@labir/react-bridge NPM

React binding to @labir/core

Documentation and examples at https://labir.vercel.app.

This package provides fundamental integration of @labir/core in React:

context and hooks for @labir/core classes
hooks for creation of buttons, dropdowns & modals that will controll the @labir/core internal state
three specific UI components for thermal imaging: Histogram, ThermalRange ThermalInastance

See @labir/core documentation to understand its concept.

Foundation of a final UI

This package creates the main logic and bindings to the @labir/core. But the final UI needs to be implemented in a particular SCSS framework. We have the following implamentations:

@labir/tailwind - TailwindCSS & NextUI
@labir/emotion - @emotion/react

Components in those packages use hooks from @labir/react-bridge to handle the logic, but the styling is done individually.

Only three specific components are provided by this package (see below). Their styling is inline and absolutely isolated from any other CSS that might appear on the page.

Context

All componenst need to be nested by <ThermalProvider /> which creates the global instance of ThermalManager. All hooks and components work internally with this ThermalManager object.

Hooks

Core structure

useThermalManager - get the global instance of ThermalManager
useThermalRegistry( registryId, options ) - create or get an instance of ThermalRegistry

Properties that might be manipulated from React

useThermalManagerPaletteDrive - color palette
useThermalRegistryOpacityDrive - IR / VISIBLE ratio
useThermalRegistryRangeDrive - adjustable temperature range
useThermalGroupCursorPositionDrive - cursor synchronisation

States of which React needs to know

useThermalRegistryHistogramState exposes the current histogram
useThermalRegistryLoadingState exposes current loading state
useThermalRegistryMinmaxState exposes the min & max temperature of a registry
useThermalGroupMinmaxState exposes the min & max temperature of a group

Listing

useThermalRegistryGroupsState groups in a registry
useThermalGroupInstancesState file instances in a group

Components

Thermal imaging does not mean just 'displaying thermal images'. This functionality is handled by @labir/core. A fully equipped app needs other functionality - which needs to be implemented in components.

Thermal imaging components

Components specific to thermal imaging are provided by this package:

ThermalFile - displays a thermal file
Histogram - displays a histogram
ThermalRange - displays adjustable temperature scale

Styling of these component is framework agnostic, using inline CSS.

Hooks for buttons, dropdowns and modals

Standard UI components such as buttons, modals & dropdowns need to be implemented in a particular (S)CSS framework. For this purpose, here are hooks that handles the underlying functionality:

Inputs controlling IR / VISIBLE ratio: useOpacityInput
Dropdowns or button lists controlling the palette: useThermalManagerPaletteDrive
Inputs controlling histogram resolution: useHistogramResolutionInput
Button for automatic temperature range: useRangeButtonAuto
Button for reseting temperature range: useRangeButtonFull
Drop in components: useThermalDropin

This package contains core bindings to the @labir/core package.
