+You can export types or even specific methods if you are using modern ES6 js or TypeScript.
+```js
+import wiki from 'wikipedia';
+import { wikiSummary, summaryError } from 'wikipedia';
+import { summary } from 'wikipedia';
+
+(async () => {
+	try {
+        let summary: wikiSummary; //sets the object as type wikiSummary
+		summary = await wiki.summary('Batman');
+		console.log(summary);
+        let summary2 = await summary('Batman');//using summary directly
+	} catch (error) {
+		console.log(error);
+		//=> Typeof summaryError, helpful in case you want to handle this error separately
+	}
+})();
+```
+
