JavaScript Libraries for Enterprise UI: Grid, Chart and Form Options Compared

Most comparisons of JavaScript libraries look at one category at a time: the best grid, the best chart library, the best form library. Enterprise UIs don’t work one category at a time. The same screen shows a grid of orders, a chart of the same orders, and a form for editing the selected one, and all three have to agree on the data, the validation rules, and the look.

This guide compares grid, chart and form options against the criteria that matter for enterprise UI, then does what single-category lists can’t: it compares the four ways to put them together, and what each means for integration, consistency and long-term cost.

What enterprise UI demands

These criteria are used throughout the comparison:

The first four criteria can be judged library by library. The last four only show up when libraries are combined, which is why the stack comparison later in this guide matters most.

Grid options compared

The grid is usually the most demanding component in an enterprise UI. Here’s how the main options compare on the criteria above:

What stands out: several grids match each other on depth and scale. The difference is the “shares data” column. Only a grid that’s part of a framework with a shared data layer can stay in sync with charts and forms without integration code.

Chart options compared

What stands out: for chart-only needs, Highcharts and ECharts are hard to beat on range. For dashboards where a chart must reflect exactly what the grid next to it shows, filters, edits and all, sharing one data store matters more than chart variety.

Form options compared

Forms are where enterprise UIs differ most from consumer apps: dozens of fields, type-ahead dropdowns, date ranges, dense multi-column layouts, and validation that must match the server’s rules. It helps to separate what a “form library” actually covers:

• Form state and validation: values, touched and dirty tracking, rules and error messages.
• Field components: text, number, date, time, type-ahead dropdowns, tag fields and more.
• Form layouts: columns, field sets, tabs and collapsible sections.
• Binding to records: loading a record into the form and writing changes back.

Most JavaScript form libraries cover the first item only. The rest comes from your component library, or your own code.

What stands out: the open-source form libraries are excellent at form state, and leave fields, layouts and record binding to you. Ext JS is the only option here that covers all four, and the only one where the same fields work as grid cell editors.

The real comparison: four ways to build an enterprise UI stack

Once grid, chart and form choices are combined, four kinds of stack emerge:

• Stack A, all open source: a free grid (such as TanStack Table or Tabulator), a free chart library (such as ECharts or Chart.js), a form library with a schema validator, and a general component kit for fields.
• Stack B, commercial grid plus open source: a commercial grid (such as AG Grid Enterprise) with open-source charts, forms and component kit.
• Stack C, a commercial suite: grid, charts and input components from one vendor’s suite, often with your own form state library.
• Stack D, one framework: Ext JS, used directly or in React through ReExt, with grid, charts, forms, layouts and the data layer together.

The table makes a simple trade-off visible. Moving from Stack A to Stack D, license cost rises and integration work falls. For apps with a few simple screens, Stack A or B is often right. For enterprise application development with hundreds of data screens maintained for years, the integration work in Stacks A and B usually costs far more than a license, which is where Stack D pays off.

Stack D in practice: one model, one set of rules, grid and form together

Here’s what “shared data” and “shared rules” look like in Ext JS. The validation rules live once, on the model. The grid and the form both work on the same records, and the form shows errors straight from the model’s rules.

The model: fields and validation, defined once

    Ext.define('App.model.Customer', {
      extend: 'Ext.data.Model',
      fields: [
        { name: 'name', type: 'string' },
        { name: 'email', type: 'string' },
        { name: 'region', type: 'string' },
        { name: 'creditLimit', type: 'float' },
        { name: 'since', type: 'date', dateFormat: 'Y-m-d' },
      ],
      validators: {
        name: 'presence',
        email: 'email',
        region: { type: 'inclusion', list: ['EMEA', 'APAC', 'AMER'] },
        creditLimit: { type: 'range', min: 0, max: 1000000 },
      },
    });

