Add schematics for create empty kaufman-bot applications and library in Telegram bot on NestJS

#kaufmanbot #schematics #nx #nestjs

Links

https://github.com/EndyKaufman/kaufman-bot - source code of bot

https://telegram.me/KaufmanBot - current bot in telegram

https://github.com/kaufman-bot/schematics-example - project generated with @kaufman-bot/schematics

Description of work

In the current post, I'm copying the NestJS schemas for building apps and libraries, and after a lot of modifications, I'll make the schemas for building kaufman-bot apps and libraries.

Create new libraries

Create new library for schematics

npm run nx -- g lib schematics

endy@endy-virtual-machine:~/Projects/current/kaufman-bot$ npm run nx -- g lib schematics

> kaufman-bot@2.2.2 nx
> nx "g" "lib" "schematics"

CREATE libs/schematics/README.md
CREATE libs/schematics/.babelrc
CREATE libs/schematics/src/index.ts
CREATE libs/schematics/tsconfig.json
CREATE libs/schematics/tsconfig.lib.json
UPDATE tsconfig.base.json
CREATE libs/schematics/project.json
UPDATE workspace.json
CREATE libs/schematics/.eslintrc.json
CREATE libs/schematics/jest.config.js
CREATE libs/schematics/tsconfig.spec.json
CREATE libs/schematics/src/lib/schematics.module.ts

Append logic for schematics

Remove not need files

rm -rf libs/schematics/src/lib

Clone nrwl nx repository

git clone git@github.com:nrwl/nx.git

endy@endy-virtual-machine:~/Projects/current/kaufman-bot$ git clone git@github.com:nrwl/nx.git

Copy-past logic

Copy nest schematics to kaufman-bot libs

cp -Rf ./nx/packages/nest/** ./libs/schematics
