Nx Monorepo Typestack Web App

Notable app features

End to end typed
Sane defaults
Workspace management
Enforceable static workspace dependency isolation (internal libs/apps cant inherit classes from other specified)
Dependency graph
Auto-code-gen on backend from schemas
Auto-code-gen on frontend from auto-generated backend endpoints
Auto-code-gen of boilerplate for libraries, apps, react components and more
Frontend: NextJs, Tailwind, URQL, GraphQL Codegen
Backend: Docker, PostgreSQL, Nest, Fastify, GraphQL,Prisma, Mercurius, Class-transformer, Class-validator

Steps to build the app

Setup backend

A backend workspace with:

NodeJs, 100% typescript and typed
Postgresql db
GraphQL
Docker-compose for db migrations
Prisma database ORM to handle migrations, view database in web browser and more etc
Auto-generated graphql endpoints with validation via prisma
Fastify server instead of express for speed (Over 3x faster than expressJS @ 50KTPS+)
Mercurius, a graphql adapter for fastify
Basic CORS support using fastify builtin
Sane http header security policy defaults via helmet, auto-disabled in dev mode

#Install basic modules needed for backend using
npx create-nx-workspace my-full-stack-app --preset=nest --tags "scope:my-backend"
npm i @nestjs/platform-fastify @nestjs/graphql @nestjs/mercurius graphql mercurius
npm uninstall @nestjs/platform-express #replace express with fastify


#Set up app module ts to use mercurius/graphql and swap express for fastify [app.module.ts] [main.ts]

Setup Frontend

A frontend workspace with:

NextJS
Auto-code-gen of react hooks to fetch data from graphql
End to end typed
Serverside rendering of database queries

#Install nextjs using nx to generate the workspace, selecting css, or other option if preferred
npm i --save-dev @nrwl/next
npx nx g @nrwl/next:app my-frontend --tags "scope:my-frontend"


#Install graphql frontend client
npm i urql
#NOTE: After installing urql I got upstream dependency conflict. Possible solutions are..
#Use legacy flag, I chose to use this and stick with npm for now, either way the same problem persists, yarn just hides it better
#I chose to update my justfile so we can run 'just install $package' and worry about dependency conflicts later without forgetting about it
npm install --legacy-peer-deps
#Or switch to yarn, which tends to handle this issue better without crashing (also fixed issue for me)
rm package-lock.json && yarn install


#Install client side graphql code generation modules
npm i @graphql-codegen/cli @graphql-codegen/near-operation-file-preset @graphql-codegen/typed-document-node @graphql-codegen/typescript @graphql-codegen/typescript-operations @graphql-codegen/typescript-urql graphql-codegen


#Install concurrently which we will use to run backend and frontend in one command during development
npm i --save-dev concurrently


#Set up scripts in package.json to run both at once [package.json]
"start:dev": "env-cmd -f .local.env concurrently --kill-others \"npm:db:up\" \"npm:dev:my-frontend\" \"npm:dev:my-backend\" ",

npm run start:devtools

Setting up Tailwind css

Install tailwind using the builtin NX generator.

I chose to install manually, so that we could define some colours, and create a global config. But the automatic setup is what I might use next time. See nx docs for ref here

npx nx g @nrwl/next:setup-tailwind --project=my-frontend

Installing manually

npm i tailwindcss@latest postcss@latest autoprefixer@latest @tailwindcss/typography

cd apps/my-frontend && npx tailwindcss init -p

Update our postcss config [apps/my-frontend/postcss.config.js]

const { join } = require('path');

module.exports = {
  plugins: {
    tailwindcss: {
      config: join(__dirname, 'tailwind.config.js'),
    },
    autoprefixer: {},
  },
};

Update styles.css to use tailwind [apps/my-frontend/pages/styles.css]

Note: We can delete rest of styles later. For now we keep until we update our pages.

@tailwind base;
@tailwind components;
@tailwind utilities;

Setup globally shared tailwind presets (i.e colour scheme) for use in multiple apps [./tailwind.workspace.preset.js]

We import typography package globally here as example, see more presets here

module.exports = {
  theme: {
    extend: {
      colors: {
        'my-white': '#ffffff',
        'my-grey': '#333333',
      },
    },
  },
  variants: {
    extend: {},
  },
  plugins: [require('@tailwindcss/typography')],
};

Update tailwind config in our frontend [my-frontend/tailwind.config.js]

const { join } = require('path');

