
does, so the set of pages and the set of databases cannot drift apart,
and each dataset page ships its own <title> and description.

Everything framework-free moved across unchanged in behaviour and became
typed: the admission blocks, subject list, query classifier and SQL
presets. `Student` now mirrors the 22-column table, so a mistyped column
name fails the build rather than rendering blank.

Tailwind replaces the stylesheet. Theme tokens are CSS variables, which
keeps dark mode a single block of overrides rather than a `dark:` variant
on every class. The score tiers stay hand-written CSS: the class is
chosen at runtime from a score, and no utility generator can see that.

Adds the tests the frontend never had, over the three modules where a
silent wrong answer is possible — most importantly that toAscii here
folds exactly as ToAscii does in the parser, which is what makes
accent-insensitive search find anything.

The assembler stops copying index.html per dataset and checks that the
build prerendered each one instead. The database presence, raw-artifact
and idempotence guards are untouched.

Verified: 25 tests, ESLint and svelte-check clean, and a full
`assemble site` producing /thptqg/, /thptqg/2016/, /thptqg/2017/ and
404.html with absolute asset URLs. Not verified in a browser — this
machine has none.

thptqg

Tra cứu điểm thi THPT Quốc gia — exam-score lookup for Vietnam's national high school graduation exam. Client-side SQL (sql.js) over a SQLite database built from the published .xls/.xlsx score files by the Go parser module. Where those files come from: data pipeline.

Dataset Exam Candidates Site

2017 2017 861,068 /2017/

Two earlier 2017 publications (2017-old, 2017-old2) were kept for a while because they disagreed with the current one. They have been removed; they remain in git history.

Layout

The repository is one directory per pipeline stage, plus the two stores they pass between them.

crawler/      Go   — re-fetches the source spreadsheets      → data/
parser/       Go   — Excel to SQLite                          data/ → .db
assembler/    Go   — verifies, compresses, builds, assembles  .db + web/ → _site/
web/          npm  — the frontend, one SvelteKit app for every dataset
data/<id>/         raw Excel files, one directory per dataset
datasets.json      the registry: which datasets exist, and their expected size
docs/              architecture, data pipeline, deployment

Each stage runs on its own and hands its output to the next through the stores. web/ is the only npm project; the three stages are independent Go modules.

datasets.json is the contract between them. It is JSON because Go and the web app both read it and neither needs a dependency to do so; presentation stays in web/src/lib/datasets.ts, keyed by id, which fails loudly if the two disagree.

The dataset id is one identifier end to end:

data/2017/ → parser/configs/2017.yml → db/2017.db.gz → /thptqg/2017/

Build

(cd web && npm ci)
go -C assembler run ./cmd/assemble        # databases, then the site, into _site/
npx serve _site

That one command compiles the parser, builds and verifies each database against its registry row count, compresses it, builds the web app and assembles _site — refusing to continue if a database is short, an artifact looks truncated, or one is missing altogether. Sub-steps when iterating:

go -C assembler run ./cmd/assemble db 2017   # one database
go -C assembler run ./cmd/assemble site      # web build and _site only
go -C assembler run ./cmd/assemble verify A B  # compare two sets of databases
(cd web && npm run dev)                      # the app against staged databases

The source spreadsheets are committed, so a crawl is only needed to refresh them:

go -C crawler run ./cmd/crawl 2016
go -C crawler run ./cmd/crawl 2017

Each reads the download links out of the article that published the dataset, so no link list is kept in the repository. Crawling is idempotent — files already present are skipped — and is never part of the build.

Pushing to main runs the same steps in .github/workflows/deploy-pages.yml and publishes to GitHub Pages.

Adding a dataset

  1. Put the Excel files in data/<id>/
  2. Add parser/configs/<id>.yml — sheet mode, column indices, validation guards. No SQL; the schema is canonical.
  3. Add an entry to datasets.json with its expected row count and size
  4. Add the matching presentation to CONTENT in web/src/lib/datasets.ts

Everything else follows: the assembler, the router and the hub all read the registry, and the UI adapts to whichever columns the dataset fills. Steps 3 and 4 check each other, so forgetting either one fails rather than half-working.
