UI Plugin API

The PluginApi object is a global object in the window object.

PluginApi is considered experimental and is subject to change without notice. This documentation covers only the plugin-specific API. It does not necessarily cover the core UI API. Information on these methods should be referenced in the UI source code.

An example using various aspects of PluginApi may be found in the source code under pkg/plugin/examples/react-component.

Properties

React

An instance of the React library.

ReactDOM

An instance of the ReactDOM library.

GQL

This namespace contains the generated graphql client interface. This is a low-level interface. In many cases, StashService should be used instead.

libraries

libraries provides access to the following UI libraries: - ReactRouterDOM - Bootstrap - Apollo - Intl - FontAwesomeRegular - FontAwesomeSolid - Mousetrap - MousetrapPause

register

This namespace contains methods used to register page routes and components.

PluginApi.register.route

Registers a route in the React Router.

Parameter	Type	Description
path	string	The path to register. This should generally use the /plugin/ prefix.
component	React.FC	A React function component that will be rendered when the route is loaded.

Returns void.

PluginApi.register.component

Registers a component to be used by plugins. The component will be available in the components namespace.

Parameter	Type	Description
name	string	The name of the component to register. This should be unique and should ideally be prefixed with plugin-.
component	React.FC	A React function component.

Returns void.

components

This namespace contains all of the components available to plugins. These include a selection of core components and components registered using PluginApi.register.component.

utils

This namespace provides access to the NavUtils and StashService namespaces. It also provides access to the loadComponents method.

PluginApi.utils.loadComponents

Due to code splitting, some components may not be loaded and available when a plugin page is rendered. loadComponents loads all of the components that a plugin page may require.

In general, PluginApi.hooks.useLoadComponents hook should be used instead.

Parameter	Type	Description
components	Promise[]	The list of components to load. These values should come from the PluginApi.loadableComponents namespace.

Returns a Promise<void> that resolves when all of the components have been loaded.

hooks

This namespace provides access to the following core utility hooks: - useSpriteInfo - useToast

It also provides plugin-specific hooks.

PluginApi.hooks.useLoadComponents

This is a hook used to load components, using the PluginApi.utils.loadComponents method.

Parameter	Type	Description
components	Promise[]	The list of components to load. These values should come from the PluginApi.loadableComponents namespace.

Returns a boolean which will be true if the components are loading.

loadableComponents

This namespace contains all of the components that may need to be loaded using the loadComponents method. Components are added to this namespace as needed. Please make a development request if a required component is not in this namespace.

patch

This namespace provides methods to patch components to change their behaviour.

PluginApi.patch.before

Registers a before function. A before function is called prior to calling a component's render function. It accepts the same parameters as the component's render function, and is expected to return a list of new arguments that will be passed to the render.

Parameter	Type	Description
component	string	The name of the component to patch.
fn	Function	The before function. It accepts the same arguments as the component render function and is expected to return a list of arguments to pass to the render function.

Returns void.

PluginApi.patch.instead

Registers a replacement function for a component. The provided function will be called with the arguments passed to the original render function, plus the next render function as the last argument. Replacement functions will be called in the order that they are registered. If a replacement function does not call the next render function then the following replacement functions will not be called or applied.

Parameter	Type	Description
component	string	The name of the component to patch.
fn	Function	The replacement function. It accepts the same arguments as the original render function, plus the next render function, and is expected to return the replacement component.

Returns void.

PluginApi.patch.after

Registers an after function. An after function is called after the render function of the component. It accepts the arguments passed to the original render function, plus the result of the original render function. It is expected to return the rendered component.

Parameter	Type	Description
component	string	The name of the component to patch.
fn	Function	The after function. It accepts the same arguments as the original render function, plus the result of the original render function, and is expected to return the rendered component.

Returns void.
