dioxus-bootstrap-css

Bootstrap 5.3 components for Dioxus. The crate uses real Bootstrap CSS and Bootstrap Icons, bundles assets for offline-first apps, and replaces Bootstrap JavaScript behavior with Dioxus signals.

Live showcase: https://mik-tf.github.io/dioxus-bootstrap-css/

API docs: https://docs.rs/dioxus-bootstrap-css

Repository: https://github.com/mik-tf/dioxus-bootstrap-css

Short name: dbcss means dioxus-bootstrap-css. The full crate name is long, so issues and notes may use the abbreviation.

Design rule: if Bootstrap does it, this crate should expose a typed Dioxus way to express it. If Bootstrap does not do it, this crate should not invent it.

Why

• Pixel fidelity by using Bootstrap 5.3 CSS instead of a reimplementation.
• Zero Bootstrap JavaScript; interactions are driven by Dioxus state.
• Offline-first CSS and icon assets through BootstrapHead.
• Type-safe component props for color, size, state, slots, and variants.
• Migration tools for converting raw Bootstrap RSX into typed components.

Quick Start

cargo add dioxus-bootstrap-css

Or pin it in Cargo.toml:

[dependencies]
dioxus = { version = "0.7", features = ["web"] }
dioxus-bootstrap-css = "0.5"

use dioxus::prelude::*;
use dioxus_bootstrap_css::prelude::*;

fn main() {
    dioxus::launch(app);
}

fn app() -> Element {
    let theme = use_signal(|| Theme::Dark);

    rsx! {
        ThemeProvider { theme }
        BootstrapHead {}
        Container { class: "py-4",
            Row { class: "g-3",
                Col { md: ColumnSize::Span(6),
                    Card {
                        header: rsx! { "Getting Started" },
                        body: rsx! {
                            p { "Bootstrap in Dioxus - fully offline, fully Rust." }
                            Button { color: Color::Primary, "Launch" }
                        },
                    }
                }
                Col { md: ColumnSize::Span(6),
                    Alert { color: Color::Success, "Everything works out of the box." }
                }
            }
        }
    }
}

Components

Layout and head:

• BootstrapHead
• ThemeProvider, ThemeToggle
• Container, Row, Col

Content and data display:

• Button, ButtonGroup, ButtonToolbar
• Card, Alert, Badge, Icon, Spinner
• Progress, ProgressBar, Placeholder, Figure, Ratio
• Table, ListGroup, Pagination

Forms:

• FormGroup, Input, Select, Textarea
• Checkbox, Radio, Switch, Range
• FloatingLabel, InputGroup, FormFeedback, FormText

Interactive components:

• Modal, Dropdown, Collapse, Tabs, TabList
• Accordion, Offcanvas, Toast, Carousel
• Tooltip, Popover, Scrollspy
• Navbar, NavbarToggler, NavbarCollapse, NavbarNav, Nav, Breadcrumb

Dark Mode

let theme = use_signal(|| Theme::Dark);

rsx! {
    ThemeProvider { theme }
    BootstrapHead {}
    ThemeToggle { theme }
}

ThemeProvider sets data-bs-theme on the document and lets Bootstrap handle the rest.

Migration From Bootstrap HTML

Convert Bootstrap HTML or raw Bootstrap RSX by replacing component classes with typed components:

Button {
    color: Color::Secondary,
    outline: true,
    size: Size::Sm,
    class: "border-0",
    "Refresh"
}

Key principles:

• Use Bootstrap utility classes (small, py-2, mb-0) for layout and spacing.
• Use component props (color, outline, size, header_class, responsive) for component intent.
• Replace Bootstrap JavaScript with Dioxus signals.
• Treat tools/check-no-raw-bootstrap.mjs as a completeness gate, not a visual-fidelity proof.
• Let the converter map Bootstrap intent to props, flag unsafe cases instead of guessing, then prove fidelity with Playwright screenshots.

See docs/04_migration.md for the complete workflow.

Tools

node tools/migrate-bootstrap-rsx.mjs path/to/app/src
node tools/migrate-bootstrap-rsx.mjs --check path/to/app/src
node tools/migrate-bootstrap-rsx.mjs --write path/to/app/src

node tools/check-no-raw-bootstrap.mjs path/to/app/src
npm run lint:bootstrap

tools/README.md documents the converter and migration gate.

Examples

• examples/showcase demonstrates the component set.
• examples/dashboard is a compact admin dashboard example.
