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 🙏

SMTP mock server

Provides a mock SMTP server that can be used to verify and look at e-mails in end-to-end test. It provides a JSON API to await received e-mails.

Running

$ npx @anton-johansson/smtp-mock-server

Options

| Switch | Description | | -------------------- | --------------------------------------------------------- | | --smtp-port <port> | The port to serve the SMTP server on. Defaults to 3025. | | --api-port <port> | The port to serve the API on. Defaults to 3080. |

Example setup

package.json:

{
  "scripts": {
    "start": "node dist/index.js",
    "test:e2e": "npx playwright test",
    "test:e2e-ci": "start-test start 3000 'npx @anton-johansson/smtp-mock-server' 3080 test:e2e"
  },
  "devDependencies": {
    "start-server-and-test": "2.0.0"
  }
}

Then simply run npm run test:e2e-ci on your continuous integration server. It will fire up your server, the SMTP mock server, run the tests and then shut down the servers again.

API

Await e-mail

$ curl http://localhost:3080/await-email?subject=Hello

Parameters

| Query parameter key | Description | | ------------------- | ---------------------------------------------------------------------------------------- | | subject | Optional subject to filter by when awaiting e-mail. | | timeout | The number of milliseconds to wait for the e-mail. Defaults to 5000. | | remove | Whether or not to remove the email from the list after receiving it. Defaults to true. |

Clear e-mails

This one is not really useful during the actual end-to-end tests, but it can be useful to clear the e-mails before starting the tests when running tests locally.

$ curl -XPOST http://localhost:3080/clear-emails
