How can I get the inferred type using TypeScripts compiler API?

Question

I'm writing a TS language server plugin and need to get the inferred type for an object literal:

const x: TypeA = {};

I have a Node for the opening brace by using:

const node = (ts2 as any).getTouchingToken(fileSrc, m.index);
if(ts.isObjectLiteralExpression(node.parent)) {
    const t = checker.getTypeAtLocation(node.parent);
    // "escapedName": "__object"
    // Want to get the inferred type, and also all properties of that type.
}

This question answers for primitive types: How do you get inferred type from a typescript AST?
