If you want to require a file attachment, it’s:

```auto
foo = require(await FileAttachment("foo.js").url())

```

This assumes that your file (foo.js) is compatible with AMD ([d3-require](https://github.com/d3/d3-require)). If you want to load a standard ES module instead, you can use dynamic import:

```auto
foo = import(await FileAttachment("foo.js").url())

```
