Hi, thanks so much for this tutorial!

When we refresh we loose the state. I think the community would be really grateful if you explain us how to save the state in account as it is a basic feature.

Thanks!

This defines a hard 128 size limit on the collection of string to be added,

So this will fail with custom program error: 0xa4 when you try to say update it with some long length string.
ex. Some new data how long can this go before breaking apart?

Maybe this example can be updated with better examples using concept of PDA's.
I'm working on coming up with a better example that solves this using PDA's. Will PR soon.

Hi,
i'm facing this error can you please help me?

i'm running test using anchor test

anchor.setProvider(anchor.Provider.env());
const program = anchor.workspace.Myepicproject;
const tx = await program.rpc.startStuffOff(); // error is here

Thanks for the great content! Minor edit: user must update the wallet keypair file under [provider] in Anchor.toml before running anchor test to their local keypair (it currently reads /Users/ndabit/...).

Hey there,

having troubles with the test on this, there's a variable that is assigned but is not declared anywhere in the file

https://github.com/dabit3/complete-guide-to-full-stack-solana-development/blob/main/example1/tests/example1.js
(line 24)

    _baseAccount = baseAccount;

but there is no declaration as shown on the test error

n,

Hi,

When trying to run the frontend from any of the examples. I get greeted with the following error:

Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

I googled around and apparently it can happen if different version of react are used. In my case I only see one version, eventhough it's regerenced more than once but it's getting 'deduped':

├─┬ @solana/[email protected]
│ ├─┬ [email protected]
│ │ └── [email protected] deduped
│ └── [email protected]
└─┬ @solana/[email protected]
  └── [email protected] deduped

To reproduce simply npm install in the app folder, then run npm start

Following this tutorial

I have followed all of the steps up to the point of building the counter code, including having a running localhost validator.

I have taken the output of solana address -k target/deploy/mysolanaapp-keypair.json

and input it in lib.rs and anchor.toml as instructed, and get the following after running anchor build and then anchor test:

mysolanaapp
