# Deprecation: #102440 - EXT:t3editor merged into EXT:backend {#deprecation-102440-1700638677}

See [forge#102440](https://forge.typo3.org/issues/102440)

## Description {#description}

The JavaScript module specifier for modules shipped with the previous "t3editor"
extension has changed from `@typo3/t3editor/` to
`@typo3/backend/code-editor/`. The old specifier `@typo3/t3editor/` is
still available, but deprecated.

The value of the existing TCA option `renderType` switched from `t3editor` to
`codeEditor`.

## Impact {#impact}

The module specifier `@typo3/t3editor/` automatically maps to
`@typo3/backend/code-editor/`. The TCA render type `t3editor` is
automatically migrated to `codeEditor`, triggering a deprecation log entry.

## Affected installations {#affected-installations}

All extensions using t3editor are affected.

## Migration {#migration}

The JavaScript module namespace `@typo3/t3editor/` maps to
`@typo3/backend/code-editor/`.

Rewrite all TCA render types usages of `t3editor` to `codeEditor`.
