test-locally.sh

# This script is meant to help the local development of the core design system by building child & applications to test local changes

# PRE-REQUISTES
# 1. This script assumes that this project, both child systems, and any application project all share a parent directory on your machine.
#    For example, your directory structure should be similar to
#       projects/
#           design-system/
#           mgov-design-system/
#           hcgov-design-system/
#           application-to-test/

# 2. Ensure that child design system projects are looking at local version of the core DS by updating the package.json so that the following dependencies look like this:
#   "@cmsgov/design-system": "file:../design-system/packages/design-system",
#   "@cmsgov/design-system-docs": "file:../design-system/packages/design-system-docs",
#   "@cmsgov/design-system-scripts": "file:../design-system/packages/design-system-scripts",

# 3. Ensure that application project is pointing at local version of child design system by modifying the package.json so that the following dependencies look like this:
#   "@cmsgov/ds-healthcare-gov": "file:../hcgov-design-system",
#       or
#   "@cmsgov/ds-medicare-gov": "file:../mgov-design-system",

## 4. Note, this script assumes you use nvm to manage node versions

# USING THIS SCRIPT
# In the root directory of the design-system project, run `./test-locally.sh`
#   This will install dependencies and run the core DS.
#   Then, it will navigate to the child DS project. It will remove node_modules, install dependencies & build child system.
#   Then, it will navigate to an application project. It will remove node_modules, install dependencies & build the application.

# This script will try to use the default variables defined in this file, but you can override these for additional testing.
# For example, if you want to test the hcgov child system, when the default CHILD_DS_NAME variable is mgov child system, you can:
#   1. Update the CHILD_DS_NAME variable in this file
#   2. Run `./test-locally.sh -c hcgov-design-system`

# Similarly, if you want to change the application path your are testing with, you can:
#   1. Update the APP_NAME path variable in this file
#   2. Run `./test-locally.sh -a [directory name of application]`
#     a. If you only want to test in child systems and not in an application, you can run `./test-locally.sh -a ""`
