This repository creates a local npm registry provided by nexus running in a local docker image and it should help to reduce internet traffic and built time by downloading redundant npm dependencies.
It contains an extension of the Dockerfile of Nexus3 for Docker's.
-
Install Docker.
-
Download the docker-nexus-npm-registry image from public Docker Hub Registry
$ docker pull sebak/nexus_npm_registry_vaadinor, you can build an image from the given Dockerfile:
$ docker build -t="npm-registry" .
$ docker run -dit -p 8081:8081 npm-registry
To link npm to your local registry add a configuration to your local npm
$ npm config set registry http://localhost:8081/repository/npmjs-org/
or add frontend-maven-plugin to your project pom. You can find an example project with a proper configuration in the vaadin-example folder.
After setting up the docker image you need to compile a vaadin project on your machine with
$ mvn install -Pproduction --file vaadin-example/pom.xml
TIP: You could add "-Dvaadin.version=<vaadin version no.>" to download the dependencies for a specific vaadin version. Available version numbers of the Vaadin framework can be found here.
Beware, if you want to add web-components to the project later, which are not part of the default web-component set, you need to have a internet connection available to download and add them to your local npm-regsitry.
To check the content of the npm registry you can go to localhost:8081 and login with username "admin" and password "admin".
