#### Experimental TSRX

Files ending in `.tsrx` are recognized automatically as TypeScript TSRX; they
do not need to be listed in `options.extensions`. Both the native and Babel
compiler backends preserve the `.tsrx` filename when invoking their TSRX
frontends.

Scoped CSS emitted by either backend is exposed as a sibling virtual CSS
sidecar and imported once from the compiled module. The sidecar goes through
Vite's normal CSS pipeline, so extraction and injection work in development,
production builds, and SSR, including client HMR and SSR development style
collection. A file that emits no CSS has no sidecar import.

The Babel backend chains TSRX source maps through the later lazy-module and
refresh transforms. The native compiler does not currently emit the required
TSRX projection map, so native `.tsrx` transforms return no source map. With
`compiler: "native"` and custom `babel` options, the custom Babel support pass
runs after native TSRX lowering (on ordinary JavaScript); ordinary JSX/TSX
keeps the existing pre-native ordering.

With `serverFunctions` enabled, function-level `"use server"` directives work
in `.tsrx` with both compiler backends. The plugin lowers TSRX first, then runs
the same native directive transform while retaining the authored `.tsrx` path
for stable client/server function IDs. TSRX's host-defined
`module server { ... }` profile is not supported.

#### options.babel

- Type: Babel.TransformOptions
- Default: {}

Pass any additional [babel transform options](https://babeljs.io/docs/en/options). Those will be merged with the transformations required by Solid.
With the native compiler these options normally run before JSX lowering; for
`.tsrx` only, they run after native TSRX lowering as described above.

Vite's normal CSS pipeline, so extraction and injection work in development,
production builds, and SSR, including client HMR and SSR development style

#### Experimental TSRX

Files ending in `.tsrx` are recognized automatically as TypeScript TSRX; they
do not need to be listed in `options.extensions`. Both the native and Babel
compiler backends preserve the `.tsrx` filename when invoking their TSRX
frontends.

Scoped CSS emitted by either backend is exposed as a sibling virtual CSS
sidecar and imported once from the compiled module. The sidecar goes through
Vite's normal CSS pipeline, so extraction and injection work in development,
production builds, and SSR, including client HMR and SSR development style
collection. A file that emits no CSS has no sidecar import.

The Babel backend chains TSRX source maps through the later lazy-module and
refresh transforms. The native compiler does not currently emit the required
TSRX projection map, so native `.tsrx` transforms return no source map. With
`compiler: "native"` and custom `babel` options, the custom Babel support pass
runs after native TSRX lowering (on ordinary JavaScript); ordinary JSX/TSX
keeps the existing pre-native ordering.

With `serverFunctions` enabled, function-level `"use server"` directives work
in `.tsrx` with both compiler backends. The plugin lowers TSRX first, then runs
the same native directive transform while retaining the authored `.tsrx` path
for stable client/server function IDs. TSRX's host-defined
`module server { ... }` profile is not supported.

#### options.babel

- Type: Babel.TransformOptions
- Default: {}

Pass any additional [babel transform options](https://babeljs.io/docs/en/options). Those will be merged with the transformations required by Solid.
With the native compiler these options normally run before JSX lowering; for
`.tsrx` only, they run after native TSRX lowering as described above.

#### Experimental TSRX

Files ending in `.tsrx` are recognized automatically as TypeScript TSRX; they
do not need to be listed in `options.extensions`. Both the native and Babel
compiler backends preserve the `.tsrx` filename when invoking their TSRX
frontends.

Scoped CSS emitted by either backend is exposed as a sibling virtual CSS
sidecar and imported once from the compiled module. The sidecar goes through
Vite's normal CSS pipeline, so extraction and injection work in development,
production builds, and SSR, including client HMR and SSR development style
collection. A file that emits no CSS has no sidecar import.

The Babel backend chains TSRX source maps through the later lazy-module and
refresh transforms. The native compiler does not currently emit the required
TSRX projection map, so native `.tsrx` transforms return no source map. With
`compiler: "native"` and custom `babel` options, the custom Babel support pass
runs after native TSRX lowering (on ordinary JavaScript); ordinary JSX/TSX
keeps the existing pre-native ordering.

With `serverFunctions` enabled, function-level `"use server"` directives work
in `.tsrx` with both compiler backends. The plugin lowers TSRX first, then runs
the same native directive transform while retaining the authored `.tsrx` path
for stable client/server function IDs. TSRX's host-defined
`module server { ... }` profile is not supported.

#### options.babel

- Type: Babel.TransformOptions
- Default: {}

Pass any additional [babel transform options](https://babeljs.io/docs/en/options). Those will be merged with the transformations required by Solid.
With the native compiler these options normally run before JSX lowering; for
`.tsrx` only, they run after native TSRX lowering as described above.

refresh transforms. The native compiler does not currently emit the required
TSRX projection map, so native `.tsrx` transforms return no source map. With
`compiler: "native"` and custom `babel` options, the custom Babel support pass
runs after native TSRX lowering (on ordinary JavaScript); ordinary JSX/TSX
keeps the existing pre-native ordering.

With `serverFunctions` enabled, function-level `"use server"` directives work
in `.tsrx` with both compiler backends. The plugin lowers TSRX first, then runs
the same native directive transform while retaining the authored `.tsrx` path
for stable client/server function IDs. TSRX's host-defined
`module server { ... }` profile is not supported.

#### options.babel

- Type: Babel.TransformOptions
- Default: {}

Pass any additional [babel transform options](https://babeljs.io/docs/en/options). Those will be merged with the transformations required by Solid.
With the native compiler these options normally run before JSX lowering; for
`.tsrx` only, they run after native TSRX lowering as described above.

An array of custom extension that will be passed through the solid compiler.
By default, the plugin only transform `jsx` and `tsx` files.
By default, the plugin transforms `jsx`, `tsx`, and experimental `tsrx` files.
TSRX is always recognized and does not need to be added here.
This is useful if you want to transform `mdx` files for example.
