Editable JSON for Meteor - Click here for demo app

Quick Start

meteor add babrahams:editable-json

In a template, write:

{{> editableJSON}}

This will turn the current data context into an editable block of JSON.

After editing (which won't have any effect on the data context or make any database writes), you can retrieve the modified JSON, as a javascript object, with:

EditableJSON.retrieve();

If you do want immediate updates to a certain document in a certain collection to be persisted in mongo, just write:

{{> editableJSON collection="posts" document=post}}

where the helper post is returning a document from the posts collection. Or write document=this if the surrounding data context is already a document from the posts collection.

More advanced use

If you want to explicity pass a javascript object to the widget instead of using the surrounding data context:

{{> editableJSON json=myJSObjectFromAHelper}}

If you want several widgets operating on the screen at once:

{{> editableJSON json=JSObj1 store="custom1"}}
{{> editableJSON json=JSObj2 store="custom2"}}

And to retrieve these:

var JSObj1 = EditableJSON.retrieve("custom1");
var JSObj2 = EditableJSON.retrieve("custom2");

You can add callbacks (that fire on client only).

After updates:

EditableJSON.afterUpdate(function (store, action, JSONbefore, documentsUpdated) {
  // Overwrite this function in client side js to create a callback after every edit	
  // `this` in the callback function context is the document or the json AFTER the update
  // `store` is the name of the data store as defined above (it will be `undefined` if not defined)
  // `store` will be the collection name, if you're using the package to do direct updates to Mongo documents
  // `action` is a Mongo update operator -- either `{$set: {field: value}}` or `{$unset: {field: 1}}`
}[, store]);

If a newly added field appears to be unpublished:

EditableJSON.onUnpublishedFieldAdded(function (collection, field, value) {
  // Overwrite this function in client side js to alert user that they
  // may not be seeing what they expect when adding new fields
  // due to restrictions on the fields being published
});

If you include the optional parameter store the callback will only fire when the specified store (or collection) is updated, otherwise it will fire on any update to any store/collection.
