lighthouse VS IPC144

Google Core Vitals now represent the most important metrics to focus on when it comes to technical SEO. Google Core Vitals are a set of standardized metrics that Google uses to evaluate the user experience offered by a web page and assign it a technical SEO grade. Several tools exist to measure and report technical SEO performance, but the most reliable is Google Lighthouse.

- referred to https://github.com/GoogleChrome/lighthouse/issues/6512 but didnt see network.disable error - added staticdistdir as per https://github.com/GoogleChrome/lighthouse-ci/blob/main/docs/configuration.md,

There has been discussion about adding a visual indicator to make the mode more obvious, but it has not made it into Chrome devtools!

I haven't tried it, but you might be able to control throttling by using lighthouse to get performance data: https://github.com/GoogleChrome/lighthouse/blob/main/docs/throttling.md

When we implemented the MVP of the fintech app, we had a quite complicated form. At that time, I was still young and inexperienced. And eventually, we realized that our project was slowing down. We had to spend additional hours figuring out the reason. We had many unnecessary re-renders because we ignored basic rules related to props in React. I wanted to do everything possible to avoid such situations in the future. So, I added to the project linters like this and an additional starting configuration to package.json to run why-did-you-render. In short, this plugin issues a warning if something is re-rendered unnecessarily and suggests how to avoid it. Also, we included running Lighthouse in headless mode. Some people say that premature optimizations are bad, but for me, it's a principle: do it right from the start.

You can run a Lighthouse audit in two ways: either on the command line or in a browser. If you want to run audits on the command line, you will first need to install the Lighthouse command:

i wanted to run the lighthouse(lh) docker container on multiple EC2 instances in different regions. I'm thinking of triggering the EC2 instance with the lambda function once the lh container has audited the URL the results will be sent "SUB rest API" which will further update the UI

There's a link to what they mean by mobile network there (https://github.com/GoogleChrome/lighthouse/blob/main/docs/throttling.md) and it says:

Here's the non-psuedo code equivalent that can leverage CompressionStream rather than using a browserified-gzip-library: https://github.com/GoogleChrome/lighthouse/blob/437eb4d757c5...

We use it in Lighthouse for the exact same purpose, a URL #hash full of state. We found that modern browsers support 10mb of data in the hash. https://github.com/GoogleChrome/lighthouse/pull/12509#discus...

Lighthouse: This is an open-source tool developed by Google that allows you to audit the performance of your website. You can use Lighthouse to get a detailed report on your website's Core Web Vitals, as well as other performance metrics. You can run Lighthouse in Chrome DevTools or as a command-line tool.

Reviewing two PRs from a classmate is one of the duties for this project. The PRs, as well as my reviews, are available here and here. Both of the PRs I reviewed were really well-written and detailed, with very few mistakes. It was interesting to observe how different people approached certain changes, such as adding a svg file.

For this assignment we had to contribute to a Seneca repository. I chose the IPC144 repo.

Issue: https://github.com/Seneca-ICTOER/IPC144/issues/64 I worked on the standardized front matter across all markdown pages. This open-source project is the C language course notes of my major program.

And the reason why the web-only artifacts is still appear on the PDF page is because the --excludeSelectors option is not implemented enough. I have to add .clean-btn to the --excludeSelectors, the purpose of this is not to include the "On the page" artifact in side the PDF page. This is the final source code I have implement for this improvement and my pull request

I think I was able to do a good job meeting my goals I gave myself in my planning phase of this release. I was able to finish the issues well on schedule while balancing my other courses like I hoped and I was able to properly audit and fix both issues #122 and #123 without needing too many changes after review. What I learned from those two issues is the importance to read and checkout other issues/pull requests, especially for smaller repos. As I was told in the review for both my issues, I learned that the project recently made changes with how we would format the frontmatter. In PR #142 we no longer use the slug for pages due to inconsistency with links and we also need to include a description to follow the standardized Frontmatter as updated in PR #143.

The first issue I was working on IPC144 Course Note is about improving the usability of the PDF file generated from the website. All contents are generated inside the PDF, however, we want to get this better since some of the pictures are not showing properly, and also the web-only artifacts are still on the PDF, which we do not want it when we use the "PDF" version. convert-to-pdf.sh file would be modified a bit to accomplish this.

Issue #113

PR

As for this pull request, the code review went much more smoothly, with me having to only make minor changes to ensure that it would not cause any errors when built.
