Importing from node_modules with js.Build

Now that Hugo Pipes has JavaScript building via ESBuild, I’m wondering:

Is it possible, using js.Build in templates and import in JavaScript, to load js modules directly from node_modules?

Answering to myself: yes, it’s possible! Path is relative to JS file, e.g.:


import Fuse from "../../node_modules/fuse.js/dist/fuse.basic.esm.min.js";
import Mark from "../../node_modules/mark.js/dist/mark.es6.min.js";
const fuse = new Fuse();


{{- $search := resources.Get "js/search.js" | js.Build (dict "minify" true "target" "es2015") | fingerprint -}}

All imports work perfectly, and the JS bundling is incredible fast (especially if compared with e.g. Babel)!

(Unfortunately, I couldn’t get moment.js to work with any locale via import, but this is not a Hugo problem, anyway.)

import Fuse from "fuse"

Should work and would be more portable. Note that there are some path issues that we intend to fix (esp. when you’re using themes/theme components).

But I agree, it’s incredibly fast and cool.


Thank you, @bep, for the explanation and for Hugo!

By the way, the method suggested by @bep happens to make moment.js work with locales:

import moment from "moment";
import "moment/locale/pt-br";
moment.locale("pt-BR"); /* or moment.locale(document.querySelector("html").lang); */
