# Interface: StringConfig

Defined in: [src/views/utils/index.ts:411](https://github.com/Dynamsoft/document-scanner-javascript/blob/main/src/views/utils/index.ts#L411)

Override the default user-facing strings displayed by the DocumentScanner. Every
field is optional; unset fields fall back to the library default. Toolbar button
labels (Re-take, Apply, Done, etc.) are not configured here — use
`correctionViewConfig.toolbarButtonsConfig` and `resultViewConfig.toolbarButtonsConfig`
for those.

Strings that include a `{count}` or `{error}` placeholder are noted inline; the
placeholder is substituted at render time.
