Title explains the question. How would you import them both and preserve the d3.\* namespace?

If bundling the modules, I’d include:

```
  export {select, selectAll} from "d3-selection";
  export * from "d3-selection-multi";
  export * from "d3-timer";

```

In my index.js file, assigning one namespace to all the exports. How can I do the same with Observable when it uses something more like CJS syntax for imports?

Seems can just use

```
d3 = require(
           'd3-selection',
           'd3-selection-multi'
         )

```

Note: @tom Might be good to add this to the require tutorial.

Indeed - the Intro notebook overlooked that detail! Thanks for pointing it out, I’ve added a new section under “require’s input” that explains multi-requires.
