1) Migrate from webpack 4 to webpack 5. This had a lot of breaking changes,
so updated multiple webpack plugins and changed the config accordingly.
2) Replaced iconfont-webpack-plugin with a more maintained webfonts-loader.
3) Replaced deprecated babel-eslint with @babel/eslint-parser.
4) Replaced optimize-css-assets-webpack-plugin with a more maintained css-minimizer-webpack-plugin.
5) Updated all other JS packages and made the required code changes.
Fixes#6207
2) Added server group name while selecting servers in schema diff. Fixes#5500
3) Fixed an issue where two identical tables showing different by schema diff tool. Fixes#5584
Changes include:
1) Remove underscore-string and sprintf-js packages as we were using only %s. Instead, added a function to do the same. Also changed gettext to behave like sprintf directly.
2) backgrid.sizeable.columns was not used anywhere, removed. @babel/polyfill is deprecated, replaced it with core-js.
3) Moved few css to make sure they get minified and bundled.
4) Added Flask-Compress to send static files as compressed gzip. This will reduce network traffic and improve initial load time for pgAdmin.
5) Split few JS files to make code reusable.
6) Lazy load few modules like leaflet, wkx is required only if geometry viewer is opened. snapsvg loaded only when explain plan is executed. This will improve sqleditor initial opening time.
