示例1: Promise

transformFile(filename, defaultOptions, (err, result) => {
if (err) {
reject(err);
} else {
resolve(result);
}
});
});示例2: function
// Example from https://github.com/babel/babel/tree/master/packages/babel-core
const code = `class Example {}`;
const result = babel.transform(code, { /* options */ });
result.code; // Generated code
result.map; // Sourcemap
result.ast; // AST
// Examples from http://babeljs.io/docs/usage/api/
let options: babel.TransformOptions = {
plugins: [
"es2015-arrow-functions",
"es2015-block-scoped-functions",
"es2015-block-scoping",
"es2015-classes",
],
only: /.*\.js/,

};
babel.transformFile("filename.js", options, function (err, result) {
result.code;
result.map;
