🤹 Usage
Installation
yarn add iguazu iguazu-holocron
# or
npm install --save iguazu iguazu-holocron
Usage within your module
Use queryModule
if you would like to render a Module as soon as its bundle is loaded.
import React from 'react';
import { connectAsync } from 'iguazu';
import { queryModule } from 'iguazu-holocron';
const MyModule = ({ loadStatus, MySubModule }) => {
if (loadStatus.all === 'loading') {
return <Loading />;
}
return (
<div>
<MySubModule />
</div>
);
};
const loadDataAsProps = ({ store: { dispatch } }) => ({
MySubModule: () => dispatch(queryModule('my-sub-module')),
});
export default connectAsync({ loadDataAsProps })(MyModule);
Use queryModuleWithData
if you would like to wait until a Module's Iguazu data dependencies are loaded to render. Any props that are necessary for the Module to decide what data to load should be passed as the second argument.
import React from 'react';
import { compose } from 'redux';
import { connectAsync } from 'iguazu';
import { queryModuleWithData } from 'iguazu-holocron';
import { connect } from 'react-redux';
const MyModule = ({ loadStatus, MySubModuleWithData, subModuleProp }) => {
if (loadStatus.all === 'loading') {
return <Loading />;
}
return (
<div>
<MySubModuleWithData subModuleProp={subModuleProp} />
</div>
);
};
const getSubModuleProps = (state, ownProps) => { /* return props to be passed to submodule */ };
const loadDataAsProps = ({ store: { dispatch, getState }, ownProps }) => ({
MySubModuleWithData: () => dispatch(queryModuleWithData('my-sub-module-with-data', getSubModuleProps(getState(), ownProps))),
});
const mapStateToProps = (state, ownProps) => ({
subModuleProps: getSubModuleProps(state, ownProps),
});
export default compose(
connectAsync({ loadDataAsProps }),
connect(mapStateToProps)
)(MyModule);
Sometimes a Module may fail to load. If that is the case the data returned from Iguazu Holocron will be an instance of EmptyModule
. The helper function anyAreEmpty
will tell you if any of the Modules you pass to it are an empty Module.
import React from 'react';
import { connectAsync } from 'iguazu';
import { queryModule, anyAreEmpty } from 'iguazu-holocron';
const MyModule = ({ loadStatus, SubModuleA, SubModuleB }) => {
if (loadStatus.all === 'loading') {
return <Loading />;
}
const pageFailedToLoad = anyAreEmpty(SubModuleA, SubModuleB);
return pageFailedToLoad
? <LoadError />
: (
<div>
<SubModuleA />
<SubModuleB />
</div>
);
};
const loadDataAsProps = ({ store: { dispatch } }) => ({
SubModuleA: () => dispatch(queryModule('sub-module-a')),
SubModuleB: () => dispatch(queryModule('sub-module-b')),
});
export default connectAsync({ loadDataAsProps })(MyModule);
🎛️ API
queryModule
An Iguazu adapter for loading a Holocron module.
Arguments
| name | type | required | value |
|---|---|---|---|
| moduleName
| String
| true
| The name of the Holocron module to load |
Usage
import { connectAsync } from 'iguazu';
import { queryModule } from 'iguazu-holocron';
const MyModule = ({ MyOtherModule }) => (
<>
{/* some jsx */}
<MyOtherModule />
</>
)
function loadDataAsProps({ store }) {
return {
MyOtherModule: () => store.dispatch(queryModule('my-module')),
};
}
export default connectAsync({ loadDataAsProps })(MyModule);
queryModuleWithData
An Iguazu adapter for loading a Holocron module and its data (from the loaded module's own
loadDataAsProps
).
Arguments
| name | type | required | value |
|---|---|---|---|
| moduleName
| String
| true
| The name of the Holocron module to load |
| moduleProps
| Object
| true
| Initial props to pass the module when loading |
Usage
import { connectAsync } from 'iguazu';
import { queryModuleWithData } from 'iguazu-holocron';
const MyModule = ({ MyOtherModule, someData }) => (
<>
{/* some jsx */}
<MyOtherModule someData={someData} />
</>
)
function loadDataAsProps({ store, ownProps }) {
return {
MyOtherModule: () => store.dispatch(
queryModuleWithData('my-module', { someData: ownProps.someData })
),
};
}
export default connectAsync({ loadDataAsProps })(MyModule);
isEmpty
isEmpty
checks to see if the module queried has been loaded or if the module received in props is
still the default empty component.
Arguments
| name | type | required | value |
|---|---|---|---|
| module
| Function
| true
| A module that has been loaded by one of the above Iguazu adapters |
Usage
import { connectAsync } from 'iguazu';
import { queryModule, isEmpty } from 'iguazu-holocron';
const MyModule = ({ MyOtherModule }) => (
<>
{/* some jsx */}
{isEmpty(MyOtherModule) ? <Spinner /> : <MyOtherModule />}
</>
)
function loadDataAsProps({ store }) {
return {
MyOtherModule: () => store.dispatch(queryModule('my-module')),
};
}
export default connectAsync({ loadDataAsProps })(MyModule);
anyAreEmpty
anyAreEmpty
taks n
arguments, all of which are Holocron modules loaded with one of the above
Iguazu adapters. It is used to check if any modules in the argument list are still the default empty
module.
Arguments
| name | type | required | value |
|---|---|---|---|
| module
| Function
| true
| A module that has been loaded by one of the above Iguazu adapters |
Usage
import { connectAsync } from 'iguazu';
import { queryModule, anyAreEmpty } from 'iguazu-holocron';
const MyModule = ({ MyOtherModule, ThirdModule }) => (
<>
{/* some jsx */}
{ anyAreEmpty(MyOtherModule, ThirdModule) ?
<Spinner /> :
<MyOtherModule><ThirdModule/></MyOtherModule>
}
</>
)
function loadDataAsProps({ store }) {
return {
MyOtherModule: () => store.dispatch(queryModule('my-module')),
ThirdModule: () => store.dispatch(queryModule('third-module')),
};
}
export default connectAsync({ loadDataAsProps })(MyModule);
configureIguazuSSR
configureIguazuSSR
is a helper for loading data on the server via Iguazu. It does not need to be
called directly, but needs to be attached to the module as the static loadModuleData
along with
loadDataAsProps
.
loadModuleData
is a module lifecycle hook used by Holocron for data fetching during server side rendering.
Usage
import { connectAsync } from 'iguazu';
import { queryModule } from 'iguazu-holocron';
const MyModule = ({ data }) => <p>{`Data: ${data}`}</p>)
function loadDataAsProps({ store }) {
return {
data: () => store.dispatch(queryData()),
};
}
MyModule.loadDataAsProps = loadDataAsProps;
MyModule.loadModuleData = configureIguazuSSR;
export default connectAsync({ loadDataAsProps })(MyModule);

📜 Available Scripts
To test out any changes that you've made locally, run yarn pack
then install this within your application.
The scripts below are available to run and use:
yarn babel
This deletes the current JS files within the lib
directory and compiles the ECMAScript 6 code within the src
file to a version of ECMAScript that can run in current browsers using Babel afterwards it copies them to the lib folder.
yarn build
This runs yarn babel
yarn prepublish
This runs yarn build
