## Summary 1. **Extract pure logic** out of the 1056-line `SQLEditor.tsx` monolith into unit-tested functions in `SQLEditor.utils.ts`. 2. **Remove `rawSql()` from the SQL editor** and tighten the untrusted→safe boundary per the `safe-sql-execution` model. ## Extracted functions (+ tests) - `getEditorSql(editor, snippetContent?)` — selection → full value → snippet fallback. Returns an **`UntrustedSqlFragment`** so editor/snippet SQL keeps its provenance. - `computeErrorHighlightLine(error, startLineNumber)` — parses the `LINE n:` marker + selection offset. - `assembleCompletionDiff(meta, text)` — before/selection/after assembly for the AI completion diff. - `buildExplainSql(sql, impersonatedRoleState)` — takes an already-safe fragment; EXPLAIN ANALYZE + role impersonation + rollback wrapping. - `buildDebugPromptText(sql, errorMessage)` — the assistant debug prompt string. ## Safe-SQL boundary - `rawSql()` is no longer used anywhere in the SQL editor. - `executeQuery` / `executeExplainQuery` now **require a `SafeSqlFragment`** — safe by construction, so they can never auto-run untrusted SQL. - `acceptUntrustedSql` promotion happens **only in the small run/explain gesture handlers** (`executeQueryFromButton`, `handleRunShortcut`, `handleRunExplain`, and the warning-modal confirm handlers), never buried in the long helpers. ## Verification - `vitest` — 156 pass (11 characterization + 145 utils, incl. new cases) - `pnpm --filter studio typecheck` — clean for all SQL editor files (two unrelated `@sentry/tanstackstart-react` module-resolution errors exist on current master pre-install; not touched by this PR) - `eslint` — 0 errors <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Enhancements** * Improved SQL execution and EXPLAIN workflows with safer handling at run and analysis actions. * Enhanced SQL selection and snippet handling in the editor. * Improved error highlighting to more accurately identify affected lines. * Refined completion previews and debugging prompts for clearer results. * EXPLAIN ANALYZE now supports rollback-wrapped execution and avoids duplicate wrapping. * **Bug Fixes** * Improved behavior when working with selected, empty, or missing SQL content. * Prevented existing EXPLAIN statements from being unnecessarily modified. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Writing components
Where to create your components
- For components that declare the general structure and layout of a page:
/components/layouts/xxx
- For components that are tightly coupled to a specific interface:
/components/interfaces/xxx
- For components that are meant to be reusable across multiple pages:
/components/ui/xxx
- Note: We're gradually moving files out of the
to-be-cleanedfolder into the respective folders as we refactor
Component structure
- If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an
index.tsxas an entry point - Otherwise it can just be a file on its own
- For example:
-
components/ui - SampleComponentA - SampleComponentA.tsx - SampleComponentA.constants.ts - SampleComponentA.utils.ts - SampleComponentA.types.ts - index.ts - SampleComponentB.tsx
-
Template for building components
// Declare the prop types of your component
interface ComponentAProps {
sampleProp: string
}
// Name your component accordingly
const ComponentA = ({ sampleProp }: ComponentAProps) => {
return <div>ComponentA: {sampleProp}</div>
}
export default ComponentA
