Error summary
_freeGlobal appears to be imported at https://github.com/lodash/lodash/blob/master/.internal/nodeUtil.js#L1. It looks like lodash is a dependency of Bluebird (https://github.com/request/promise-core/blob/master/package.json#L36).
If I try to add lodash to the fuzzymatchingjs's dependencies directly, this require for freeGlobal is resolved and the JavaScript is usable in a browser context.

How to fix
- change orders of plugins
Fixed by putting
rollup-commonjs
plugin just afterrollup-plugin-node-resolve
plugin and it is working like a charm! :)Or newer version
putting@rollup/plugin-commonjs
plugin just after@rollup/plugin-node-resolve
plugin
Conclusion
this warning easily fixed by change orders of plugin
full rollup.config.js
working example:
// bundle for browser and ESM module
const resolve = require('@rollup/plugin-node-resolve');
const commonjs = require('@rollup/plugin-commonjs');
const { terser } = require('rollup-plugin-terser');
const json = require('@rollup/plugin-json');
//const typescript = require('@rollup/plugin-typescript');
//const tsconfig = require('./tsconfig.build.json');
//const tsbase = require('./tsconfig.base.json');
const lib = require('./package.json');
const outputFileName = 'sbg-utility';
const name = 'sbg-utility';
const input = './dist/index.js';
const polyfill = require('rollup-plugin-polyfill-node');
/**
*
* @param {import('rollup').RollupOptions} config
* @returns
*/
const buildConfig = (config) => {
/*const tsOpt = Object.assign(tsbase, tsconfig, {
compilerOptions: {
module: 'esnext',
lib: ['es2020', 'dom'],
target: 'es5',
allowSyntheticDefaultImports: true,
skipLibCheck: true
}
});
if (tsOpt.extends) delete tsOpt.extends;*/
// plugins: [typescript(tsOpt)]
const build = ({ minified }) => ({
input,
...config,
output: {
...config.output,
file: `${config.output.file}.${minified ? 'min.js' : 'js'}`
},
plugins: [
json(),
polyfill(),
commonjs(),
resolve({ preferBuiltins: true, browser: true }),
minified && terser(),
...(config.plugins || [])
]
});
return [build({ minified: false }), build({ minified: true })];
};
const defaults = async () => {
const year = new Date().getFullYear();
const banner = `// ${lib.name} v${lib.version} Copyright (c) ${year} ${lib.author}`;
return [
...buildConfig({
output: {
file: `dist/browser/${outputFileName}`,
name,
format: 'umd',
exports: 'default',
banner
}
}),
...buildConfig({
output: {
file: `dist/esm/${outputFileName}`,
format: 'esm',
preferConst: true,
exports: 'named',
banner
}
})
];
};
module.exports = defaults;
then run this config using rollup -c -m
