Sample serv (Port = user.serv) shows how user can extend basic serv API with help of semantic-transact SQL builder

function branch: a = "A" | "B" | "C";
The js client request should do something like this:

var conn = jconsts.conn;
function saveTooleA() {
        var dat = {borrowId: 'borrow-001', items: []};
        dat.items.push(['item001', 3]); // return 3 of tiem001

        var usrReq = new jvue.UserReq(conn, "r_tools_borrows")
                                                // turn back tools - or any function branch tag handled by tools.serv
                                                .a("A")

                                                // or reaplace these 2 set() with data(dat)
                                                .set('borrowId', 'borrow-001')
                                                .set('items', [['item001', 3]]);

        var jmsg = ssClient
                // ssClient's current user action is handled by jeasy when loading menu
                .usrCmd('save') // return ssClient itself
                .userReq(conn, engports.tools, usrReq); // return the AnsonMsg<UserReq> object

        // You should get sqls at server side like this:
        // delete from r_tools_borrows where borrowId = 'borrow-001'
        // insert into detailsTbl  (item001) values ('3.0')
        // update borrowTbl  set total= where borrowId = 'borrow-001'
        ssClient.commit(jmsg, function(resp) {
                                EasyMsger.ok(EasyMsger.m.saved);
                        }, EasyMsger.error);
