Hoodie-plugin-global-share NPM

Hoodie Global Share Plugin

Make selected objects publically accessible via hoodie.global store methods.

Installation

hoodie install global-share

Usage

The Global Share Plugin extends all promises returned by hoodie.store methods with two additional functions: publish and unpublish.

// publish all my todos
hoodie.store.findAll('task').publish()

// unpublish specific note
hoodie.store.find('note', 'abc1234').unpublish()

All objects marked as public are accessible (read-only) via the hoodie.global API

// list all public tasks
hoodie.global.findAll('task').then(showAllPublicTasks)

// update list of tasks on change
hoodie.global.on('task:change', handleTaskChange)

Full Frontend API

add / remove own objects from the public global store

// publish / unpublish can be called on all promises
// return by any hoodie.store method.
promise = hoodie.store.add(type, attributes).publish()
promise = hoodie.store.find(type, id).publish()
promise = hoodie.store.findOrAdd(type, id, attributes).publish()
promise = hoodie.store.findAll(/* type */).publish()
promise = hoodie.store.update(type, id, changedAttributes).publish()
promise = hoodie.store.updateAll(/* type, */ changedAttributes).publish()
promise = hoodie.store.remove(type, id).publish()
promise = hoodie.store.removeAll(/* type */).publish()

// it works the same on scoped stores
promise = hoodie.store(type).find(id).unpublish()
promise = hoodie.store(type, id).update(changedAttributes).publish()

// publish / unpublish return own promises that only resolve
// if the objects were published successfully on the server
promise.then(handlePublishSuccess, handleStoreOrPublishError);

access objects from / listen to changes in the public global store

// hoodie.global has all read-only methods from hoodie.store,
// with the same footprint
promise = hoodie.global.find(type, id)
promise = hoodie.global.findAll(/* type */)

// you can listen on changes as well
hoodie.global.on('add', handleNewObject)
hoodie.global.on('task:change', handleChangedTask)
hoodie.global.on('task:123:remove', handleTask123Removed)

How it works internally

The plugin's worker creates a new database hoodie-plugin-global-share that all objects from all user databases that are marked as public are replicated to.

Calling .publish() on a store method in the frontend adds a $public: true flag to the respecitve objects, that is used by the filtered replications from user databases → hoodie-plugin-global-share database.

Calling .unpublish() uses the hoodie.task API internally to start globalshareunpublish task with object types/IDs to be unpublished. The task gets picked up by the worker which then removes all objects with the passed types/IDs from the hoodie-plugin-global-share database.
