title: Using ES2016 for Writing Plugins

Please understand how the PluginMechanism works since this is all about writing a plugin using Babel to compile the output that will be included in the final TiddlyWiki (for example [[TiddlyWiki on Node.js]]).

It is recommended to use develop toolkit managed by community. For example,

!! Compiling the Output
Another benefit of using such a "Meta-Framework" is that you can easily maintain your configuration, you will find it difficult to upgrade those config files after several months.
!!! Compiling the Output
Pick a folder to store the ES2015 JavaScript and a folder to output the TiddlyWiki ready JavaScript. In this example I will use `src` and `lib` respectively. With Babel installed and working I can compile all the JavaScript in the `src` folder to the `lib` folder by running this command:

<<.warning "Babel will //not// copy over non-JavaScript files. It is up to the developer to include all the supporting files themselves. Babel only converts the ~JavaScript files (ending in `.js`) from the `src` folder to the `lib` folder.">>

It is important to understand that in ES2016 the ''default'' export is not supported in TiddlyWiki. This is mostly because the core code expects specific properties to be attached to the `exports` variable. Bable's `export` conversion plays well with this //except// with the default export.

ES2015 comes with some features that are part of the JavaScript core objects. These are not supported by all browsers.

title: Bags and Recipes
type: text/vnd.tiddlywiki
The bags and recipes model is a reference architecture for how tiddlers can be shared between multiple wikis. It was first introduced by TiddlyWeb in 2008.
The principles of bags and recipes can be simply stated:
# Tiddlers are stored in named "bags"
# Bags have access controls that determines which users can read or write to them
# Recipes are named lists of bags, ordered from lowest priority to highest
# The tiddlers within a recipe are accumulated in turn from each bag in the recipe in order of increasing priority. Thus, if there are multiple tiddlers with the same title in different bags then the one from the highest priority bag will be used as the recipe tiddler
# Wikis are composed by splicing the tiddlers from the corresponding recipe into the standard TW5 HTML template
A very simple example of the recipe/bag model might be for a single user who maintains the following bags:
* ''recipes'' - tiddlers related to cooking recipes
* ''work'' - tiddlers related to work
* ''app'' - common tiddlers for customising TiddlyWiki
Those bags would be used with the following recipes:
* ''recipes'' --> recipes, app - wiki for working with recipes, with common custom components
* ''work'' --> work, app - wiki for working with work, with common custom components
* ''app'' --> app - wiki for maintaining custom components
All of this will work dynamically, so changes to the app bag will instantly ripple into the affected hosted wikis.
A more complex example might be for a teacher working with a group of students:
* ''student-{name}'' bag for each students work
* ''teacher-course'' bag for the coursework, editable by the teacher
* ''teacher-tools'' bag for custom tools used by the teacher
Those bags would be exposed through the following hosted wikis:
* ''student-{name}'' hosted wiki for each students work, including the coursework material
* ''teacher-course'' hosted wiki for the coursework, editable by the teacher
* ''teacher'' hosted wiki for the teacher, bringing together all the bags, giving them an overview of all the students work

title: TiddlyWebAdaptor
type: text/vnd.tiddlywiki
TiddlyWebAdaptor is a component of [[TiddlyWiki on Node.js]]. It provides the means to synchronise changes to tiddlers from the browser to a server, and from the server to the browser. It can be found in the plugin [[$:/plugins/tiddlywiki/tiddlyweb]].
TiddlyWebAdaptor was designed to be compatible both with TiddlyWeb and with TiddlyWiki's own built-in server mechanism. The [[Bags and Recipes]] model is fully supported by [[TiddlyWeb]], but TiddlyWiki's built-in server only supports a simplified model with a single bag and a single recipe.
