pie-cli

Install

npm install -g pie

Developer install

git clone [email protected]:pie-framework/pie-cli.git
cd pie-cli
npm install
npm run build
npm link

# pie-cli executable now points to /bin/pie-cli

Usage

pie --help|-h

Developing

If you want to play with the cli while developing you can watch the src, then link the repo so you can invoke the cli

npm link
npm run dev # runs -> 'gulp dev'
# in some other dir
pie --help

Debugging

To debug typescript you'll need to generate the sourcemaps. gulp-typescript doesn't do this at the moment, so we use tsc instead.

• run npm run source-maps
• run node --debug-brk --inspect $(which pie) ....

Windows debugging: node.exe --debug-brk --inspect "C:\Users\Edward Eustace\AppData\Roaming\npm\node_modules\pie\bin\pie" --version

Node is now running in debug mode on 5858 so boot up a debugger. Visual Studio Code has nice typescript debugging support. In VS:

• add a breakpoint to the ts src file you want to debug.
• press F5.
• If you have no debug config it'll ask you to add one.
• Add the following:

{
  "type": "node",
  "request": "attach",
  "protocol": "inspector",
  "name": "Attach to Process",
  "port": 9229,
  "outFiles": ["${workspaceRoot}/lib/**/*.js"],
  "sourceMaps": true
}

• select this runner and the app will start and hit your breakpoint.

Contributing

If you are commiting a code change that is worthy of being included in the release information, write your commit message using the angular commit conventions outlined here. These commit formats will automatically be included in the release notes.

Tests

Unit

npm test

Integration

The integration tests are slower than the unit tests because of all the npm install commands. You'll probably want to run the 1 at a time like so:

mocha --require test/init test/integration/framework-support/support-module-test.js

or to run an individual test:

./node_modules/.bin/mocha  --require test/init.js  test/integration/init.js test/integration/cli/install-test.js

--require test/init - inits babel and the logger.

To run them all:

npm run it

Test Coverage

npm install -g nyc
nyc npm test

Build

npm run build

Release

This creates a new github release from the develop branch:

Be sure to only use npm for install - if you use yarn you may get publishing errors like: TypeError: log.gauge.isEnabled is not a function.

git checkout master
git merge develop
npm run release

Architecture Notes

When you run any of the commands that generate/serve js you are running one or more webpack builds via an App. For example pie info uses the InfoApp which has a serve function. This method will run an install then run a server that will make use of webpack-dev-middleware.

The high level flow is: cmd -> install -> prepare webpack config(s) -> run webpack build | run webpack-dev-middleware.

.pie - build directory

When you install, you are installing the dependencies for your pie package. This happens in a directory called .pie that is relative to the pie item directory.

Inside the .pie directory is:

• package.json - the install generated package.json that lists the pies that are dependencies
• .controllers - the controllers install directory for controller related dependencies
• .configure - the configure install directory for configure related dependencies.
• *.entry.js - entry files for the given app type
• *.config.js - webpack config js files (useful for debugging builds)

build support

The webpack builds inside .pie make use of some pre-installed support directories that are located in pie-cli/support. They are npm packages that get installed along with pie-cli. Their node_modules directories are added to the webpack resolve.modules and resolveLoader.modules arrays.

They also contain rules that can be added to a webpack config. All the apps in pie-cli make use of any rules in the default support packages.

We do this to speed up intallation by only having to install these once. It gives greater control over supporting libs are added to the webpack build.

The support package is a standard npm package and we hope to enable the inclusion of external support packages via command line options for custom builds.

legacy automatic support

The cli automatically supports [email protected] and less. Note that this support will be up for review shortly and may be removed.