The view: a grid and a form on the same records

    Ext.define('App.view.customers.Customers', {
      extend: 'Ext.panel.Panel',
      xtype: 'customers',
      title: 'Customers',
      layout: 'border',

      viewModel: {
        stores: {
          customers: {
            model: 'App.model.Customer',
            autoLoad: true,
            proxy: { type: 'ajax', url: '/api/customers', reader: { type: 'json', rootProperty: 'data' } },
          },
        },
      },

      items: [{
        region: 'center',
        xtype: 'grid',
        bind: { store: '{customers}', selection: '{customer}' },
        plugins: [{ ptype: 'cellediting', clicksToEdit: 1 }],
        columns: [
          { text: 'Name', dataIndex: 'name', flex: 1, editor: 'textfield' },
          { text: 'Region', dataIndex: 'region', width: 110,
            editor: { xtype: 'combobox', store: ['EMEA', 'APAC', 'AMER'], forceSelection: true } },
          { text: 'Credit limit', dataIndex: 'creditLimit', width: 140,
            xtype: 'numbercolumn', format: '$0,000', editor: 'numberfield' },
        ],
      }, {
        region: 'east',
        xtype: 'form',
        width: 320,
        split: true,
        collapsible: true,
        title: 'Customer details',
        bodyPadding: 12,
        modelValidation: true,      // show errors from the model's validators
        defaults: { anchor: '100%' },
        items: [
          { xtype: 'textfield', fieldLabel: 'Name', bind: '{customer.name}' },
          { xtype: 'textfield', fieldLabel: 'Email', bind: '{customer.email}' },
          { xtype: 'combobox', fieldLabel: 'Region', store: ['EMEA', 'APAC', 'AMER'],
            bind: '{customer.region}' },
          { xtype: 'numberfield', fieldLabel: 'Credit limit', bind: '{customer.creditLimit}' },
          { xtype: 'datefield', fieldLabel: 'Customer since', bind: '{customer.since}' },
        ],
      }],
    });

What this gives you without integration code:

• One source of truth. The grid and form edit the same record; a change in either appears in the other immediately.
• One set of rules. The model’s validators drive the form’s error messages, and any save path, including grid edits, can check record.isValid() against the same rules.
• One set of fields. The combobox and number field in the grid editors are the same components as in the form, so they look and behave identically.
• One theme and one layout system, with a resizable, collapsible detail panel.

React teams get the same model, stores and ui components through ReExt, which renders Ext JS grids, forms and charts as React elements.

How to choose

Match the stack to how your screens combine grids, charts and forms:

Questions to settle before deciding

1. How often do grids, charts and forms appear on the same screen? The more often, the more shared data and shared rules are worth.
2. Where do your validation rules live today? If they’re duplicated across grid editors, forms and the server, a model-based approach removes a common source of bugs.
3. How many screens will you build and maintain over five years? Integration work grows with every screen; a license doesn’t.
4. Who supports each piece? Count the maintainers you’d depend on, and check how each handles security fixes and new React frameworks or browser releases.

Frequently asked questions

Which JavaScript libraries are best for enterprise UI?

It depends on how your screens combine components. For single-purpose needs, specialist libraries such as AG Grid, Highcharts, ECharts or React Hook Form are strong choices. For enterprise apps where grids, charts and forms share data and rules on the same screens, a framework such as Ext JS covers all three together.

What is the best JavaScript form library for enterprise apps?

Open-source libraries such as React Hook Form and TanStack Form handle form state and validation well, but leave field components, layouts and record binding to you. Ext JS forms include all of those, and their fields double as grid cell editors.

Do I need a separate chart library if I use a data grid library?

Usually, yes, unless your grid is part of a framework or suite that includes charts. With separate libraries, you’ll also need code to keep the chart in sync with the grid’s filters and edits.

How do I keep grid editing and form validation consistent?

Define validation rules once, close to the data, and use the same field components in grid editors and forms. In Ext JS, model validators and shared field components provide both.

Can I use Ext JS grids, charts and forms in React?

Yes. ReExt brings Ext JS components into React applications, and ReExt 1.2.0 supports Ext JS 8.0.

Compare stacks, not just libraries

Grid, chart and form libraries are easy to compare one by one, and many excellent options exist in each category. Enterprise UIs, though, are judged on how those pieces work together: whether they share data, validation rules, field components and a theme, and how much code it takes to make them.

If your screens combine all three every day, Ext JS gives you one model, one set of rules and one set of components, and ReExt brings the same to React.
