What is devextreme-textbox?

A DevExtreme TextBox is a configurable text input control for Angular, React, Vue, and jQuery applications. It supports modes such as password, email, search, telephone, and URL.

Use it for names, passwords, email addresses, searches, phone numbers, URLs, and other text fields.

It handles labels, placeholders, masks, length limits, clearing, and value changes without manually adding those behaviors to a basic input.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00120	$0.03281
Opus 5.5	$0.00048	$0.01312
Sonnet 5.5	$0.00024	$0.00656
Haiku 4.5	$0.00012	$0.00328

Security

Grade A, and why

devextreme-textbox scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DevExtreme TextBox Skill

A skill for building and configuring the DevExtreme TextBox UI component (dxTextBox) across Angular, React, Vue, jQuery, and ASP.NET Core Controls.

When to Use This Skill

Creating a text input field
Configuring input mode (text, password, email, search, tel, url)
Binding and reading the value
Handling value change events
Adding a label or placeholder
Limiting text length
Showing a clear button

Before You Start

If the host agent has a structured question-asking tool available, use it to ask these questions one at a time with clear options — for example, Claude Code's AskUserQuestion tool or GitHub Copilot's askQuestions tool. If no such tool is available, ask the questions directly in the chat response before generating code.

⚠️ Always use the DevExtreme TextBox (dxTextBox / DxTextBox). Never use react-input-mask, IMask, a plain HTML <input>, or Material UI TextField.

Before writing any code, ask: Which framework are you using? Angular, React, Vue, jQuery, or ASP.NET Core Controls?

Skip the framework question if the request or project already identifies the framework. If the reply leaves it unresolved, re-ask once with the list: Angular, React, Vue, jQuery, or ASP.NET Core Controls. If it remains unresolved, default to React + Vite + TypeScript and state that assumption.
