This is the base Javascript library that interfaces with the [Graffiti server](https://github.com/graffiti-garden/server).
We recommend not using this vanilla library itself but instead using framework plugins that are built on top of it like the [Graffiti plugin for Vue.JS](https://github.com/graffiti-garden/graffiti-x-vue).
-Example usage:
-
-```javascript
-import Graffiti from "https://graffiti-garden.github.io/graffiti-x-js/graffiti.js"
-
-// You can initialize a connection to the graffiti server
-const graffiti = Graffiti()
-await graffiti.initialize()
-
-// You can subscribe to queries
-const queryID = await graffiti.subscribe({
- type: 'post',
- content: { $type: 'string' }
- }
- // With an arbitrary update callback
- (obj) => console.log(`An object has been created: {obj}`),
- // and remove callback
- (obj) => console.log(`An object with id {obj._id} by user {obj._by} has been removed.`)
-)
-
-// And then unsubscribe to those queries
-await graffiti.unsubscribe(queryID)
-
-// You can toggle logging in and out
-graffiti.toggleLogIn()
-
-// When you are logged in you can reference your user ID
-console.log(graffiti.myID)
-
-// And when you are logged in you can
-// create objects,
-const myCoolPost = {
- type: 'post',
- content: 'hello world'
-}
-// ("completing" an object annotates
-// it with your user ID and a random
-// object ID, required by the server)
-graffiti.complete(myCoolPost)
-await graffiti.update(myCoolPost, {})
-
-// replace objects,
-myCoolPost.content += '!!!'
-await graffiti.update(myCoolPost, {})
-
-// and remove objects.
-await graffiti.remove(myCoolPost)
-
-// The second argument in the update
-// function is a query. If the object you
-// try to add does not match the query
-// it will be rejected. This prevents
-// you from accidentally creating data
-// that gets "lost".
-const query = { type: 'post' }
-const myPost = { type: 'post' }
-const myNotPost = { type: 'notpost' }
-graffiti.complete(myNotPost)
-// This works
-await graffiti.update(myPost, query)
-// But this won't work!
-await graffiti.update(myNotPost, query)
-```
+If you create a [local Graffiti instance](https://github.com/graffiti-garden/server#local-usage) and a local webserver in this directory (*e.g.* `python3 -m http.server`) and navigate to `test.html` (*e.g.* [http://localhost:8000/test.html](http://localhost:8000/test.html)) you should be able to log in and test each of the Graffiti primitives: `subscribe`, `unsubscribe`, `update`, `remove`. These primitives will be robust to spamming and network interruptions.
