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

// Create workspace (ES5 ONLY!)
var workspace = new GlideRecord("sys_aw_workspace")
workspace.initialize()

workspace.setValue("name", "asset_tracker_workspace")
workspace.setValue("title", "Asset Tracker")
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")

// App scope
workspace.setValue("sys_scope", appScopeSysId)

// Features
workspace.setValue("agent_assist_enabled", false)
workspace.setValue("contextual_side_panel_enabled", true)

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",
  table: "x_myco_asset_track_asset_item",
  filter: "u_assigned_user=javascript:gs.getUserID()",
  columns: ["number", "name", "u_purchase_date", "u_warranty_end", "state"],
})

createWorkspaceList(workspaceSysId, {
  name: "Expiring Warranties",
  table: "x_myco_asset_track_asset_item",
  filter: "u_warranty_endBETWEENjavascript:gs.daysAgoStart(0)@javascript:gs.daysAgoEnd(-30)",

  orderBy: "u_warranty_end",
})

UI Builder Pages (ES5)

Page Configuration

// Create UI Builder page (ES5 ONLY!)
// Note: Full page creation typically done via UI Builder

var page = new GlideRecord("sys_ux_page")
page.initialize()

page.setValue("name", "asset_dashboard")
page.setValue("title", "Asset Dashboard")
page.setValue("description", "Dashboard for asset overview")

// Page type
page.setValue("page_type", "workspace")

// Workspace link
page.setValue("workspace", workspaceSysId)

// Scope
page.setValue("sys_scope", appScopeSysId)

page.insert()

Custom Component (Macroponent)

// Create custom macroponent definition (ES5 ONLY!)
// Note: Actual components created via UI Builder

var component = new GlideRecord("sys_ux_macroponent")
component.initialize()

component.setValue("name", "asset_summary_card")
component.setValue("label", "Asset Summary Card")
component.setValue("description", "Displays asset summary information")

// Component category
component.setValue("category", "data_visualization")

// Scope
component.setValue("sys_scope", appScopeSysId)

// Properties (inputs)
component.setValue(
  "properties",
  JSON.stringify([
    { name: "title", type: "string", label: "Card Title" },
    { name: "assetTable", type: "string", label: "Asset Table" },
    { name: "filter", type: "string", label: "Filter" },
  ]),
)

component.insert()

Data Brokers (ES5)

Create Data Broker

// Data broker for workspace data (ES5 ONLY!)
// Data brokers provide data to UI Builder pages

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",
  "(function getData(inputs) {\n" +
    "    var result = {\n" +
    "        total: 0,\n" +
    "        assigned: 0,\n" +
    "        available: 0,\n" +
    "        expiring_warranty: 0\n" +
    "    };\n" +
    "    \n" +
    '    var ga = new GlideAggregate("x_myco_asset_track_asset_item");\n' +
    '    ga.addAggregate("COUNT");\n' +
    '    ga.groupBy("state");\n' +
    "    ga.query();\n" +
    "    \n" +
    "    while (ga.next()) {\n" +
    '        var count = parseInt(ga.getAggregate("COUNT"), 10);\n' +
    "        result.total += count;\n" +
    "        \n" +
    '        var state = ga.getValue("state");\n' +
    '        if (state === "in_use") {\n' +
    "            result.assigned = count;\n" +
    '        } else if (state === "available") {\n' +
    "            result.available = count;\n" +
    "        }\n" +
    "    }\n" +
    "    \n" +
    "    // Expiring warranties\n" +
    '    var expiring = new GlideAggregate("x_myco_asset_track_asset_item");\n' +
    '    expiring.addQuery("u_warranty_end", "BETWEEN", "javascript:gs.daysAgoStart(0)@javascript:gs.daysAgoEnd(-30)");\n' +
    '    expiring.addAggregate("COUNT");\n' +
    "    expiring.query();\n" +
    "    \n" +
    "    if (expiring.next()) {\n" +
    '        result.expiring_warranty = parseInt(expiring.getAggregate("COUNT"), 10);\n' +
    "    }\n" +
    "    \n" +
    "    return result;\n" +
    "})(inputs);",
)

broker.setValue("sys_scope", appScopeSysId)

broker.insert()

Application Deployment (ES5)

Create Update Set

// Create update set for app deployment (ES5 ONLY!)
function createAppUpdateSet(appName, description) {
  var updateSet = new GlideRecord("sys_update_set")
  updateSet.initialize()
  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!)
function prepareAppExport(appScope) {
  // Validate all components
  var issues = []

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

  while (dependency.next()) {
    if (!isDependencyInstalled(dependency.getValue("dependency"))) {
      issues.push("Missing dependency: " + dependency.dependency.getDisplayValue())
    }
  }

  // Validate update sets
  var updateSet = new GlideRecord("sys_update_set")
  updateSet.addQuery("application.scope", appScope)
  updateSet.addQuery("state", "in progress")
  updateSet.query()

  while (updateSet.next()) {
    issues.push("Open update set: " + updateSet.getValue("name"))
  }

  return {
    ready: issues.length === 0,
    issues: issues,
  }
}

Best Practices

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