# Node - Koa - Typescript Project



[![NPM version](https://img.shields.io/npm/v/node-typescript-koa-rest.svg)](https://www.npmjs.com/package/node-typescript-koa-rest)

[![Dependency Status](https://david-dm.org/javieraviles/node-typescript-koa-rest.svg)](https://david-dm.org/javieraviles/node-typescript-koa-rest)



The main purpose of this repository is to build a good project setup and workflow for writing a Node api rest in TypeScript using KOA and an SQL DB.



Koa is a new web framework designed by the team behind Express, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs. Through leveraging generators Koa allows you to ditch callbacks and greatly increase error-handling. Koa does not bundle any middleware within core, and provides an elegant suite of methods that make writing servers fast and enjoyable.



Through Github Actions CI, this boilerplate is deployed [here](https://node-typescript-koa-rest.herokuapp.com/)! You can try to make requests to the different defined endpoints and see how it works. The following Authorization header will have to be set (already signed with the boilerplate's secret) to pass the JWT middleware:



HEADER (DEMO)

```

Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjEiLCJuYW1lIjoiSmF2aWVyIEF2aWxlcyIsImVtYWlsIjoiYXZpbGVzbG9wZXouamF2aWVyQGdtYWlsLmNvbSJ9.7oxEVGy4VEtaDQyLiuoDvzdO0AyrNrJ_s9NU3vko5-k

```



AVAILABLE ENDPOINTS DEMO [SWAGGER DOCS DEMO](https://node-typescript-koa-rest.herokuapp.com/swagger-html)



When running the project locally with `watch-server`, being `.env` file config the very same as `.example.env` file, the swagger docs will be deployed at: `http:localhost:3000/swagger-html`, and the bearer token for authorization should be as follows:



HEADER (LOCALHOST BASED ON DEFAULT SECRET KEY 'your-secret-whatever')

## Docker (optional)

A docker-compose file has been added to the project with a postgreSQL (already setting user, pass and dbname as the ORM config is expecting) and an ADMINER image (easy web db client).



It is as easy as go to the project folder and execute the command 'docker-compose up' once you have Docker installed, and both the postgreSQL server and the Adminer client will be running in ports 5432 and 8080 respectively with all the config you need to start playing around. 



If you use Docker natively, the host for the server which you will need to include in the ORM configuration file will be localhost, but if you were to run Docker in older Windows versions, you will be using Boot2Docker and probably your virtual machine will use your ip 192.168.99.100 as network adapter (if not, command `docker-machine ip` will tell you). This mean your database host will be the aforementioned ip and in case you want to access the web db client you will also need to go to http://192.168.99.100/8080



## Setting up the Database - ORM

This API is prepared to work with an SQL database, using [TypeORM](https://github.com/typeorm/typeorm). In this case we are using postgreSQL, and that is why in the package.json 'pg' has been included. If you where to use a different SQL database remember to install the correspondent driver.



The ORM configuration and connection to the database can be specified in the file 'ormconfig.json'. Here is directly in the connection to the database in 'server.ts' file because a environment variable containing databaseUrl is being used to set the connection data. This is prepared for Heroku, which provides a postgres-string-connection as env variable. In local is being mocked with the docker local postgres as can be seen in ".example.env"



It is importante to notice that, when serving the project directly with *.ts files using ts-node,the configuration for the ORM should specify the *.ts files path, but once the project is built (transpiled) and run as plain js, it will be needed to change it accordingly to find the built js files:



```

"entities": [

      "dist/entity/**/*.js"

   ],

   "migrations": [

      "dist/migration/**/*.js"

   ],

   "subscribers": [

      "dist/subscriber/**/*.js"

   ]

```



**NOTE: this is now automatically handled by the NODE_ENV variable too. 



Notice that if NODE_ENV is set to development, the ORM config won't be using SSL to connect to the DB. Otherwise it will.



