Import Default From Named Export

Importing default can be nuanced. There are just so many ways to do it.

I like to think of default as a named export with a fixed (non-customizeable) name.

Check out how we can import default like a named export.

import {default as Highlander} from './highlander.js'

The lines below yield identical results.

import Highlander from "./highlander.js";
import { default as Highlander } from "./highlander.js";

Unlike named exports, you can’t import default and use it directly. It must be remaned at import. This is why the more ergonomic option of import MyAlias from "…"; exists.

Use default thru a module alias

We’ve discussed module aliases in past posts. And they have some overlap with the default export.

Check out this totally valid use of Module aliases and default.

import * as Highlander from './highlander.js'

Technically, you’re not using the default keyward because we’re accessing the reference as a property.

Of course, this looks a little strange when used in frameworks like React.

<Highlander.default>…<Highlander.default />

My take

I don’t use default as or ModuleAlias.default() import styles in practice. I just find it helpful to remember how default is exported from modules.

In future posts, we’ll cover two, more ergonomic alternatives capturing both default and named exports.
