I have this line in my file: import * as secp256k1 from "npm:@noble/secp256k1";
It works fine locally (deno run)
When I try to deno deploy, it cannot find the module.
I read this is because deno deploy doesn't yet support npm:.
To circumvent it I tried using import * as secp256k1 from "https://deno.land/x/secp256k1/mod.ts", but this doesn't work locally. I'm getting
error: Relative import path "crypto" not prefixed with / or ./ or ../
If you want to use a built-in Node module, add a "node:" prefix (ex. "node:crypto").
at https://deno.land/x/secp256k1@1.7.1/index.ts:6:29
how can I fix this? thanks.
The documentation for /x/secp256k1 says:
To use the module with Deno, you will need import map
In this case, you will need to polyfill node's crypto. In the future this will be done using node:crypto, but for now deploy does not support this and you must use https://deno.land/std@0.177.0/node/crypto.ts.
Your import map should look something like:
{
"imports": {
"crypto": "https://deno.land/std@0.177.0/node/crypto.ts"
}
}
Here is an example of using import maps with deploy (it's just how you would expect): https://github.com/satyarohith/import_map
