示例1: _rewriteImportStatements
/**
* Rewrite import declarations source URLs reference the bundle URL for
* bundled files and import names to correspond to names as exported by
* bundles.
*/
private _rewriteImportStatements(baseUrl: ResolvedUrl, node: babel.Node) {
const this_ = this;
traverse(node, {
noScope: true,
// Dynamic import() syntax doesn't have full type support yet, so we
// have to use generic `enter` and walk all nodes until that's fixed.
// TODO(usergenic): Switch this to the `Import: { enter }` style
// after dynamic imports fully supported.
enter(path: NodePath) {
if (path.node.type === 'Import') {

// we'll skip them.

// excluded or something) so we should just ensure the URL is
// converted back to a relative URL.

}示例2: Set
return importSpecifiers.reduce((prev, curr: t.ImportSpecifier) => {
if (t.isImportSpecifier(curr)) {
prev.add(curr.imported.name)
}
return prev
}, new Set())示例3:
const specifier = specifiers.find(item => {
return t.isImportSpecifier(item) && item.imported.name === providerComponentName
})
