Best alternatives to declarative-forms in 2026
Building a settings dialog or an admin panel usually means wiring up form state, validation, and a component tree just to ask the user for a few fields. declarative-forms skips that: you call one function, describe the fields you want (text, select, checkbox, file, computed fields, arrays), and `await` a promise that resolves with the user's answer — much like the browser's built-in `prompt()`, but for structured, multi-field data instead of a single string. It's framework-agnostic (works with React, Vue, Svelte, Angular, or vanilla JS) because it renders through plain DOM and web components rather than plugging into any particular framework's component model, and it ships with zero runtime dependencies. It handles validation gating, field synchronization, and dialog lifecycle for you, supports reactive field options (show/hide fields based on other answers), and even lets you stack dialogs where an inner dialog can read values from the outer one. It's MIT-licensed, tested with Playwright and Vitest, and still small — about 3 GitHub stars and clearly early-stage.
