1handler: async ({ io }) => {
2  // simple text input, io.textInput would render a text field
3  // and return the user input as a string
4  const userName = await io.textInput({
5    label: 'Enter your name',
6  })
7  // conditional logic based on user input
8  if (name === 'Elon') {
9    const email = await io.textInput({
10      label: 'Enter your email',
11    })

Rendered Application

Starting application...

Beautiful Forms Without the Frontend Fuss

Text fields, dropdowns, checkboxes, and date pickers - all the form basics your business apps need.

const name = await io.textInput({ 
  label: 'Enter your name'
})

The Hard Stuff Made Easy

Interactive data tables with selection, drag-and-drop file uploads, and advanced multi-field forms for sophisticated data entry.

const orders = await io.tableInput({
  label: 'Orders to refund',
  description: 'Select all the payments to be refunded',
})

Universal Validation Logic

Write validation rules once and they work across all input.

const email = await io.email({
  label: 'Email',
  validationSchema: z.email().endsWith('prodios.com')
})

Complex Logic Without Complex Code

Build dynamic workflows that adapt based on user inputs and business rules without complex state management.

const preferredCurrency = await io.selectInput({ // })
if (preferredCurrency === 'USD') {
  const userDetails = await io.form({ // })
}

Live Updates Without WebSocket Hell

Show live progress for long-running operations with automatic updates and user-friendly status messages

const progress = await io.progress({
  title: 'Refunding Orders', itemsInQueue: orders.length
})
for (const order of orders) {
  await refundOrder(order)
  await progress.incrementOne()
}

Dashboards That Actually Impress

Charts, KPI cards, data tables, and analytics—everything needed for professional business dashboards.

block.barChart({
  title: 'Sales breakdown by region',
  data: salesData,
  index: 'date'
})

Workflow

Chain Steps. Build Complex Workflows

Define modular steps and connect them with clear, code-defined flows. Tool Forge automatically orchestrates the execution, transitions, and UI for each stage.
