Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Define Matcher for jest in apigateway-lambda-inversify-integration library.

Usage

setting jest

In order for Jest to recognize it, you need to configure the following settings in Jest.

setupFilesAfterEnv: ['apigateway-lambda-inversify-integration']

Typescript

Add import 'apigateway-lambda-inversify-integration-jest'; to global.d.ts.

unit test

Several Matchers have been implemented for unit testing of HttpMethodController.

・ matcher that evaluates whether the specified HTTP Method is implemented.

For example, if you have a class called Test1Controller that extends HttpMethodController, and you want to evaluate whether a GET method has been defined, you can evaluate it as follows

  it('Test', async () => {
    const controller = new Test1Controller();
    expect(controller).toBeMethodDefied('GET');
  });

・ Matcher that evaluates whether or not the authentication is correctly set for the specified HTTP Method.

For methods that require authentication

  it('Test', async () => {
    const controller = new Test1Controller();
    expect(controller).toBeMethodAuthentication('GET');
  });

For methods that do not require authentication

  it('Test', async () => {
    const controller = new Test1Controller();
    expect(controller).not.toBeMethodAuthentication('GET');
  });

・ Matcher that evaluates whether or not the specified function is defined in the specified HTTP method.

  it('Test', async () => {
    const controller = new Test1Controller();
    expect(controller).toBeMethodFunction('GET', 'get');
  });

・ matcher that evaluates if the validation is set correctly for the specified HTTP Method.

When the ITest type is defined in the Body parameter of the POST method in Test1Controller, validation can be evaluated for each key of the ITest type.

 it('Test', async () => {
    const controller = new Test1Controller();
    const validation: Validators = { type: 'string', required: true };
    expect(controller).toBeMethodValidation<ITest>('POST', 'bodyValidator', 'key', validation);
  });
class Test1Controller extends HttpMethodController<any> {
  public constructor() {
    super();
    this.setMethod('POST', {
      func: this.test,
      isAuthentication: false,
      validation: {
        bodyValidator: {
          key: {
            type: 'string',
            required: true
          },
          num: {
            type: 'number',
            required: true,
            integer: true,
            lessThan: 1
          }
        }
      }
    });
  }

  private async test(event: CallFunctionEventParameter<any, ITest, never, never, any>): Promise<APIGatewayProxyResult> {
    return {
      body: JSON.stringify({ ...event.userInfo, ...{ uri: '/test' } }),
      statusCode: 200
    };
  }
}

interface ITest {
  key: string;
  num: number;
}
