Typescript Template

Defaults to module, but exports to CommonJS and ESM.

With documentation, update and release mechanisms and gitlab/github workflows to match;

Defines a 'way' to write jsDocs to optimize the output

Optimized for github in terms of badges. CI is equivalent between Gitlab and Github.

Auto setup on first npm install

Will accept a .token file containing token valid for private npm dependencies, npm and docker registries

Initial Setup

if you use github

create a new project using this one as a template.

clone it git clone <project> and navigate to the root folder cd <project>

If your project has private dependencies or publishes to private npm registries, create an .npmrc containing:

@<scope1>:registry=https://<ADDRESS>.com/api/v4/packages/npm/
@<scope2>:registry=https://<ADDRESS>.<DOMAIN>.com/api/v4/packages/npm/
//<ADDRESS>.<DOMAIN>.com/:_authToken=${TOKEN}
//<ADDRESS>.<DOMAIN>.com/api/v4/groups/<GROUP_ID>/packages/npm/:_authToken=${TOKEN}
//<ADDRESS>.<DOMAIN>.com/api/v4/projects/<PROJECT_ID>/packages/npm/:_authToken=${TOKEN}

Changing:

• to `gitlab` or `github` (or other);
• to your domain if any (if you are using plain gitlab or github use empty and take care to remove the extra .);
• <GROUP_ID> to your project's group id (if any). otherwise remove this line
• <PROJECT_ID> to your project's id

and adding a .token file containing your access token to the private registries na repositories.

Installation

Run npm install (or npm run do-install if you have private dependencies and a .token file) to install the dependencies:

If this is the first time you are running this command it will also:

• update this repository's dependencies to their latest version;
• creates a .token file which you can leave empty unless you have private dependencies or publish to private registries
• delete this 'first run script' file and npm call from the package.json;
• try to commit the updated package.json and deleted files (having ssh access helps here);

Linting

This repo comes with eslint + prettier preconfigured to the default standards

Testing

Preconfigured Jest based testing:

• unit tests under the tests/unit folder;
  • include a default bundle test (helps with circular dependencies and such);
• integration tests under the tests/integration folder;
• stores converage results under workdocs/coverage;
• publishes coverage result to docs;
• ignores cli.ts from coverage since that is an executable file;
• defines the coverage threshold in jest.config.ts;

Releases

This repository automates releases in the following manner:

• run npm run release -- <major|minor|patch|version> <message>:
  • if arguments are missing you will be prompted for them;
• it will run npm run prepare-release npm script;
• it will commit all changes;
• it will push the new tag;

If publishing to a private repo's npm registry, make sure you add to your package.json:

{
  "publishConfig": {
    "<SCOPE>:registry": " https://<REGISTRY>/api/v4/projects/<PROJECT_ID>/packages/npm/"
  }
}

Where:

• <SCOPE> - Is the scope of your package;
• <REGISTRY> - your registry host;
• <PROJECT_ID> - you project ID number (easy to grab via UI in gitlab or by running $("meta[name=octolytics-dimension-repository_id]").getAttribute('content') in the repository page in github) ;

Publishing

Unless the -no-ci flag is passed in the commit message to the npm run release command, publishing will be handled automatically by github/gitlab (triggered by the tag).

When the -no-ci flag is passed then you can:

• run npm run publish. This command assumes :
  • you have previously run the npm run release;
  • you have you publishing properly configured in npmrc and package.json;
  • The token for any special access required is stored in the .token file;

Continuous Integration/Deployment

While the implementationfor gitlab and github are not perfectly matched, they are perfectly usable.

The template comes with ci/cd for :

• gitlab (with caching for performance):
  • stages:
    • dependencies: Installs dependencies (on package-lock.json changes, caches node modules);
    • build: builds the code (on src/* changes, caches lib and dist);
    • test: tests the code (on src/*, test/* changes, caches workdocs/{resources, badges, coverage});
    • deploy:
      • deploys to package registry on a tag (public|private);
      • deploys docker image to docker registry (private);
      • Deploys the documentation to the repository pages;
• github:
  • jest-test: standard install -> build -> test loop;
  • jest-coverage: extracts coverage from the tests;
  • codeql-analysis: Code quality analisys;
  • pages: builds the documentation and deploys to github pages
  • release-on-tag: issues a release when the tag does not contain -no-ci string
  • publish-on-release: publishes to package registry when the tag does not contain the -no-ci string
  • Requires Variables:
    • CONSECUTIVE_ACTION_TRIGGER: secret to enable actions to trigger other actions;
    • NPM_TOKEN: npm/docker registry token

Considerations

• Setup for a linux based environment (Sorry windows users. use WSL... or just change already);
• Setup for node 20, but will work at least with 16;
• Requires docker to build documentation (drawings and PlantUML)

Documentation

The repository proposes a way to generate documentation that while still not ideal, produces verys consitest results.

In the code you see an example on how to properly document each code object, but the overall structure is:

• each package is a @module;
• Classes and Interfaces are categorized into @category and @subcategory;
• All other objects are categorized by @namespace and @memberOf;
• Enums and const are declared as @const and both must describe their properties as @property (when constants are objects);
• Interfaces must declare their methods @method;

There are 3 steps the generating the documentation (automated in CI):

• npm run drawings - generates png files from each drawing in the workdocs/drawings folder and moves them to the workdocs/resources folder (requires Docker);
• npm run uml - generates png files from each PlantUML diagram in the workdocs/uml folder and moves them to the workdocs/resources folder (requires Docker);
• npm run docs - this has several stages, defined under the gulp docs (gulpfile.js):
  • compiles the Readme file via md compile:
    • enables keeping separate files for sections that are then joined into a single file;
    • Allows keeping specific files in the jsdocs tutorial folder so they show up on their own menu;
  • compiles the documentation from the source code using jsdocs:
    • uses the better docs template with the category and component plugins
    • uses the mermaid jsdoc plugin to embue uml diagrams in the docs
    • includes a nav link to the test coverage results;
  • copies the jsdoc and mds to /docs;
  • copies the ./workdocs/{drawings, uml, assets, resources} to ./docs;

The produced docs folder contains the resulting documentation;

Scripts

The following npm scripts are available for development:

• preinstall - will run only on the first install to trigger the dep update. will self delete;
• do-install - sets a TOKEN environment variable to the contents of .token and runs npm install (useful when you have private dependencies);
• flash-forward - updates all dependencies. Take care, This may not be desirable is some cases;
• reset - updates all dependencies. Take care, This may not be desirable is some cases;
• build - builds the code (via gulp gulpfile.js) in development mode (generates lib and dist folder);
• build:prod - builds the code (via gulp gulpfile.js) in production mode (generates lib and dist folder);
• test - runs unit tests;
• test:integration - runs it tests;
• test:all - runs all tests;
• lint - runs es lint on the code folder;
• lint-fix - tries to auto-fix the code folder;
• prepare-release - defines the commands to run prior to a new tag (defaults to linting, building production code, running tests and documentation generation);
• release - triggers a new tag being pushed to master (via ./bin/tag_release.sh);
• clean-publish - cleans the package.json for publishing;
• coverage - runs all test, calculates coverage and generates badges for readme;
• drawings - compiles all DrawIO *.drawio files in the workdocs/drawings folder to png and moves them to the workdocs/resources folder;
• uml - compiles all PlantUML *.puml files in the workdocs/uml folder to png and moves them to the workdocs/resources folder;
• docs - compiles all the coverage, drawings, uml, jsdocs and md docs into a readable web page under ./docs;
