Key Tables

Application Development (ES5)

Create Scoped Application

// Create scoped application (ES5 ONLY!)
var app = new GlideRecord("sys_scope")
app.initialize()

// Basic info
app.setValue("name", "IT Asset Tracker")
app.setValue("scope", "x_myco_asset_track")
app.setValue("short_description", "Track IT assets across the organization")
app.setValue("version", "1.0.0")

// Vendor
app.setValue("vendor", "My Company")
app.setValue("vendor_prefix", "x_myco")

// License
app.setValue("licensable", true)

app.insert()

Create Application Table

// Create table in scoped app (ES5 ONLY!)
function createAppTable(scope, tableDef) {
  var table = new GlideRecord("sys_db_object")
  table.initialize()

  table.setValue("name", scope + "_" + tableDef.name)
  table.setValue("label", tableDef.label)
  table.setValue("super_class", tableDef.extends || "task")

  // Scope assignment
  table.setValue("sys_scope", getAppSysId(scope))

  // Options
  table.setValue("is_extendable", tableDef.extendable || false)
  table.setValue("create_access_controls", true)

  table.insert()

  // Create fields
  if (tableDef.fields) {
    for (var i = 0; i < tableDef.fields.length; i++) {
      createField(scope + "_" + tableDef.name, tableDef.fields[i])
    }
  }

  return table.getUniqueValue()
}

// Example
createAppTable("x_myco_asset_track", {
  name: "asset_item",
  label: "Asset Item",
  extends: "cmdb_ci",
  fields: [
    { name: "u_purchase_date", label: "Purchase Date", type: "glide_date" },
    { name: "u_warranty_end", label: "Warranty End", type: "glide_date" },
    { name: "u_assigned_user", label: "Assigned User", type: "reference", reference: "sys_user" },
  ],
})

Workspace Configuration (ES5)

Create Custom Workspace

workspace.setValue("description", "Workspace for IT asset management")

// Primary table
workspace.setValue("primary_table", "x_myco_asset_track_asset_item")

// URL
workspace.setValue("url", "asset-tracker")

// Branding
workspace.setValue("icon", "laptop")
workspace.setValue("color", "#2E7D32")

workspace.insert()

Configure Workspace Lists

// Create workspace list (ES5 ONLY!)
function createWorkspaceList(workspaceSysId, listDef) {
  var list = new GlideRecord("sys_aw_list")
  list.initialize()

  list.setValue("workspace", workspaceSysId)
  list.setValue("name", listDef.name)
  list.setValue("table", listDef.table)

  // Filter
  list.setValue("filter", listDef.filter || "")

  // Columns
  list.setValue("columns", listDef.columns.join(","))

  // Sorting
  if (listDef.orderBy) {
    list.setValue("order_by", listDef.orderBy)
    list.setValue("order_by_desc", listDef.orderDesc || false)
  }

  // Grouping
  if (listDef.groupBy) {
    list.setValue("group_by", listDef.groupBy)
  }

  list.insert()

  return list.getUniqueValue()
}

// Example lists
createWorkspaceList(workspaceSysId, {
  name: "My Assets",

var broker = new GlideRecord("sys_ux_data_broker")
broker.initialize()

broker.setValue("name", "asset_stats")
broker.setValue("label", "Asset Statistics")

// Data source type
broker.setValue("type", "script")

// Script to fetch data (ES5 ONLY!)
broker.setValue(
  "script",

    "    \n" +
    "    return result;\n" +
    "})(inputs);",

  updateSet.setValue("name", appName + " - " + new GlideDateTime().getDate())
  updateSet.setValue("description", description)
  updateSet.setValue("application", getAppSysId(appName))
  updateSet.setValue("state", "in progress")
  return updateSet.insert()
}

Export Application

// Prepare app for export (ES5 ONLY!)

  // Check for missing dependencies
  var dependency = new GlideRecord("sys_app_dependency")
  dependency.addQuery("app.scope", appScope)

  while (dependency.next()) {

Best Practices

1. Naming Conventions - Consistent prefixes
2. Scoped Apps - Use scope isolation
3. Reusable Components - Modular design
4. Data Brokers - Efficient data fetching
5. Workspace Design - User-focused layouts
6. Testing - ATF tests for apps
7. Documentation - App documentation
8. ES5 Only - No modern JavaScript syntax
