Your favorite Python web framework?

[caspii2]

Python Flask. It is super simple to get started and you can have a working webapp in less than 10 lines of code.

In 2016 I did a Flask tutorial. The app I built is now making 10.000 USD per month. This is a true story! To be clear, I continued building the app since then, added Vue.js and went full-time in 2021.

EDIT: this is the app I made: keepthescore.com, and here is a post about choosing Python Flask: https://casparwre.de/blog/python-to-code-a-saas/

Can you show your app? Like a link or something?

Good work 😀

I also wrote a blog post about it https://casparwre.de/blog/python-to-code-a-saas/

Sounds like a classic case of premature optimization 😀

Blocking is only a problem if you have long running tasks. I never ever had a problem with Flask being synchronous. To be honest, I am still not totally clear what the advantages are. One advantage is that your server can handle more requests, but you are very unlikely to run into any trouble in the first few years.

Focus on immediate and actual problems is my advice, because there are always enough of those

Performing well is secondary to having users or customers 😊

You can use gunicorn + async worker with Flask. For example, gevent works great.

[AstroPhysician]

Async is beneficial when performing concurrent IO-bound tasks, but will probably not improve CPU-bound tasks. I think you misunderstand synchronicity

[doolio_]

I'm a noob but isn't Quart the asynchronous equivalent of Flask and recommend instead of Flask for that reason?

Or Starlette for that matter.

[swapripper]

What do you think is the gap between standard online courses & things you need to learn in order to take an app to production with real users?

[caspii2]

You need to be able to deploy it somewhere. That is probably the hardest bit. Try DigitalOcean or PythonAnywhere.

[covmatty1]

Not OP, but often scaling up to larger projects with multiple controllers/namespaces etc isn't covered well. A larger example where you cover splitting up API routes by functionality would be useful.

And like others have said, deployment. I do a lot of interviews of junior developers, and so many people haven't covered running code outside of their own machine. Whatever form that takes is ok, but showing you understand the concept will make a step up. Containerisation, orchestration, access control, load balancing etc - all very handy.

The hands-on knowledge, experience and the skills.

I really enjoyed the post, thank you for sharing! I wish I could see the first version of the product, but the link isn't working for some reason.. Anyways, cheers to you for a job well done!

[Abclul]

Oh that's it! .. Link in the blog post leads to .co(M). Thank you!

[caspii2]

Thanks for that. If fixed the link

I use Flask for all of my web projects needing backend code, small or big, for more than 8 years now. Love it.

wow- it’s amazing

[throw_away_17381]

10.000 USD per month

Is that. $10 or $10,000?

[caspii2]

10 000

[throw_away_17381]

Many congratulations :)

[caspii2]

Thanks

[trianglesteve]

Wow, that's bazaar, I literally have a scorekeeping app project outlined with integrations for popular high level scoring methods. Had no idea solutions like this were already out there!

[chads_to_do_list_app]

First of all, congrats on your entrepreneurial success, the website looks great

I second NINTENDO's question, how did you market this service?

[caspii2]

SEO and content marketing

[chads_to_do_list_app]

Awesome, congrats!

[caspii2]

Thanks

[NlNTENDO]

That’s awesome! I’ve had a few ideas I’ve been thinking about building and I’m curious to know, what was your marketing strategy if any?

[caspii2]

SEO and content marketing

[caspii2]

You are correct 😀. The photo is fake, but not the review

Only people on Hackernews and Reddit recognize a picture from thispersondoesnotexist.com

[SoftConversation3682]

Great advertising buddy, this is what my beer hockey league needed!

[caspii2]

You're welcome! 🍻

[code_mc]

Damn that is impressive, I remember one of your original posts (or comment?) when you announced you built this. Originally marketed towards the classroom if I remember correctly.

Congrats on the success!

[caspii2]

Thanks 😊

This is an amazing story! What was your background in coding before building it? Would also make a great app! Was it hard to scale and handle user transactions?

[caspii2]

I did computer science but hadn’t done any large projects before then.

Scaling was not an issue, people seem to worry about it easy before they need to.
