Clean up any issues found.

Page Speed
- Browser caching issues

The problem is caused by

<script src="https://apis.google.com/js/platform.js?onload=onLoadCallback" async defer></script>

I cannot remove the code and I cannot modify and so there is nothing I can.

Page Speed
- HTML not minimized

Changed deploy-apps, added

#
# minify index.html
#
cp dist/index.html dist/index.work
html-minifier dist/index.work --remove-comments --output dist/index.html

Fixes the issue.

Page Speed
- CSS not minified

Problem is main.bundle.css which is minified but has a second line for source mapping. Remove the second line and the issue is resolved.

Fix webpack.config.js

const PRODUCTION_MODE = process.env.NODE_ENV === 'production';

devtool: PRODUCTION_MODE ? 'source-map' : 'inline-source-map',

Created new problems

Render blocking CSS and/or JS
Visible content not prioritized

Decided to use

devtool: 'inline-source-map'

for development and production.

Accessibility
- Language not declared ideally

Fix index.hbs

<html lang="en">

Accessibility
- No skip to main content link.

General issue, will require a separate project.

For detailed description of how to fix, see Skip to main content

Decided to leave this for now.

Varvy Speed Tool

Enter each URL and test.

CSS delivery
- Too many external CSS files
- CSS not minimized

External CSS location

https://fonts.googleapis.com/css?family=Roboto:300,400,500,700

https://www.taskmuncher.com/main.bundle.css

https://fonts.googleapis.com/icon?family=Material+Icons

All 3 are needed. Nothing to be done.

Browser caching
- Browser caching not enabled for all resources
  - Not enabled for third party resources apis.google.com

Decided to leave this.

Performance

Caused by bundle.js which is 16.1Mb

Chrome developer tools, network tab, bundle.js

Response headers

content-encoding: gzip
cache-control: max-age=31536000
download size = 3.8MB
actual size = 15.4MB

Verified bundle.js has been made correctly by Webpack. bundle.js is 16.1MB on disk and is minified. bundle.js has license info non-minified, which appears to be a legal requirement.

Don't see anything I can do about this.

Progressive Web App

Page load is not fast enough on 3G.
- Your page loads too slowly and is not interactive within 10 seconds.
Does not respond with a 200 when offline
- If you're building a Progressive Web App, consider using a service worker so that your app can work offline
User will not be prompted to Install the Web App
- Failures: Site does not register a service worker.
  - Browsers can proactively prompt users to add your app to their home screen, which can lead to higher engagement.
Does not register a service worker
- The service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to home screen, and push notifications
Does not provide fallback content when JavaScript is not available
- The page body should render some content if its scripts are not available.

Accessibility

Background and foreground colors do not have a sufficient contrast ratio.

Decided to leave this for now.

Google Page Speed Insights

Google PageSpeed Insights

Leverage browser caching
- https://apis.google.com/js/platform.js?onload=onLoadCallback

Decided to leave it alone.

Minifying https://www.taskmuncher.com/main.bundle.css could save 156B (39% reduction) after compression.

Added this to deploy-apps

echo "Minify main.bundle.css"
cp dist/main.bundle.css dist/main.bundle.css.work
html-minifier dist/main.bundle.css.work --remove-comments --output dist/main.bundle.css

actually works, as in the error goes away. Seems like such a terrible idea I removed the botch and decided to leave this alone.

Missing form label.

Caused by

<input aria-invalid="false" aria-required="false" autocomplete="email" class="jss137 jss140 jss138" name="email" placeholder="Email Address" type="email" value="">

Code uses TextField. Fix with

InputProps={ {
	inputProps: {
		'aria-label': 'Email Address',
		'aria-required': 'true'
	}
} }
