decodeUnknownPromise | Effect Schema

decodeUnknownPromise returns a Promise instead of throwing or returning Exit / Option.

If decoding succeeds, the Promise resolves with the decoded value.
If decoding fails, the Promise rejects with a SchemaIssue.Issue.

const decode = Schema.decodeUnknownPromise(schema);

const decoded = await decode({ name: "Alice", age: 30 });

console.log("Decoded Value:", decoded);

14
// Error path

try {
16
  await decode({ name: 42, age: "30" }, { errors: "all" });
17
} catch (issue) {
18
  if (SchemaIssue.isIssue(issue)) {
19
    console.log("Error Message:", String(issue));
20
    console.log("Issue Tree:", issue);

  }

}

Use decodeUnknownPromise when you want schema decoding to fit into async/await and Promise-based code.