// available since Nx v 12.5
const { createGlobPatternsForDependencies } = require('@nrwl/next/tailwind');

module.exports = {
  presets: [require('../../tailwind.workspace.preset.js')],
  purge: [
    join(__dirname, 'pages/**/*.{js,ts,jsx,tsx}'),
    ...createGlobPatternsForDependencies(__dirname),
  ],
  darkMode: 'media', // or 'media' or 'class'
  theme: {
    extend: {},
  },
  variants: {
    extend: {},
  },
  plugins: [],
};

Test our bundle sizes in the frontend. Consider routes for optimisation if necessary.

npx nx run my-frontend:export

Long manual setup guide here

Automatic Dark/Light

Setting up Authentication

NOTE: gql query createUser, does not encrypt password, its for admin use if anything. FYI. Auth not work when made that way.. use signupInput gql query instead

Create lib

npx nx g @nrwl/nest:resource -p my-backend --directory="app/resources" --type="graphql-code-first" --crud --name authentication

Test sign up graphiql playground

mutation {
  signup(signupInput: { email: "test@ysignup.com", password: "tytycftgc" }) {
    id
  }
}

Implementing auth guards and securing auth

Summary

Add libraries
Add jwt modules etc to .module files
Add validation logic
Add guards
Add local strategy
Test query to confirm its all working

Commits

Using passport -> npm i passport-jwt
Implementing our own jwt strategies
Create our set and verify auth guards logic
Add guard decorators to routes
make cookies secure
add CSRF protection to cookies
read best practises: https://www.rfc-editor.org/rfc/rfc8725.html

mutation {
  login(loginInput: { email: "test@ysignup.com", password: "tytycftgc" }) {
    id
  }
}

Now we will verify our jwt here at jwt.io

Create some pages for /login and /signup

npx nx g @nrwl/next:page --project=my-frontend --style=css --name=login
npx nx g @nrwl/next:page --project=my-frontend --style=css --name=signup

Testing our login through the dev tools response section

Implement cookies ....

Confirming cookies received through dev tools application section

Setup Serverside rendering (SSR) for graphql backend requests

Let's start by checking the dev tools under Network -> Fetch/XHR
Here we can see the client side requests our app makes
Notice that the graphql server is requested from the client side [fetch] , this is going to slow our page loads!

Let's get to work implementing it...

create my-server-api to handle SSR -> example of my-server-api.ts
add get serverside props to /users -> example commit implementing SSR on frontend
confirm its working in dev tools as above in network tab. No more 200 request to Graphql

Here we can confirm using the chrome dev tools that the graphql server is no longer fetched from the client side.

Setup linting and enforce code style with eslint

See commit diff here

We are going to use a eslint rules library

the reason being is that we wish to start with sane defaults, enforce modern and up to date code styles

Later on we can configure on a rule by rule basis as we desire

Install eslint deps

npm i --save-dev eslint eslint-plugin-unicorn eslint-plugin-prettier

Configure eslint with our new plugins and rules [./.eslintrc.json]

{
  "root": true,
  "ignorePatterns": ["**/*"],
  "plugins": ["@nrwl/nx", "unicorn", "prettier"],
  "overrides": [
    {
      "extends": ["plugin:unicorn/recommended", "plugin:prettier/recommended"],
      "files": ["*.ts", "*.tsx", "*.js", "*.jsx"],
      "rules": {
        "prettier/prettier": ["error"],
        "unicorn/prevent-abbreviations": "warn",
        "unicorn/no-null": "off",
        "unicorn/prefer-module": ["warn"],
        "unicorn/no-abusive-eslint-disable": ["warn"],
        "@nrwl/nx/enforce-module-boundaries": [
          "error",
          {
        ...rest-of-code...

Configure prettier with our new rules [./prettierrc]

Let's start by familisarising ourselves with available options here

{
  "semi": true,
  "trailingComma": "es5",
  "singleQuote": true,
  "bracketSpacing": true,
  "printWidth": 100
}

Run linters and formatters to test our new rules

npx nx format:write --all
npx nx run-many --target=lint --all

Setup application logging and analytics services

TODO

Setup Workspace Dependency Isolation

Defining boundaries with nx

Start by revieiwng the docs here

Let's check out our current dependency graph in a web browser using this command [http://127.0.0.1:4211/?]

npx nx graph

We can see here our dependency graphs are nicely laid out with our backend and frontend decoupled

Now let's try inheriting a library from our backend into our frontend to see how our dependency graph changes [my-frontend/pages/index.tsx]

import {
  CreateOneUserArgs,
  FindUniqueUserArgs,
  UpdateOneUserArgs,
  User,
} from '@my-full-stack-app/my-backend/generated/db-types';
type test = CreateOneUserArgs;

As we can see, we now have an extra path in our dependency graph, coupling our frontend and backend

