# 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 `eslint` (with `tslint` rules and other 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](#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](https://codecov.io/)
- [Code Climate](https://codeclimate.com/)
- [LGTM](https://lgtm.com/)
- [Renovate](https://renovatebot.com/)
- [Snyk](https://snyk.io/)
- [SonarCloud](https://sonarcloud.io/)

None of these are required, but Renovate and Snyk can be very helpful when
dependencies release a security patch.

## External Secrets

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