Hello everyone,
Problem Statement: In my application, I need to dynamically create new canisters based on certain conditions. To achieve this, I’m using the ic.create_canister
and ic.install_code
functions provided by the DFINITY Internet Computer SDK. However, I’m encountering difficulties in efficiently sending the Wasm code to install the new canisters. The current approach involves hardcoding the Wasm code, which is neither scalable nor efficient.
Current Approach: Here’s a simplified version of the relevant part of my code:
motokoCopy code
let nums8 : [Nat8] = Array.map<Nat, Nat8>(Wasm.token_array, Nat8.fromNat);
await ic.install_code({
arg = to_candid(tokenId);
wasm_module = Blob.fromArray(nums8);
mode = #install;
canister_id;
});
Challenges Faced:
- The Wasm code is long, and passing it directly in the code leads to readability issues and potential errors.
- Generating the Wasm code dynamically and passing it in the Candid file byte by byte is time-consuming and not practical.
- Hardcoding the entire Wasm code is not a scalable solution, especially when dealing with multiple canisters.
Request for Assistance: I’m seeking advice on a more efficient approach to handle the installation of dynamically generated canisters. Specifically, I’m looking for suggestions on how to dynamically generate and install the Wasm code without resorting to hardcoding or time-consuming byte-by-byte operations.
Conclusion: If anyone has encountered a similar challenge or has expertise in efficiently handling Wasm code installation for dynamically generated canisters, I would greatly appreciate your insights and suggestions.
Thank you in advance for your assistance!