And because Heroku uses self-signed certificates, this bit has been added, **please take it out if connecting to a local DB without SSL**.



```

createConnection({

    ...

    extra: {

        ssl: {

            rejectUnauthorized: false // Heroku uses self signed certificates

        }

    }

 })

```



You can find an implemented **CRUD of the entity user** in the correspondent controller controller/user.ts and its routes in routes.ts file.



## Entities validation

This project uses the library class-validator, a decorator-based entity validation, which is used directly in the entities files as follows:

```

export class User {

    @Length(10, 100) // length of string email must be between 10 and 100 characters

    @IsEmail() // the string must comply with an standard email format

    @IsNotEmpty() // the string can't be empty

    email: string;

}

```

Once the decorators have been set in the entity, you can validate from anywhere as follows:

```

const user = new User();

user.email = "avileslopez.javier@gmail"; // should not pass, needs the ending .com to be a valid email



validate(user).then(errors => { // errors is an array of validation errors

    if (errors.length > 0) {

        console.log("validation failed. errors: ", errors); // code will get here, printing an "IsEmail" error

    } else {

        console.log("validation succeed");

    }

});

```



For further documentation regarding validations see [class-validator docs](https://github.com/typestack/class-validator).



## Environment variables

Create a .env file (or just rename the .example.env) containing all the env variables you want to set, dotenv library will take care of setting them. This project is using three variables at the moment:



 * PORT -> port where the server will be started on, Heroku will set this env variable automatically

 * NODE_ENV -> environment, development value will set the logger as debug level, also important for CI. In addition will determine if the ORM connects to the DB through SSL or not.

 * JWT_SECRET -> secret value, JWT tokens should be signed with this value

 * DATABASE_URL -> DB connection data in connection-string format.



## Getting TypeScript

TypeScript itself is simple to add to any project with `npm`.

```

npm install -D typescript

```

If you're using VS Code then you're good to go!

VS Code will detect and use the TypeScript version you have installed in your `node_modules` folder. 

For other editors, make sure you have the corresponding [TypeScript plugin](http://www.typescriptlang.org/index.html#download-links). 



## Project Structure

The most obvious difference in a TypeScript + Node project is the folder structure.

TypeScript (`.ts`) files live in your `src` folder and after compilation are output as JavaScript (`.js`) in the `dist` folder.



The full folder structure of this app is explained below:



> **Note!** Make sure you have already built the app using `npm run build`

## Configuring TypeScript compilation

TypeScript uses the file `tsconfig.json` to adjust project compile options.

Let's dissect this project's `tsconfig.json`, starting with the `compilerOptions` which details how your project is compiled. 



```json

    "compilerOptions": {

        "module": "commonjs",

        "target": "es2017",

        "lib": ["es6"],

        "noImplicitAny": true,

        "strictPropertyInitialization": false,

        "moduleResolution": "node",

        "sourceMap": true,

        "outDir": "dist",

        "baseUrl": ".",

        "experimentalDecorators": true,

        "emitDecoratorMetadata": true,  

        }

    },

```



| `compilerOptions` | Description |

| --------------------------------------- | ------------------------------------------------------------------------------------------------------ |

| `"module": "commonjs"`                  | The **output** module type (in your `.js` files). Node uses commonjs, so that is what we use           |

| `"target": "es2017"`                    | The output language level. Node supports ES2017, so we can target that here                            |

| `"lib": ["es6"]`                        | Needed for TypeORM.                                                                                    |

| `"noImplicitAny": true`                 | Enables a stricter setting which throws errors when something has a default `any` value                |

| `"moduleResolution": "node"`            | TypeScript attempts to mimic Node's module resolution strategy. Read more [here](https://www.typescriptlang.org/docs/handbook/module-resolution.html#node)              |

| `"sourceMap": true`                     | We want source maps to be output along side our JavaScript.                                            |

| `"outDir": "dist"`                      | Location to output `.js` files after compilation                                                       |

| `"baseUrl": "."`                        | Part of configuring module resolution.                                                                 |

| `paths: {...}`                          | Part of configuring module resolution.                                                                 |

| `"experimentalDecorators": true`        | Needed for TypeORM. Allows use of @Decorators                                                          |

| `"emitDecoratorMetadata": true`         | Needed for TypeORM. Allows use of @Decorators                                                          |



The rest of the file define the TypeScript project context.

