In `@subtrack/src/commands.ts`:
- Around line 170-195: The `saveDb()` call in the `handleBackup` function is
ineffective until the DB path is initialized via `_dbPath`. In a fresh process,
this leaves the source database file absent, causing `copyFileSync(getDbPath(),
destPath, constants.COPYFILE_EXCL)` to fail with ENOENT. Initialize the DB path
(typically by calling the function that sets `_dbPath`) before calling
`saveDb()` to ensure the in-memory state is actually flushed to disk and the
source file exists for the backup copy operation.
- Around line 175-177: The variable declaration for `destStat` lacks an explicit
type annotation, which violates strict TypeScript settings and creates an
implicit `any` hazard. Add an explicit type annotation to the `destStat`
variable at its declaration point that matches the return type of `statSync()`.
The return type from `statSync()` in the fs module is Stats, so annotate
`destStat` with the appropriate Stats type from the fs module to satisfy strict
type checking while maintaining compatibility with the subsequent
`.isDirectory()` method call.

Initialize DB path before flushing, or first-run backup can fail.
saveDb() is a no-op until _dbPath is initialized. In a fresh process, this can leave the source DB file absent and copyFileSync(...) fails with ENOENT even for a valid destination.
Proposed fix
export async function handleBackup(destination: string) {
- // flush in-memory state to disk
- saveDb()
+ // ensure DB path exists, then flush in-memory state to disk
+ const dbPath = getDbPath()
+ saveDb()
@@
- copyFileSync(getDbPath(), destPath, constants.COPYFILE_EXCL)
+ copyFileSync(dbPath, destPath, constants.COPYFILE_EXCL)

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Add explicit type to destStat under strict TypeScript.
let destStat at line 175 has no type annotation. With strict mode enabled, this creates an implicit any hazard. The variable is assigned the return value of statSync(destination) and used with .isDirectory(), so it requires an explicit type.
Proposed fix
- let destStat
+ let destStat: ReturnType<typeof statSync>📝 Committable suggestion
