The problem is that Rust Jungle doesn't offer a built-in functionality so search its content.
The best thing at the moment is to open the stages overview and press ctrl + f.
There is also the consideration to add a search bar (#3). Maybe both features could live next to each other.

Describe the solution you'd like
You can define tags with the lesson component which can also be used for meta keywords (#17)

Describe alternatives you've considered
the mentioned search bar could make a tags system obsolete, since having a full-text search over the content is more powerful

Lately I've added Spectre to have a basic grid system and here and there some UI polish.
In general I want to avoid have unnecessary dependencies and therefore we could review Spectre and decide if it's really needed or if there is a better alternative (micro framework or writing the css code in shared.css).

Add an option to continue your option.
This is now prepared. The lesson component will save:

• title
• url
• date

the next time a user will open a non-lesson page, there should be a pop-up / notification if he / she wants to continue the lesson.
https://sweetalert2.github.io/ could be a possible package to use that.

This message should just come 1 time and then it should be deleted from the local storage and this popup should only come after a certain amount of time have passed.

If you open a lesson and want to jump to other lessons from that stage or to get an overview, you have to open the regular stages page.

Describe the solution you'd like
There could be a link in the lesson component to jumping to the specific stage anchor on the stages page.

Describe alternatives you've considered
As an alternative we could add a pop-up to show all lessons from the current stage, additionally to the next / previous navigation.

The website is already prepared for PWA. There's just a service worker missing to get the "install" button on browsers.

Currently there is just 1x keywords and description set in the app.html, which isn't very good for SEO.

Describe the solution you'd like
The solution depends on Svelte. It's probably something in the direction of named slots.

You should be able to navigate through the lessons with the arrow keys:

• left or up = previous lesson
• right or down = next lesson

Motivation

Since Rust compiler messages are very informative and they will help you to actually fix your code very often, there should be a lesson to highlight those compiler messages.
The end of stage 1 is probably a good place to explain that.

Reference to an existing lesson

the stage about text is probably a good place for it.

Motivation

Regular Expressions are a basic use case among programming languages.
Rust itself provides a package for it:

• https://github.com/rust-lang/regex
• https://docs.rs/regex/1.5.4/regex/

Currently there is just a previous and next navigation, but you don't know where exactly you are in the stage.

Describe the solution you'd like
There could be a simple "stage progress" information like:

< Previous        9 / 14        Next >

Describe alternatives you've considered
An alternative would be a restructuring of the page to always show the menu, like Rust does with mdBook.

Reference to an existing lesson

Should be a part of stage 2.

Motivation

In stage 2 there should be a lesson which explains Cargo.toml in details and shows which possibilities it offers.
It should also explain shortly why there is a Cargo.lock file.

Reference to an existing lesson

for Stage 7: Text

Motivation

to help with basic use cases.

Motivation

Rust editions are an important part for productive systems as it provides stability.
Therefore it should be a lesson about it, explaining it and show how to change it.
Stage 10 is probably the right place, since it's not important during the learning process.

Currently the stage overview component consists of manual entries which has several disadvantages.
It should read the stage folders (numerical folders) and build it dynamically.

Check links etc. so the website will work with multiple languages.
For example the menu is currently hard-coded with en.

Having a search bar would enable learners to easily find specific lessons.

This could be done together with #22, #23 and other topics in a new stage 11 (advanced Rust or something like that)