The project context is basically a set of options that determine which files are compiled when the compiler is invoked with a specific `tsconfig.json`.

In this case, we use the following to define our project context: 

```json

    "include": [

        "src/**/*"

    ]

```

`include` takes an array of glob patterns of files to include in the compilation.

This project is fairly simple and all of our .ts files are under the `src` folder.

For more complex setups, you can include an `exclude` array of glob patterns that removes specific files from the set defined with `include`.

There is also a `files` option which takes an array of individual file names which overrides both `include` and `exclude`.



## Running the build

All the different build steps are orchestrated via [npm scripts](https://docs.npmjs.com/misc/scripts).

Npm scripts basically allow us to call (and chain) terminal commands via npm.

This is nice because most JavaScript tools have easy to use command line utilities allowing us to not need grunt or gulp to manage our builds.

If you open `package.json`, you will see a `scripts` section with all the different scripts you can call.

To call a script, simply run `npm run ` from the command line.

You'll notice that npm scripts can call each other which makes it easy to compose complex builds out of simple individual build scripts.

Below is a list of all the scripts this template has available:



| Npm Script | Description |

| ------------------------- | ------------------------------------------------------------------------------------------------- |

| `start`                   | Does the same as 'npm run serve'. Can be invoked with `npm start`                                 |

| `build`                   | Full build. Runs ALL build tasks (`build-ts`, `lint`, `copy-static-assets`)                       |

| `serve`                   | Runs node on `dist/server/server.js` which is the apps entry point                                |

| `watch-server`            | Nodemon, process restarts if crashes. Continuously watches `.ts` files and re-compiles to `.js`   |

| `build-ts`                | Compiles all source `.ts` files to `.js` files in the `dist` folder                               |

| `lint`                    | Runs ESLint check and fix on project files                                                        |

| `copy-static-assets`      | Calls script that copies JS libs, fonts, and images to dist directory                             |

| `test:integration:`  | Execute Postman integration tests collection using newman on any env (`local` or `heroku`)        |

| `test:load`               | Execute Locust load tests using a specific configuration                                          |



# CI: Github Actions

Using Github Actions a pipeline is deploying the application in Heroku and running tests against it, checking the application is healthy deployed. The pipeline can be found at `/.github/workflows/test.yml`. This performs the following:

 - Build the project

   - Install Node

   - Install dependencies

   - Build the project (transpile to JS)

   - Run unit tests

 - Deploy to Heroku

   - Install Docker cli

   - Build the application container

   - Install Heroku cli

   - Login into Heroku

   - Push Docker image to Heroku

   - Trigger release in Heroku

 - Run integration tests

   - Install Node

   - Install Newman

   - Run Postman collection using Newman against deployed app in Heroku

 - Run load tests

   - Install Python

   - Install Locust

   - Run Locust load tests against deployed app in Heroku 



# ESLint

Since TSLint is deprecated now, ESLint feels like the way to go as also supports typescript. 

ESLint is a static code analysis tool for identifying problematic patterns found in JavaScript/typescript code.



## ESLint rules

Like most linters, ESLint has a wide set of configurable rules as well as support for custom rule sets.

All rules are configured through `.eslintrc`.

In this project, we are using a fairly basic set of rules with no additional custom rules.



## Running ESLint

Like the rest of our build steps, we use npm scripts to invoke ESLint.

To run ESLint you can call the main build script or just the ESLint task.

```

npm run build   // runs full build including ESLint format check

npm run lint    // runs ESLint check + fix

```

Notice that ESLint is not a part of the main watch task.

It can be annoying for ESLint to clutter the output window while in the middle of writing a function, so I elected to only run it only during the full build.

If you are interested in seeing ESLint feedback as soon as possible, I strongly recommend the [ESLint extension in VS Code](https://github.com/Microsoft/vscode-eslint.git).



