Create logic that redirects old challenge URLs to new beta URLs

For example, /challenges/check-for-palindromes should redirect to /en/challenges/javascript-algorithms-and-data-structures-projects/palindrome-checker

Here is a full list of current challenges on production.

In situations where these lack a beta equivalent, they can just redirect to /map

Note that all existing projects still exist on beta, though some of them have been moved to the interview-prep section.

Hi @joker314 thanks for your work on this so far! To answer your questions individually:

@QuincyLarson out of interest, how did you generate your list?

I used https://www.freecodecamp.org/sitemap.xml and filtered out the challenge URLs.

beta doesn’t have a /videos endpoint for video lessons

Yes - we can ignore those video links - we don’t need to redirect them.

beta doesn’t have certificates for projects other than the JS one

I’m not sure what you mean here. The projects themselves have beta equivalents (though some of them may be in the Interview Prep > Takehome Projects section.

Do we map these jQuery links to their JavaScript equivalents, or do we just send these users to the map because they probably wanted to learn jQuery? (I’ve done the former, but this can be changed)

Please use your best judgement on these. In this case, I think you’re correct in linking to the JavaScript equivalents.

Do we send the user to the first project in that section (what I’m doing at the moment, but can be changed), or, do we send the user to the map [is there a way to highlight a particular section in the map; a bit like the suggestion in #16902]

We don’t yet have a way to link directly to an entire section of the map. https://github.com/freeCodeCamp/freeCodeCamp/issues/11060

is the introduction for the API and Microservice Projects section in freeCodeCamp. But that’s the problem, it’s an entire section, not a challenge, and it lacks an introduction like the old version does.

Both of these sections walk through how to use Glitch.com to complete the projects:

• https://beta.freecodecamp.org/en/challenges/managing-packages-with-npm/introduction-to-the-managing-packages-with-npm-challenges
• https://beta.freecodecamp.org/en/challenges/information-security-with-helmetjs/introduction-to-information-security-with-helmetjs-challenges

I propose we just forward this link to one of these links for now.
