If your project has a package.json file, we will install
the dependencies listed in this file as part of the deployment process. Please note
that we use the production flag with npm (npm install --production)
which means that the dependencies listed under devDependencies
are not installed. In case you'd like to install dependencies listed in
devDependencies, they need to be moved to
dependencies field of package.json
When you deploy your app via git deployment the modules are installed installed at the end of the deployment process.
In case you use FTP deployment, during the
restart of your app we detect if any changes have been uploaded and trigger rebuild of your
app. At the end of the rebuild process we install all modules listed in package.json.
We cache modules installed from package.json so that any consequent builds are
faster. In case you would like to disable the cache, you can set environment variable
MODULES_CACHE=0 for your app which will disable the cache for future builds.
