NestJS Tutorial Repository

Repository will be separated into server and client directory for NestJS backend and Angular frontend resepctively.

This repository houses the Project's backend written using NestJS

NSwag: Nswag allows us to generate API Calls to our Backend on our Frontend in forms of Functions. The abstraction of HttpClientModule takes place in the generated file.
Steps:
1. cd ./server & npm i to install all dependencies for Server side
2. Have an instance of MongoDB running (mongod). If you use an IDE like WebStorm, I have a script called: mongo:local that is going to run mongod subsequently so you can setup a Compound Run Configuration with start:dev and mongo:local to start the Backend with ease.
3. npm run start:dev to start the server
Note: If there's issue connecting to local MongoDB and you make sure that you already have mongod running, go to config/default.ts and check if the MONGO_URI is correct.

This repository houses the Project's frontend written using Angular 6

Ant Design: The components design is by AntDesign (https://ng.ant.design/docs/introduce/en). I really like the subtle looks of AntDesign.
Steps: npm i to install all the dependencies then just start the application with ng serve
Note: Might be worth it to take a look at proxy.conf.json and how I setup the CLI to use the proxy file when serving so that we can call our backend on localhost:3000. This is so-called Cross Domains Request and our backend does not have CORS setup. Proxy will help us making the requests from 4200 to 3000.

Docker is supported.

Branch: docker
Steps: Just clone the repository, check out docker branch then from root directory, run docker-compose up and Docker will take over.
Note: Angular application will be served by NGINX on localhost; Nest application will be running on localhost:3000; cAdvisor which monitors our containers will be running on localhost:8080. Again, it's worthwhile to explore the Dockerfile in both client and server directory; also nginx.conf and docker-compose.yml to get the gist of how Docker and Docker Compose work.

P.S: Pull Requests, Contributions are most definitely welcomed :)

d3.nest 详解

d3.nest可以分组数据在进行数据分析时Grouping data是一个很重要的能力 .通常，我们需要将数据按照某个类别进行打散，并查找和统计每个组的具体细节。 D3 包括强大的d3.nest 功能，可以通过极小量的代码构造分组。 Nest 基础用户来决定这个嵌套多少层。跟很多GROUP_BY概念有点不同，其中只允许有嵌套一个级别。例如，我们有如下的 CSV 格式文件 “expenses
