Vite: Uncaught SyntaxError: import not found: default N3Lexer.js:3:7

KonradHoeffner commented 2 years ago

Has anyone successfully used this library in the browser with Vite? In my own attempt using vite 2.6.4, there was first an "global is not defined" error but after fixing that, using the following vite.config.js, I now get the error Uncaught SyntaxError: import not found: default N3Lexer.js:3:7.

vite.config.js

import nodeGlobals from 'rollup-plugin-node-globals'

export default {
    sourcemap: true,
    plugins: [nodeGlobals(),],
    optimizeDeps: {exclude: ["rdflib"]},
    build: {
        target: "esnext",
        rollupOptions: {
            output: {
                assetFileNames: "assets/[name][extname]",
            },
        },
    },
};

Code

import * as rdf from "rdflib";
const RDF = rdf.Namespace("http://www.w3.org/1999/02/22-rdf-syntax-ns#");

Error from npm run build

When using import { Namespace, graph, sym, parse, SPARQLToQuery } from "rdflib"; instead of import * as rdf from "rdflib", it still doesn't work with npm run dev, however it works with npm run build && npm run preview on Vite! They scripts are defined in package.json as:

    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview",

The problem still occurs with Vite v2.9.5 and rdflib 2.2.19.

MWE

$ npm create vite@latest
$ cd vite-project
$ npm install rdflib rollup-plugin-node-globals

Then create vite.config.js as defined in the original post and add the following to main.js:

import * as rdf from "rdflib";
const RDF = rdf.Namespace("http://www.w3.org/1999/02/22-rdf-syntax-ns#");

Then run npm run build:

> vite-project@0.0.0 build
> vite build
