Webpack-cli - Error on start with node 14

[Gaetanbrl]

Hi,

Versions

Node v14.16.1
Npm 6.14.12

issue

Npm start return webpack-cli error :

1% setup initialize[webpack-cli] TypeError: cli.isMultipleCompiler is not a function
1 --hot --inline --content-base .`

This seems to come from webpack-cli and webpack packages version in master branch :

MapStoreExtension/package.json

Lines 112 to 114 in 8ae58de

	"webpack": "5.9.0",
	"webpack-bundle-size-analyzer": "2.0.2",
	"webpack-cli": "4.9.0",

$ webpack --version
webpack: 5.9.0
webpack-cli: 4.9.0       
webpack-dev-server 3.11.0

After upgrade webpack-cli all work fine :

npm install [email protected]

Fwiw, was experiencing the same issue with node v12.22.12 when trying npm start on https://github.com/georchestra/mapstore2-cadastrapp, changing webpack-cli to 4.10.0 and running npm install fixed it.
