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 🙏

Profiled Mock API

This is a server built on top of express which serves JSON and XML files based on file/folder configuration. The root directory of the response files can be separated by "profiles."

Getting Started

Step 1: Create mock server

One can create a new index.ts file and fill it with contents:

import { MockApiServer, GlobalLogger, LogLevel } from 'profiled-mock-api'

GlobalLogger.getInstance().logLevel = LogLevel.ALL

const mockServer: MockApiServer = new MockApiServer({
    initialActiveProfile: "default", // default: 'default'
    port: 3000, // default 3000
    profileDirectory: "responses"
})


mockServer.start()

Step 2: Create response files

With file structure:

node_modules
responses
    default
        ping.json
index.ts
package.json

we can create ping.json:

{
    "message": "pong"
}

responses is where the profile directories will be stored. responses/default is the root directory where responses of the "default" profile will be served from.

Step 3: Run the server:

ts-node index.ts

Step 4: Call the endpoint:

GET http://localhost:3000/ping

Specify method and response

Option 1: Simple files:

Directory Structure:

resources
    default
        ping.json
        some
            deep
                path
                    status.json

Calls:

  • GET http://localhost:3000/ping
  • POST http://localhost:3000/ping
  • http://localhost:3000/ping
  • GET http://localhost:3000/some/deep/path/status
  • POST http://localhost:3000/some/deep/path/status
  • http://localhost:3000/some/deep/path/status

Option 2: Complex Files with HTTP Method:

Directory Structure:

resources
    default
        ping.GET.json
        ping.POST.json
        some
            deep
                path
                    status.GET.json
                    status.PUT.json

Calls:

  • GET http://localhost:3000/ping
  • POST http://localhost:3000/ping
  • GET http://localhost:3000/some/deep/path/status
  • PUT http://localhost:3000/some/deep/path/status

Option 3: Complex Files with HTTP Method and response status:

Directory Structure:

resources
    default
        ping.GET.200.json
        ping.POST.500.json
        some
            deep
                path
                    status.GET.200.json
                    status.PUT.201.json
        health
            check.500.json

Calls:

  • GET http://localhost:3000/ping
  • POST http://localhost:3000/ping
  • GET http://localhost:3000/some/deep/path/status
  • PUT http://localhost:3000/some/deep/path/status

Option 4: Directories:

Directory Structure:

resources
    default
        ping
            GET.json
            POST.json
        health
            check
                GET.json
                POST.201.json
                PUT.500.json

Calls:

  • GET http://localhost:3000/ping
  • POST http://localhost:3000/ping
  • GET http://localhost:3000/health/check
  • POST http://localhost:3000/health/check
  • PUT http://localhost:3000/health/check

Profiles

Suppose we have a directory structure as follows:

resources
    test_case_happy_path
        ping
            GET.200.json
        health
            check
                GET.200.json
    test_case_evtang_broken
        ping
            GET.500.json
        health
            check
                GET.500.json

All Profiles:

Profiles can be seen at GET http://localhost:3000/profiles:

{
    "test_case_happy_path": {
        "responseFileBasePath": "responses\\test_case_happy_path"
    },
    "test_case_evtang_broken": {
        "responseFileBasePath": "responses\\test_case_evtang_broken"
    }
}

Active Profiles:

The active profile can be seen at GET http://localhost:3000/activeProfile:

{
    "activeProfile": "test_case_happy_path"
}

Changing Active Profile:

The active profile can be seen at POST http://localhost:3000/activeProfile: with body

{
    "newlyActiveProfile": "test_case_happy_path"
}

Response 200: {

}
