JHOVE2020

Getting Started

JHOVE 2020 is an Electron application.

Pre-requisites

You'll need the following for developing Electron apps:

• NodeJS as a JavaScript runtime v12.14.1-LTS; and
• Node Package Manager (NPM).

Development environment

Electron, Node and their dependencies can make for a complicated stack. To avoid contaminating a development environment it's best to use Node virtual environments. This Python utility creates discrete Node environments with their own installation directories and shared libraries. While NodeEnv can be installed globally using Python's pip package manager it can also be installed in a Python virtual environment. This means running a Node virtual environment within a Python virtual environment but avoids unnecessary local installations.

You'll need:

• Python (2.6+ or 3.3+)
• Virtualenv for Python virtual environments

A virtual development environment can then be set up, e.g. fi:

$ virtualenv .venv
$ source .venv/bin/activate
(.venv) $ pip install nodeenv
(.venv) $ nodeenv --version
1.3.4

NodeEnv

To get a list of available node.js versions:

(.venv) $ nodeenv --list

To install and activate a node.js 12.14.1-LTS environment:

(.venv) $ npmnodeenv --node=12.4.1 .node-12.4
(.venv) $ source .node-12.4/bin/activate
(.node-12.4) (.venv) $ node --version
v12.14.1
(.node-12.4) (.venv) $ npm --version
6.13.4

Installing node dependencies

From the project root directory type npm install.
