Amazing work, NIce UI too, would be great if people can preview the project before deploying to IC

Hi @fxgst

I’m planning a new course focused on application development skills for the Internet Computer and wanted to ask if it would be possible to include the ICP Ninja IDE as part of the course. I believe it could be a valuable tool for the participants.

Looking forward to your thoughts!

Hi @rbole,

Absolutely, that’s certainly possible! ICP Ninja is a great place to start developing first canisters on ICP. Note that for more advanced features, you might have to download the project from ninja and continue locally. If you want to, you can share what you want to do in the course and I can let you know if the things can be done in ICP Ninja

Hi @fxgst

Why can’t someone edit the Cargo.toml file in ICP Ninja? What if you’d like to add some extra crates to use in you canister :thinking: ?

12

Asking AI in Ninja :slight_smile: returns:

If you need to modify these restricted files, the documentation suggests downloading the project and continuing development with dfx :
“To continue developing an ICP Ninja project or to add features to the project that exceed the IDE’s current limitations, you can download the project’s files and use dfx . From the ICP Ninja IDE, select ‘Download files’ to download a .zip folder containing the project’s code files.” ICP Ninja documentation

Pretty awesome.

Oh damn

Is there a way someone can re-upload the project back to ICP Ninja?

14

Not that I am aware of, there is just the create custom project template. Were you signed in ? It should keep track.

BTW this is the working link ICP Ninja | Internet Computer , the one the AI gives as reference is gone.

Can confirm, the same.
Any particular reason why you don’t “play” locally ? Specially since I see you favor rust.

No, I do most of my developments locally. But I was training some new devs for an AI hackthon we’re doing, then they gave me the complaint that it wasn’t working.

Yes, I am a big advocate for rust.

The deployments are working again. We’ll look into this to make it more robust.

With the current build setup we can’t safely let people use arbitrary crates. We’re working on it
