Question

How can we combine all our javascript functions into a single reusable location using Server Files?

Answer 1

Put the functions in one JavaScript file as a managed web asset, expose them under a single namespace, and include the file from one coach view that every coach carries - then every client-side script and control event can call them (question 3123 shows the same for CSHS scripts). A structure that stays maintainable as the file grows:

// common.js  (managed web file "common.js" or inside common.zip/js/common.js)
(function (ns) {
  // validation
  ns.isEmail = function (s) { return /^[^@\s]+@[^@\s]+\.[^@\s]+$/.test(s || ""); };
  ns.required = function (control, msg) { var ok = !!control.getData(); control.setValid(ok, ok ? "" : (msg || "Required")); return ok; };
  // formatting
  ns.money = function (n, cur) { return (cur || "EUR") + " " + (Math.round((n || 0) * 100) / 100).toFixed(2); };
  ns.date  = function (d) { d = new Date(d); return isNaN(d) ? "" : d.toISOString().slice(0, 10); };
  // UI helpers
  ns.notify = function (alertControl, style, text) { alertControl.setColorStyle(style); alertControl.setText(text); alertControl.setVisible(true); };
  // REST helper (BPM REST API, CSRF aware)
  ns.rest = function (method, path, body, cb) { /* see the answers on REST calls from coach views */ };
  ns.version = "1.3.0";
})(window.myco = window.myco || {});

1. Coach view Common Library (no layout) > Behavior > Included Scripts: common.js. Add this view to a header view that all coaches use, so nobody forgets it.
2. Use from anywhere: myco.required(${Email}, "E-mail is required"), myco.money(${Total}.getData()).
3. Version the file name when you change signatures (common-1.3.js), keep the source in Git, minify in the build if it grows.

Server-side functions cannot share a file; there the equivalent is a toolkit service per function (or a Java helper class). Keep browser and server helpers separate - tw.local semantics differ.
