Building angular-datatables

Prerequisites

Node.js and npm are essential to Angular development.

Get it now if it's not already installed on your machine.

Verify that you are running at least node v10.x.x and npm 6.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors.

We recommend nvm or n for managing multiple versions of node and npm.

Clone this project

Clone this repo into new project folder (e.g., my-proj).

git clone  https://github.com/l-lin/angular-datatables
cd angular-datatables

Install npm packages

See npm, n and nvm version notes above

Install the npm packages described in the package.json and verify that it works:

Attention Windows Developers: You must run all of these commands in administrator mode.

npm install
npm run build

The npm run build command compiles the library,

npm scripts

We've captured many of the most useful commands in npm scripts defined in the package.json:

  • npm run tsc - runs the TypeScript compiler once.
  • npm run tsc:w - runs the TypeScript compiler in watch mode; the process keeps running, awaiting changes to TypeScript files and re-compiling when it sees them. with excellent support for Angular apps that use routing.
  • npm test - compiles, runs and watches the karma unit tests
  • npm build - compiles and generate the JS files

Updating dependencies version

We use npm-check-updates to update automatically the dependencies:

npm i -g npm-check-updates
ncu -u
rm -rf node_modules && npm install

If you want to update angular, use the cli:

ng update @angular/cli @angular/core

Testing

These tools are configured for specific conventions described below.

It is unwise and rarely possible to run the application, the unit tests, and the e2e tests at the same time. We recommend that you shut down one before starting another.

Unit Tests

TypeScript unit-tests are usually in the src folder. Their filenames must end in .spec.

Look for the example src/angular-datatables.directive.spec.ts. Add more .spec.ts files as you wish; we configured karma to find them.

Run it with npm test

That command first compiles the application, then simultaneously re-compiles and runs the karma test-runner. Both the compiler and the karma watch for (different) file changes.

Shut it down manually with Ctrl-C.

Test-runner output appears in the terminal window. We can update our app and our tests in real-time, keeping a weather eye on the console for broken tests. Karma is occasionally confused and it is often necessary to shut down its browser or even shut the command down (Ctrl-C) and restart it. No worries; it's pretty quick.

The HTML-Reporter is also wired in. That produces a prettier output; look for it in ~_test-output/tests.html.

Deploying the documentation to Github Pages

Run deploy-doc.sh to deploy the documentation to the Github Pages

You may need to have the following:

  • git
  • have the basic commands in your OS
./deploy-doc.sh <version>

Release

# this will create a new version and push to remote repository
npm version [<newversion> | major | minor | patch]

# examples
# create a patch version to publish fixes to the package
npm version patch
# provide a commit message ('%s' will be replaced by the version number)
npm version patch -m "chore: release %s"
# create a minor version to publish new features
npm version minor
# create a major version to follow Angular major version
npm version major
# more control to the version to set
npm version 8.3.2

Then go to the release page and manually create a new release. There is an automatic Github action that publishes automatically to NPM repository.

Angular Schematics

To build the schematics, issue the following command:

npm run schematics:build

Testing

To test schematics, you will need to setup verdaccio, deploy the lib locally in your machine, then install it via ng add in an Angular project.

Steps

  1. Install verdaccio

    npm install -g verdaccio

  2. Start verdaccio server on a terminal or (command prompt if on Windows) by running:

    verdaccio

  3. Setup an account in verdaccio so you can publish the library on your machine:

    • Run npm adduser --registry=http://localhost:4873
    • Give a username, password and an email address to create an account in verdaccio.

  4. Now, publish the library to verdaccio by running the command:

    npm publish angular-datatables --registry http://localhost:4873

  5. Create an empty Angular project like:

    ng new my-demo-project

  6. Install angular-datatables to this demo project by running:

    ng add --registry=http://localhost:4873 angular-datatables

Notes

  1. The --registry flag informs npm to use verdaccio instead of NPM's registry server.

  2. If you're facing issues with ng add not grabbing code from verdaccio, try setting npm registry endpoint to verdaccio like:

    npm set registry http://localhost:4873

  3. Do remember to reset step 2 or else npm will stop working whenever verdaccio is offline!

    npm set registry https://registry.npmjs.org
