[Angular 10 + NgRx + Nest.js] Create project

Intro

This time, I added server-side.
I choosed Nest.js because I love TypeScript and I had been interested in using TypeScript in server-side programming.

Environments

  • Angular ver.10.0.2
  • @ngrx/store ver.9.2.0
  • @ngrx/effects ver.9.2.0
  • @nestjs/ng-universal ver.2.0.1

Couldn't add @ngrx/store into the Angular 10 project

First, I created an Angular project and tried adding @ngrx/store into it. And I got an error. 
Installing packages for tooling via npm.
Installed packages for tooling via npm.
The package that you are trying to add does not support schematics. You can try using a different version of the package or contact the package author to add ng-add support.
According to the issue below, I should add "@latest". 
npx ng add @ngrx/store@latest
Because if I didn't add it, the @ngrx/store version was too low. 


Though I didn't know I should add "@latest" into "@ngrx/effects" or not, I installed it by "npx ng add @ngrx/effects@latest"

Add a Nest.js project

I added a Nest.js project by "@nestjs/ng-universal". 


 It was for Server-Side Rendering for Nest.js. After "ng add" command, I input the Angular project name. 
npx ng add @nestjs/ng-universal

Run the project (Failed)

I could run the project by "npm run serve" and access the page from "localhost:4200". But when I opened the page, I got an error. 
...
[Nest] 12736   - 07/08/2020, 1:04:45 AM   [ExceptionsHandler] Cannot read property 'indexOf' of undefined +28479ms
TypeError: Cannot read property 'indexOf' of undefined
...
According to the issue below, I set "liveReload" false. 

  TypeError: Cannot read property 'indexOf' of undefined · Issue #188 · nestjs/ng-universal · GitHub

server/app.module.ts


import { Module } from '@nestjs/common';
import { AngularUniversalModule } from '@nestjs/ng-universal';
import { join } from 'path';

@Module({
  imports: [
    AngularUniversalModule.forRoot({
      viewsPath: join(process.cwd(), 'dist/browser'),
      bundle: require('../server/main'),
      liveReload: false
    })
  ]
})
export class ApplicationModule {}

Show a white page

Though I could avoid the error, I couldn't watch the Angular project page but a white page. Because the properties of "AngularUniversalOptions" were changed, I couldn't use "bootstrap" like README.md. 


 But when I accessed "localhost:4200/index.html", I could watch the Angular project page.

So I thought I should set static files like last time. According to the README.md, I could use "templatePath". But it might not work...

server/app.module.ts


import { Module } from '@nestjs/common';
import { AngularUniversalModule } from '@nestjs/ng-universal';
import { join } from 'path';

@Module({
  imports: [
    AngularUniversalModule.forRoot({
      viewsPath: join(process.cwd(), 'dist/browser'),
      bundle: require('../server/main'),
      liveReload: false,
      templatePath: join(process.cwd(), 'dist/browser/index.html'),
    })
  ]
})
export class ApplicationModule {}
Should I redirect by "@nestjs/serve-static" or by routing?

Add @nestjs/serve-static

In this time, I choosed installing "@nestjs/serve-static" to show "index.html". 
npm install --save @nestjs/serve-static

server/main.ts


import { NestFactory } from '@nestjs/core';
import { ApplicationModule } from './app.module';
import { NestExpressApplication } from '@nestjs/platform-express';
import { join } from 'path';

async function bootstrap() {
  const app = await NestFactory.create(ApplicationModule);
  app.setGlobalPrefix('api');
  app.useStaticAssets(join(__dirname, '..', 'browser'));
  await app.listen(4200);
}
bootstrap();

[Angular][ASP.NET Core] Upload chunked files

Intro I wanted to send files to Web application (made by ASP.NET Core). If the file size had been small, I didn't need do any special things. But when I tried to send a large file, the error was occurred by ASP.NET Core's limitation. Though I could change the settings, but I didn't want to do that, because I hadn't known the file sizes what would been actually using. So I splitted the data into chunks first, and sent them. After receiving all chunks, I merged them into one file. There might be some libraries or APIs (ex. Stream API) what did them automatically, but I couldn't find them. What I did [ASP.NET Core] Make CORS enabled [Angular] Split a large file into chunks [Angular][ASP.NET Core] Send and receive data as form data [ASP.NET Core] Merge chunks into one file [ASP.NET Core] Make CORS enabled Because the client side application(Angular) and the server side application(ASP.NET Core) had been separated, I had to make CORS(Cross-Origin Requests) ...

[Ubuntu] Install Docker, PostgreSQL(From DockerHub), PgAdmin4 + SELECT ALL

Intro I build development of PostgreSQL environment on Ubuntu this time. Because I haven't wanted to install PostgreSQL directly, I use Docker to install it. After installing them, I will try some SQL. Build development environments Docker According to the documents, I add repository and install "docker-ce", "docker-ce-cli", "containerd.io" Get Docker Engine - Community for Ubuntu | Docker Documentation When I had installed "Docker for Windows" on Windows, it had the GUI application.
