Frappe UI Components & Realtime — Implementation Workflows

Step-by-step workflows for building client-side UI. For form scripting see 

frappe-impl-clientscripts
. For server-side API see 
frappe-syntax-serverscripts
.

Version: v14/v15/v16 | Note: v15+ uses Bootstrap 5; Dialog API is stable across all versions.

Quick Decision: Which UI Component?

WHAT do you need?
├── Prompt user for input         → frappe.prompt (simple) or frappe.ui.Dialog (complex)
├── Show a message/alert          → frappe.msgprint / frappe.show_alert / frappe.throw
├── Confirm an action             → frappe.confirm
├── Multi-field data entry popup  → frappe.ui.Dialog with fields
├── Select from a list of records → frappe.ui.form.MultiSelectDialog
├── Full custom page (not a form) → frappe.ui.Page
├── Customize list columns/colors → frappe.listview_settings
├── Visual board for workflow     → Kanban Board (Select field based)
├── Date-based record view        → Calendar View ({doctype}_calendar.js)
├── Hierarchical data display     → Tree View (is_tree DocType)
├── Live updates without refresh  → frappe.publish_realtime + frappe.realtime.on
├── Show background job progress  → frappe.publish_progress
├── Scan barcode/QR code          → frappe.ui.Scanner
└── Custom cell formatting        → formatters in listview_settings or form

for the complete decision tree.

Workflow 1: Dialogs (frappe.ui.Dialog)

Simple Dialog

let d = new frappe.ui.Dialog({
    title: "Enter Details",
    fields: [
        { label: "Full Name", fieldname: "full_name", fieldtype: "Data", reqd: 1 },
        { label: "Email", fieldname: "email", fieldtype: "Data", options: "Email" },
        { label: "Role", fieldname: "role", fieldtype: "Select",
          options: "Developer\nManager\nDesigner" },
    ],
    size: "small",  // "small", "large", or "extra-large"
    primary_action_label: "Create",
    primary_action(values) {
        frappe.call({
            method: "myapp.api.create_user",
            args: values,
            callback(r) {
                if (!r.exc) {
                    frappe.show_alert({ message: "User created", indicator: "green" });
                    d.hide();
                }
            }
        });
    }
});
d.show();

Rule: ALWAYS call 

d.hide()
inside the callback, NEVER before the async call completes.

Dialog with Table Field

let d = new frappe.ui.Dialog({
    title: "Add Items",
    fields: [
        { label: "Customer", fieldname: "customer", fieldtype: "Link",
          options: "Customer", reqd: 1 },
        { fieldtype: "Section Break" },
        { label: "Items", fieldname: "items", fieldtype: "Table",
          in_place_edit: true, reqd: 1,
          fields: [
              { fieldname: "item", label: "Item", fieldtype: "Link",
                options: "Item", in_list_view: 1, reqd: 1 },
              { fieldname: "qty", label: "Qty", fieldtype: "Int",
                in_list_view: 1, default: 1 },
              { fieldname: "rate", label: "Rate", fieldtype: "Currency",
                in_list_view: 1 },
          ],
        },
    ],
    primary_action_label: "Submit",
    primary_action(values) {
        console.log(values);  // { customer: "...", items: [{item, qty, rate}] }
        d.hide();
    }
});
d.show();

Rule: ALWAYS set 

in_list_view: 1
on table child fields you want visible. Fields without it are hidden in the grid.

Multi-Step Dialog

let d = new frappe.ui.Dialog({
    title: "Setup Wizard",
    fields: [
        // Page 1
        { fieldtype: "Section Break", label: "Step 1: Basic Info",
          collapsible: 0 },
        { label: "Name", fieldname: "name", fieldtype: "Data", reqd: 1 },
        // Page 2
        { fieldtype: "Section Break", label: "Step 2: Configuration",
          collapsible: 0 },
        { label: "Option", fieldname: "option", fieldtype: "Select",
          options: "A\nB\nC" },
    ],
    primary_action_label: "Finish",
    primary_action(values) {
        d.hide();
    }
});
d.show();

Key Dialog Methods

MethodPurpose
d.show()
Display the dialog
d.hide()
Close the dialog
d.get_values()
Get all field values as object
d.set_values({field: val})
Set field values
d.get_field("name")
Get a specific field control
d.set_df_property("name", "hidden", 1)
Show/hide fields dynamically
d.disable_primary_action()
Grey out submit button
d.enable_primary_action()
Re-enable submit button

Workflow 2: Messages & Alerts

frappe.msgprint: Modal Message

// Simple message
frappe.msgprint("Record saved successfully");

// With options
frappe.msgprint({
    title: "Warning",
    message: "This action cannot be undone",
    indicator: "orange",     // green, blue, orange, red
    primary_action: {
        label: "Proceed",
        action() { do_something(); }
    }
});

