chore(ts): enforce strict type checking in CI (#212) - #493
Conversation
Bitcoindefi#212) Adds noUncheckedIndexedAccess to tsconfig.json (strict was already on), a npm run typecheck script wired into the CI Type check step, and ~300 type-level fixes across lib/, app/, components/ and tests: index-access guards with ?? fallbacks where a default is meaningful, non-null assertions only where runtime invariants guarantee presence (seed data, findIndex !== -1 guards), no @ts-ignore and no new as any. Runtime behaviour unchanged; full suite 97 files / 645 tests green.

🚨 Bug: Leaderboard ranking comparison corrupted by stray logical NOTs
The rank loop was rewritten as !entries![i]!.questsCompleted < !!entries[i - 1]!.questsCompleted. The prefix ! / !! convert the numeric quest counts to booleans, so the comparison becomes false < true (i.e. 0 < 1) regardless of the actual values, and dense ranking is computed incorrectly for every leaderboard. This is a runtime behavior change, not a type-only fix. Restore the numeric comparison.
Compare the numeric quest counts instead of their boolean negations.:
if (i > 0 && entries[i]!.questsCompleted < entries[i - 1]!.questsCompleted) {

🚨 Bug: activeDistrict default becomes boolean false instead of district id
... ? params.district : !DISTRICTS![0]!.id applies a prefix logical NOT, so when no valid district param is supplied activeDistrict is false rather than the first district's id. Downstream guards (view === "district" && activeDistrict ? activeDistrict : undefined) then treat it as falsy, so the default district view no longer resolves to DISTRICTS[0].id. Drop the stray !.
Fall back to the first district id instead of a negated boolean.:
const activeDistrict = DISTRICTS.some((district) => district.id === params.district) ? params.district : DISTRICTS[0]!.id

⚠️ Bug: MDX code-fence loop re-processes the closing fence as a new block
The rewritten while exits with i pointing at the last code line (because it looks ahead at lines[i+1]), whereas the original left i on the closing ```
Skip the closing fence line so it is not reparsed as a new code block.:
while (i + 1 < lines.length && !lines[i + 1]?.startsWith("```")) {
i++
const codeLine = lines[i]
if (codeLine !== undefined) code.push(codeLine)
}
i++ // consume the closing ``` fence
nodes.push(<pre key={i} data-language={language || "text"}><code>{code.join("
")}</code></pre>)

💡 Bug: Demo prints false instead of the quote amount
console.log( Amount: ${!quote!.options[0]!.amount}) negates the amount, so the example always prints Amount: false. Although this is only a demo script, the output is clearly wrong. Remove the leading !.
Print the actual amount rather than its boolean negation.:
console.log(` Amount: ${quote!.options[0]!.amount}`)
