Fix rollup eval warning

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.

some looks error logs

(!) Use of eval is strongly discouraged

How to fix

change orders of plugins

Fixed by putting rollup-commonjs plugin just after rollup-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');