// List of messages
frappe.msgprint({
    title: "Validation Errors",
    message: "Please fix the following:",
    as_list: true,
    indicator: "red",
});

frappe.throw: Error with Exception

// Client-side: shows msgprint and stops execution
frappe.throw("Amount cannot be negative");

# Server-side: raises ValidationError, shown as red msgprint
frappe.throw("Amount cannot be negative")
frappe.throw("Not Permitted", frappe.PermissionError)  # specific exception

Rule: ALWAYS use 

frappe.throw
for validation errors. NEVER use 
frappe.msgprint
for errors — it does not stop execution.

frappe.confirm: Yes/No Dialog

frappe.confirm(
    "Are you sure you want to delete this record?",
    () => { /* Yes callback */ delete_record(); },
    () => { /* No callback (optional) */ }
);

frappe.prompt: Quick Single-Field Input

frappe.prompt(
    { label: "Reason", fieldname: "reason", fieldtype: "Small Text", reqd: 1 },
    (values) => {
        console.log(values.reason);
    },
    "Enter Reason",    // dialog title
    "Submit"           // primary action label
);

// Multiple fields
frappe.prompt([
    { label: "Reason", fieldname: "reason", fieldtype: "Small Text", reqd: 1 },
    { label: "Priority", fieldname: "priority", fieldtype: "Select",
      options: "Low\nMedium\nHigh" },
], (values) => { console.log(values); }, "Details");

frappe.show_alert: Toast Notification

// Simple
frappe.show_alert("Saved");

// With indicator and duration
frappe.show_alert({ message: "Email sent", indicator: "green" }, 5);
// Duration in seconds (default: 7)

Rule: Use 

frappe.show_alert
for non-blocking success messages. Use 
frappe.msgprint
when the user MUST acknowledge.

Workflow 3: List View Customization

Create 

{doctype_name}_list.js
in the DocType directory:

// myapp/doctype/task/task_list.js
frappe.listview_settings["Task"] = {
    // Extra fields to fetch (beyond standard)
    add_fields: ["priority", "status", "assigned_to"],

    // Hide the name column
    hide_name_column: true,

    // Row indicator (colored dot)
    get_indicator(doc) {
        // MUST return [label, color, comma-separated-filter]
        if (doc.status === "Completed") return ["Completed", "green", "status,=,Completed"];
        if (doc.status === "Overdue") return ["Overdue", "red", "status,=,Overdue"];
        return ["Open", "orange", "status,=,Open"];
    },

    // Custom column formatters
    formatters: {
        priority(val) {
            const colors = { High: "red", Medium: "orange", Low: "green" };
            return `<span class="indicator-pill ${colors[val] || ""}">${val}</span>`;
        }
    },

    // Row action button
    button: {
        show(doc) { return doc.status === "Open"; },
        get_label() { return __("Complete"); },
        get_description(doc) { return __("Mark {0} as complete", [doc.name]); },
        action(doc) {
            frappe.xcall("myapp.api.complete_task", { task: doc.name })
                .then(() => cur_list.refresh());
        }
    },

    // Lifecycle hooks
    onload(listview) {
        listview.page.add_inner_button("Export", () => export_tasks());
    },

    refresh(listview) {
        // Runs on every list refresh
    },

    // Default filters
    filters: [["status", "!=", "Cancelled"]],
};

Rule: ALWAYS return a 3-element array from 

get_indicator
. The third element is the filter string for click-to-filter.

Workflow 4: Custom Page (frappe.ui.Page)

Step 1: Register in hooks.py

# hooks.py
page_js = { "my-custom-page": "public/js/my_custom_page.js" }

Step 2: Create page definition

// myapp/myapp/my_custom_page/my_custom_page.js
frappe.pages["my-custom-page"].on_page_load = function(wrapper) {
    let page = frappe.ui.make_app_page({
        parent: wrapper,
        title: "My Custom Page",
        single_column: true,
    });

    // Primary action button
    page.set_primary_action("Create", () => create_new(), "octicon octicon-plus");

    // Secondary action
    page.set_secondary_action("Refresh", () => refresh_data());

    // Dropdown menu
    page.add_menu_item("Export CSV", () => export_csv());
    page.add_menu_item("Settings", () => frappe.set_route("Form", "My Settings"));

    // Inner toolbar buttons
    page.add_inner_button("Update All", () => update_all());
    page.add_inner_button("New Post", () => new_post(), "Make");  // grouped

    // Toolbar filter fields
    let status_field = page.add_field({
        label: "Status",
        fieldtype: "Select",
        fieldname: "status",
        options: ["", "Open", "Closed", "Cancelled"],
        change() { refresh_data(); }
    });

