How to install​

To install JHipster v9.0.0 using NPM:

npm install -g generator-jhipster

It is also available using the JHipster Docker image, as it is automatically built from our source code.

How to upgrade​

Automatic upgrade

For an automatic upgrade, use the JHipster upgrade sub-generator on an existing application:

Upgrade your version of JHipster:

npm update -g generator-jhipster

And then run the upgrade sub-generator:

jhipster upgrade

You can also use the migrate blueprint for more advanced upgrade features.

npm i -g generator-jhipster-migrate
jhipster-migrate

Manual upgrades

For a manual upgrade, first upgrade your version of JHipster with:

npm update -g generator-jhipster

If you have an existing project, it will still use the JHipster version with which it was generated. To upgrade your project, you must first delete its node_modules folder and then run:

jhipster

You can also update your project and all its entities by running:

jhipster --with-entities

You can also update your entities one-by-one by running again the entity sub-generator, for example if your entity is named Foo:

jhipster entity Foo --single-entity
