@stamp/init-property
Replaces properties which reference stamps with objects created from the stamps
If your StampA would have, say, property foo
which references a StampB, then the property will be replaced with the StampB instance. The parameter for the StampB(arg)
will be taken form the foo
property of the StampA argument.
You might find it useful for better Dependency Injection pattern.
Usage
const StampA = compose({
properties: {
foo: StampB
}
})
.compose(InitProperty);
// StampB will receive initializer argument `{bar: 'baz'}`
StampA({foo: {bar: 'baz'}});
Example
import InitProperty from '@stamp/init-property';
import Oauth2 from './stamps/oauth2';
const GravatarClient = compose(InitProperty, {
properties: {
auth: Oauth2 // the 'auth' property is expected to be passed to the stamp
},
methods: {
getProfilePicture() {
return fetch('gravatar.com', {
headers: {
Authorization: this.auth.getHttpHeader() // accessing this.auth
}
});
}
}
});
const gravatarClient = GravatarClient({
auth: { // Passing the data for the 'Oauth2' stamp
client_id: '1', client_secret: '2', grant_type: 'simple'
}
});
gravatarClient.getProfilePicture().then(stream => fs.writeFileSync(stream));
