How to use the typedi/Container.Container function in typedi

return function(target: Function, key: string, index: number) {

        let container: any;
        try {
            container = require("typedi/Container").Container;
        } catch (err) {
            throw new Error("OrmRepository cannot be used because typedi extension is not installed.");
        }

        container.registerParamHandler({
            type: target,
            index: index,
            getValue: () => {
                const connectionManager: ConnectionManager = container.get(ConnectionManager);
                const connection = connectionManager.getConnection(connectionName);
                return connection.getRepository(cls);
            }
        });
    };
}
