# Oxc Transform
This is alpha software and may yield incorrect results, feel free to [submit a bug report](https://github.com/oxc-project/oxc/issues/new?assignees=&labels=C-bug&projects=&template=bug_report.md).
## TypeScript and React JSX Transform
```javascript
import assert from 'assert';
import oxc from 'oxc-transform';
const { code, declaration, errors } = oxc.transform(
'test.ts',
'class A<T> {}',
{
typescript: {
declaration: true, // With isolated declarations in a single step.
},
},
);
assert.equal(code, 'class A {}\n');
assert.equal(declaration, 'declare class A<T> {}\n');
assert(errors.length == 0);
```
## [Isolated Declarations for Standalone DTS Emit](https://devblogs.microsoft.com/typescript/announcing-typescript-5-5/#isolated-declarations)
Conforms to TypeScript compiler's `--isolatedDeclarations` `.d.ts` emit.
### Usage
```javascript
import assert from 'assert';
import oxc from 'oxc-transform';
const { map, code, errors } = oxc.isolatedDeclaration('test.ts', 'class A {}');
assert.equal(code, 'declare class A {}\n');
assert(errors.length == 0);
```
### API
See `index.d.ts`.
```typescript
export declare function transform(
filename: string,
sourceText: string,
options?: TransformOptions,
): TransformResult;
export function isolatedDeclaration(
filename: string,
sourceText: string,
options?: IsolatedDeclarationsOptions,
): IsolatedDeclarationsResult;
```
### Supports WASM