    // Status indicator
    page.set_indicator("Active", "green");

    // Content area
    $(page.body).html(`<div class="my-page-content"></div>`);

    // Load initial data
    refresh_data();
};

Key Page Methods

MethodPurpose
page.set_title(title)
Set page heading
page.set_indicator(label, color)
Status badge (green/red/orange/blue)
page.set_primary_action(label, fn, icon)
Main action button
page.set_secondary_action(label, fn)
Secondary button
page.add_menu_item(label, fn)
Dropdown menu entry
page.add_inner_button(label, fn, group)
Toolbar button (optional group)
page.add_field({...})
Add filter/input to toolbar
page.get_form_values()
Get all toolbar field values
page.clear_fields()
Remove all toolbar fields
page.clear_primary_action()
Remove primary button

Workflow 5: Calendar View

Create 

{doctype}_calendar.js
in the DocType directory:

// myapp/doctype/event/event_calendar.js
frappe.views.calendar["Event"] = {
    field_map: {
        start: "starts_on",
        end: "ends_on",
        id: "name",
        title: "subject",
        allDay: "all_day",
        color: "color",
    },
    gantt: true,  // Enable Gantt view toggle
    get_events_method: "myapp.api.get_events",  // Optional custom event source
    filters: [
        { fieldtype: "Link", fieldname: "event_type", label: "Type",
          options: "Event Type" }
    ],
};

Rule: ALWAYS map 

start
and 
end
to actual Date or Datetime fields on the DocType. Missing mappings cause blank calendars.

Workflow 6: Kanban Board

Kanban boards work on any DocType with a Select field. No code needed:

  1. Open List View → sidebar → Kanban → New Kanban Board
  2. Select the Select field (e.g., 
    status
    ) — options become columns
  3. Save — cards are draggable between columns

Rule: NEVER create Kanban boards for DocTypes without a Select field. See 

references/examples.md
for programmatic configuration.

Workflow 7: Realtime Updates (Socket.IO)

Server: Publish Events

# Broadcast to all users
frappe.publish_realtime("task_updated", {"task": task.name, "status": "Done"})

# Send to specific user
frappe.publish_realtime("notification", {"msg": "Your report is ready"},
    user="admin@example.com")

# Send to users viewing a specific document
frappe.publish_realtime("doc_updated", {"field": "status"},
    doctype="Task", docname="TASK-001")

# ALWAYS use after_commit=True in document events
frappe.publish_realtime("order_created", message, after_commit=True)

Client: Subscribe to Events

// Listen for events
frappe.realtime.on("task_updated", (data) => {
    frappe.show_alert({ message: `Task ${data.task}: ${data.status}`, indicator: "green" });
    cur_list && cur_list.refresh();
});

// Stop listening
frappe.realtime.off("task_updated");

Progress Indicator

# Server: publish progress during long operations
def process_items(items):
    total = len(items)
    for i, item in enumerate(items):
        process(item)
        frappe.publish_progress(
            percent=(i + 1) / total * 100,
            title="Processing Items",
            description=f"Processing {item.name}",
        )

Rule: ALWAYS use 

after_commit=True
when publishing from document events. Without it, the event fires even if the transaction rolls back.

Realtime Rooms

(default)All System UsersGlobal notifications

Single userPersonal alerts

Workflow 8: Scanner API (Barcode/QR)

// Single scan — closes after first scan
new frappe.ui.Scanner({
    dialog: true, multiple: false,
    on_scan(data) {
        frappe.set_route("Form", "Item", data.decodedText);
    }
});

// Continuous scanning — stays open for multiple scans
let scanner = new frappe.ui.Scanner({
    dialog: true, multiple: true,
    on_scan(data) { add_item_to_list(data.decodedText); }
});
// Stop: scanner.stop_scan() or close the dialog

Rule: ALWAYS set 

multiple: false
for single-item lookups. See 
references/examples.md
for a full barcode-in-Stock-Entry example.

Anti-Patterns Summary

Anti-PatternCorrect Approach
frappe.msgprint
for errors		Use 
frappe.throw
— it stops execution
Hiding dialog before async completesHide in the callback: 
callback() { d.hide(); }
Synchronous API calls in dialogsALWAYS use 
frappe.call
/ 
frappe.xcall
(async)
Missing 
in_list_view
on table fields		Set 
in_list_view: 1
on visible columns
publish_realtime
without 
after_commit
ALWAYS use 
after_commit=True
in doc events
Kanban on DocType without Select fieldKanban requires a Select field for columns
Missing start/end in calendar field_mapALWAYS map both 
start
and 
end
fields
2-element array from get_indicatorALWAYS return 3 elements: [label, color, filter]
