Let downstream application decide about transpiling and polyfills

[StefanBrand]

General information

• json-editor version: 2.13.1

Expected behavior

Bundle in downstream application is responsible for transpiling. json-editor does not bundle all of core-js. Bundle size of downstream application decreases.

Actual behavior

All of core-js is bundled with json-editor, bundle is the main entry point. Downstream application is bloated with polyfills that are not needed.

Steps to reproduce the behavior

1. npx webpack --config config/webpack.prod.js --profile --json > stats.json && npx webpack-bundle-analyzer stats.json dist -> Parsed size is 515kB
2. remove babel-loader from webpack.common.js
3. npx webpack --config config/webpack.prod.js --profile --json > stats.json && npx webpack-bundle-analyzer stats.json dist -> Parsed size is 265kB

Workaround in downstream application

Import JSONEditor like this: import { JSONEditor } from "@json-editor/json-editor/src/core.js";

Solution

Change

json-editor/package.json

Line 6 in e3f8df6

"main": "dist/jsoneditor.js",

-  "main": "dist/jsoneditor.js",
+  "main": "src/core.js",
