Rollup Template

This project contains the configuration and build scripts for most of my Typescript projects, with scripts to create a new project and keep existing ones up-to-date. Even this readme is a template for others.

Features

• build scripts with make
• build pipeline with gitlab
  • update github commit status
  • publish docker images from branches & tags
  • publish npm packages from tags
• bundled with rollup
• type checked with typescript
• style checked with tslint (and plugins)
• tested with mocha (with source map support and helpers for async leak tracking)
• code coverage measured with nyc
• changelog generated with standard-release

Intentionally Omitted Features

• everything frontend: React, CSS, etc
• heavy backend libraries: ORMs, etc

Usage

To Setup

To create a new repository from this template:

• create your new repo on Github & Gitlab (your server or Gitlab.com)
• git clone git@github.com:ssube/rollup-template.git your-project
• cd your-project
• git remote add github git@github.com:yourname/your-project.git
• git remote add gitlab git@gitlab.com:yourname/your-project.git
• set up repository mirroring in Gitlab
• set up some maintenance bots
• make git-push
• install your dependencies
• write some code

To Build

Once your project is set up:

• make to bundle and test
• commit
• make git-push

The git-push target pushes to Github first, to avoid conflicts with changes from bots and other contributors.

To Release

When your project is ready to release:

• make release-dry to make sure your changelog and options look right
• make release

Additional options can be passed with the RELEASE_OPTS variable. Frequently used options include --release-as minor and --prerelease.

External Services

This template works with or expects a few external services, namely a Gitlab CI server (self-hosted or using Gitlab.com).

Maintenance Bots

Good tests and clever bots can eliminate the most painful parts of project maintenance. This repository is configured to work with:

• CodeCov
• Code Climate
• LGTM
• Renovate
• Snyk
• SonarCloud

None of these are required, but Renovate and Snyk can be very helpful when dependencies release a security patch (and even more so when they decline).

External Secrets

This template expects a few secrets to exist in the environment, including tokens for the external services.

Name	Description
CC_TEST_REPORTER_ID	code climate ID
CODECLIMATE_SECRET	code climate token
CODECOV_SECRET	codecov token
DOCKER_SECRET	docker config, required for publishing images
GITHUB_SECRET	github.com token, required for publishing status
NPM_SECRET	npmjs.com token, required for publishing npm packages
SONAR_SECRET	sonarcloud token

Secrets should be provided as environment variables, with the secret value base64-encoded.
