示例1:
const options: babel.TransformOptions = {
ast: true,
sourceMaps: true
};
babel.transform("code();", options, (err, result) => {
const { code, map, ast } = result!;
});
const transformSyncResult = babel.transformSync("code();", options);
if (transformSyncResult) {
const { code, map, ast } = transformSyncResult;
}
babel.transformFile("filename.js", options, (err, result) => {
const { code, map, ast } = result!;
});
babel.transformFileSync("filename.js", options)!.code;
const sourceCode = "if (true) return;";
const parsedAst = babel.parse(sourceCode, options);
babel.transformFromAst(parsedAst!, sourceCode, options, (err, result) => {
const { code, map, ast } = result!;
});
const transformFromAstSyncResult = babel.transformFromAstSync(parsedAst!, sourceCode, options);
const { code, map, ast } = transformFromAstSyncResult!;
