Could you link to an example notebook that illustrates the issue? ---

As I understand it, there’s less of a reason to use Axios now that the [Fetch standard](https://fetch.spec.whatwg.org) is supported by modern browsers. Perhaps you are running into CORS issues? Have you read the introduction to data notebook? > **[Introduction to Data](https://beta.observablehq.com/@mbostock/introduction-to-data)** > > An Observable notebook by Mike Bostock. ---

I need data from remote js file, like this “[http://lol.qq.com/biz/hero/champion.js](http://lol.qq.com/biz/hero/champion.js)”, I want to load it directly instead of saving it to local. Sorry, I am a new developer, maybe there is better way to implement. ---

Sounds like you need a CORS proxy. You can’t fetch directly from an HTTP site (HTTPS is required) and the server must have [CORS enabled](https://enable-cors.org). You can try the demo instance of CORS-Anywhere to start. > **[Rob--W/cors-anywhere](https://github.com/Rob--W/cors-anywhere)** > > CORS Anywhere is a NodeJS reverse proxy which adds CORS headers to the proxied request. - Rob--W/cors-anywhere ---

For what it’s worth, I tried to use a few different CORS proxies to load your data, but without success: > **[Loading data from external JS file / Observable](https://beta.observablehq.com/d/16c17d9e954eada7)** > > A better way to code. I couldn’t get CORS-anywhere to work at all. The other two proxies send the JS file with the wrong MIME Content-type: [cors.io](http://cors.io) sends it as `text/html` and codetabs sends it as `text/plain`. ---

This might be a bit confusing at first because the file isn’t data - it’s JavaScript code. So solving CORS, using axios, and other steps aren’t directionally right. You can, however, achieve what you want to do: ``` require("https://lol.qq.com/biz/hero/champion.js").catch(() => window.LOLherojs) ``` This uses `require()`, our method for including code, but since `champion.js` doesn’t implement UMD or any sort of ‘module definition’ standard and instead just leaves a variable behind, we catch that variable (what I call the ‘global leaks pattern’ in the module debugger). (The other minor quirk is that I changed the URL from `http://` to `https://`. [qq.com](http://qq.com) supports both, but http:// won’t work with Observable or any SSL website). ---