We're now going to modify the snippet for our project as so and paste it into our config [./.eslintrc.json]

This will tell eslint to emit errors when we break the constraints we have defined. We will tell eslint that the backend and frontend aren't allowed in each others scope

"rules": {
"@nrwl/nx/enforce-module-boundaries": [
    "error",
    {
    "allow": [],
    "depConstraints": [
        {
        "sourceTag": "scope:shared",
        "onlyDependOnLibsWithTags": ["scope:shared"]
        },
        {
        "sourceTag": "scope:my-frontend",
        "onlyDependOnLibsWithTags": ["scope:shared", "scope:my-frontend", "scope:my-client"]
        },
        {
        "sourceTag": "scope:my-backend",
        "onlyDependOnLibsWithTags": ["scope:shared", "scope:my-backend"]
        },
        {
        "sourceTag": "scope:my-client",
        "onlyDependOnLibsWithTags": ["scope:shared", "scope:my-client"]
        }
    ]
    }
]
}

Run the linter to see if our boundaries are applied correctly, we should see an error

#Lint the frontend scope

npx nx lint my-frontend

#We should receive the response from the linter containing the below error

/Users/admin/Git_Downloads/monorepo-full-stack-web-app/nx-monorepo-full-stack-app/apps/my-frontend/pages/index.tsx
  4:1   error    A project tagged with "scope:my-frontend" can only depend on libs tagged with "scope:shared", "scope:my-frontend"  @nrwl/nx/enforce-module-boundaries

Let's delete the code we added earlier so that the frontend no longer inherits a library in the backend scope

Run the linter again and the error shown above should go away, there may still be some warnings, but we can fix those later

Our dependency graph should now look that same as it did earlier, perfect! We've now isolated our frontend from our backend successfully

npx nx lint my-frontend

Try lint the rest of your application, and get familiar with some of the other features of nx boundaries

#Lint all at once
npx nx run-many --target=lint --all
#Lint only changed files
npx nx affected --target=lint --all

NOTE If you are getting this error linting your app

error  A project without tags matching at least one constraint cannot depend on any libraries  @nrwl/nx/enforce-module-boundaries

Check that you have defined the scope tags properly in each library in your app, like so [./project.json]

Setting up CICD with Github Actions

Adding secrets to our GitHub repository for use in our actions

Head to the repository settings and configure your secrets as seen in the example below.

We will use a JWT_SECRET env var in our tests, so here we are setting it up.

Creating the GitHub action

Create a new .yaml file in ./.github/workflows/

Here we will create a CI.yaml as shown below

Things to make note of:

The secrets we are injecting into the CI using Github action secrets
We have configured the CI to continue on lint errors for now instead of exiting

name: CI
on:
  push:
    branches:
      - main
  pull_request:

jobs:
  main:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - uses: nrwl/nx-set-shas@v3
      - run: npm ci

      - run: npx nx workspace-lint
      - run: npx nx format:check
      - run: npx nx affected --target=lint --parallel=3
        continue-on-error: true
      - run: npx nx affected --target=test --parallel=3 --ci --code-coverage
        env:
          JWT_SECRET: ${{ secrets.JWT_SECRET }}
      - run: npx nx affected --target=build --parallel=3

Checking our CI runs, and NX cloud runs cache feature with parallelisation

If all is well, we should have a successful run

But do take note, 0 packages were actually tested! Why? The NX cache noticed no code was changed since last commit.

So with that said, lets add some code to a package, and see if the CI does run on that package.

Lets add a console.log('Index page'); to the index.tsx of our frontend and try it out

Success!! We can see our frontend was tested only, not the other unchanged packages in our NX workspace

Enabling NX Cloud runs github integration

Ensure @nrwl/nx-cloud is in package.json

Then run nx g @nrwl/nx-cloud:init

And follow the instructions, once setup, you should see NX bot in your Pull Requests make a comment with the status of the runs/builds etc as shown below

...time to fix up those lint warnings 😉

Benchmarking our API performance

Let's start with a very simple benchmark, to set a baseline, pulling our our GraphQL playground route

You can run this command directly on your CLI or add it to justfile and run it with just benchmark-backend

NOTE: Ensure the backend is running before benchmarking it

benchmark-backend:
    npx autocannon local -c 100 -d 5 -p 10 http://localhost:3333/graphql

Success! Our API is serving up our GraphQL playground frontend at ~50KTPS. That is over 3x faster than ExpressJS maximum throughput!!

Setting up code formatting to ignore auto-generated code

Create an .eslintignore
List the files and folders to ignore i.e
Add files here to ignore them from prettier formatting *.gql.gen.ts
