Configure local npm to use the DNN public repository
From the command line, the following command must be executed:
npm config set registry https://www.myget.org/F/dnn-software-public/npm/
Installing a package from the private repository
To install a package, execute the regular npm command:
npm install packagename
This will search the package in the private repository, and if not found, it will then use the public npm repository
Compiling a package
To compile a package from the source, it is needed to install all its dependencies in the package folder
cd package
npm install
Then the build script should be run to generate the compiled js in the lib subfolder
npm run build
Note:
Yarn is another dependency management tool that can be used for building these packages. If you prefer to use this tool instead of npm, then you need only to replace the npm with yarn in the various commnads above.
