Challenges in dev env

Every project, every version requires different environment;

Setup dev environment is cumbersome

➥

Use incomplete environment

Use shared environment

➥

Success in one environment but fail in another

Lightweight

Quickly setup

by one command, in one minute

$ git clone <repo>
$ ./dev_up

Reproducible

Everything is declared inside the Git repo

⁓

Bring up containers which form a consistent environment for development and test

Portable

Windows / Linux / macOS

PC / IT-Hub Machine / Lab Machine

⁓

Only requirement: Docker is installed

Fully automated build process

Install dependencies ➭ preset update

➭ code re-format ➭ lint (code-checking)

➭ compile ➭ test

$ yarn test

Project standard preset

Covers whole software dev lifecycle:

editor setting / git setting / code style / code check /

build workflow / unit test / CI setup / release packaging

⁓

Infrastructure as code

Automatic check & update

• A util has been created to apply preset on a project

• Release new preset package on changed

• Auto update to latest preset on entering dev environment

$ npx -p mrm -p @ses/mrm-preset mrm all \
      --preset @ses/mrm-preset