# Register cron jobs

[Cron](https://github.com/node-cron/node-cron) dependency has been added to the project together with types. A `cron.ts` file has been created where a cron job is created using a cron expression configured in `config.ts` file. 



```

import { CronJob } from 'cron';

import { config } from './config';



const cron = new CronJob(config.cronJobExpression, () => {

    console.log('Executing cron job once every hour');

});



export { cron };

```



From the `server.ts`, the cron job gets started:



```

import { cron } from './cron';

// Register cron job to do any action needed

cron.start();

```



# Integrations and load tests

Integrations tests are a Postman collection with assertions, which gets executed using Newman from the CI (Github Actions). It can be found at `/integrationtests/node-koa-typescript.postman_collection.json`; it can be opened in Postman and get modified very easily. Feel free to install Newman in your local environment and trigger `npm run test:integration:local` command which will use local environment file (instead of heroku dev one) to trigger your postman collection faster than using postman.



Load tests are a locust file with assertions, which gets executed from the CI (Github Actions). It can be found at `/loadtests/locustfile.py`; It is written in python and can be executed locally against any host once python and locust are installed on your dev machine.



**NOTE: at the end of load tests, an endpoint to remove all created test users is called.



# Logging

Winston is designed to be a simple and universal logging library with support for multiple transports.



A "logger" middleware passing a winstonInstance has been created. Current configuration of the logger can be found in the file "logger.ts". It will log 'error' level to an error.log file and 'debug' or 'info' level (depending on NODE_ENV environment variable, debug if == development) to the console.



```

// Logger middleware -> use winston as logger (logger.ts with config)

app.use(logger(winston));

```



# Authentication - Security

The idea is to keep the API as clean as possible, therefore the auth will be done from the client using an auth provider such as Auth0. The client making requests to the API should include the JWT in the Authorization header as "Authorization: Bearer ". HS256 will be used as the secret will be known by both your api and your client and will be used to sign the token, so make sure you keep it hidden.



As can be found in the server.ts file, a JWT middleware has been added, passing the secret from an environment variable. The middleware will validate that every request to the routes below, MUST include a valid JWT signed with the same secret. The middleware will set automatically the payload information in ctx.state.user.



```

// JWT middleware -> below this line, routes are only reached if JWT token is valid, secret as env variable

app.use(jwt({ secret: config.jwtSecret }));

```

Go to the website [https://jwt.io/](https://jwt.io/) to create JWT tokens for testing/debugging purposes. Select algorithm HS256 and include the generated token in the Authorization header to pass through the jwt middleware.



Custom 401 handling -> if you don't want to expose koa-jwt errors to users:

```

app.use(function(ctx, next){

  return next().catch((err) => {

    if (401 == err.status) {

      ctx.status = 401;

      ctx.body = 'Protected resource, use Authorization header to get access\n';

    } else {

      throw err;

    }

  });

});

```



If you want to authenticate from the API, and you fancy the idea of an auth provider like Auth0, have a look at [jsonwebtoken — JSON Web Token signing and verification](https://github.com/auth0/node-jsonwebtoken)



## CORS

This boilerplate uses @koa/cors, a simple CORS middleware for koa. If you are not sure what this is about, click [here](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS).



```

// Enable CORS with default options

app.use(cors());

```

Have a look at [Official @koa/cors docs](https://github.com/koajs/cors) in case you want to specify 'origin' or 'allowMethods' properties.



## Helmet

This boilerplate uses koa-helmet, a wrapper for helmet to work with koa. It provides important security headers to make your app more secure by default. 



Usage is the same as [helmet](https://github.com/helmetjs/helmet). Helmet offers 11 security middleware functions (clickjacking, DNS prefetching, Security Policy...), everything is set by default here.



```

// Enable helmet with default options

app.use(helmet());

```



Have a look at [Official koa-helmet docs](https://github.com/venables/koa-helmet) in case you want to customize which security middlewares are enabled.
