// ...
const mrcAPI = await ApiPromise.create({
// ...
rpc,
types,
});
// commonjs require

Helpful Notes
Option
Optional responses are not mapped to null
and instead return an object with a few properties.
For more details see the code for the Option class.
const optionalExample = await api.rpc.msa.getMsaId(account);
// Does the Option have a value?
if (!optionalExample.isEmpty) {
// Get the value
return optionalExample.value;
}
return null;
Vec
Vector responses are not mapped directly to a JavaScript Array.
Instead they are mapped to the Vec class which does extend Array.
Thus, you can still use map
, forEach
, etc... with responses or access the values directing via .values()
.
