TypeScript + lerna + yarn monorepos FTW Paris TypeScript #10
10/10/2017 1
Me, myself & I Paul Souche Front End developer @S_A_N_T_E_C_H
In love with TypeScript since 2014 @paul.souche paulsouche @paulsouche 2
Multi repos : why ? - Monoliths no more -
Build only the necessary - Clearer subversion history - Easier revert - 1 app > 1 repo - 1 service > 1 repo... 3
Multi repos : but ... - Switch project all the
time - Sequential builds - Evergreen anti pattern - Dependencies - Versioning - Features branch 4
- Build everything everytime - Build order - Subversion Conflicts
- Licenses 5 Did you said monorepo?

Lerna << Lerna is a tool that optimizes the workflow
around managing multi-package repositories with git and npm >> 8
Prerequisites 9
Lerna project structure - lerna import <path to package> -
lerna bootstrap 10
What it does 11
Demo 12
Yeah… But ? - devDependencies are the same so lerna
bootstrap could be very slow for more packages (cache) - Build is sequential 13
yarn workspaces 14
Lerna config 15
What happen to the structure 16
Demo 17
Build 18 - Several flags such as --parallel I won’t
talk about - Bash is always the answer for uncommon problems
That’s all folks THANKS References Lerna Yarn workspaces Demo 19
