$ npm run migration:run

# db seeding with small database
$ npm run migration:seed

# update entities and migrate db
$ npm run database:initialize

Running Migration & Seeding (After release)

$ npm run migration:run

Running middleware

Run software which the app depends on for development

• mailhog (Web and API based SMTP testing)
• mysql

docker network create red-network
docker-compose up

Running the app

# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod

Running the app as scheduler

Rules

Create a new module

When you want to create a new module, the following command is preferred to run.

# create a new module
$ npm run generate:module <your_module_name>
CREATE /src/modules/<your_module_name>/<your_module_name>.module.ts (xx bytes)
UPDATE /src/modules/app.module.ts (xx bytes)

# create a controller in created module
$ npm run generate:controller <your_module_name>
CREATE /src/modules/<your_module_name>/<your_module_name>.controller.spec.ts (xx bytes)
CREATE /src/modules/<your_module_name>/<your_module_name>.controller.ts (xx bytes)
UPDATE /src/modules/<your_module_name>/<your_module_name>.module.ts (xx bytes)

# create a service in created module, if needed
$ npm run generate:service <your_module_name>
CREATE /src/modules/<your_module_name>/<your_module_name>.service.spec.ts (xx bytes)
CREATE /src/modules/<your_module_name>/<your_module_name>.service.ts (xx bytes)
UPDATE /src/modules/<your_module_name>/<your_module_name>.module.ts (xx bytes)

Unit test & Coverage

You have to write unit test codes in order to maintain code coverage and reduce runtime errors. Unit test code is required when you create a class such as service, controller or etc.

  it('should be defined', () => {

    it('token verification sould be failed', async () => {
      const token = '1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx1';
      await expect(service.verifyEmailToken(token)).rejects.toBeInstanceOf(
        DataNotFoundException,
      );
    });

    it('token verification sould be expired', async () => {
      const token = new EmailVerification({
        userId: 1,
        email: '[email protected]',
      });
      token.expiresAt = new Date();
      await repository.save(token);
      await expect(
        service.verifyEmailToken(token.verificationToken),
      ).rejects.toBeInstanceOf(EmailVerificationTokenExpiredException);
