attodom

attodom

yet another experimental small DOM component library, <2kb

• Why • API • License

Why

• experimenting on different APIs to find the minimal helpers required for
  • dynamic nodes, elements and lists
  • one way data flow from root component to child nodes

Features

• multiple dynamic lists within the same parent
• svg and namespace support
• ability to inject a document API for server use and/or testing (e.g. jsdom)
• no virtual DOM, all operations are done on actual nodes
• less than 1kb gzip, no dependencies
• Designed for phones and/or older browsers:
  • very low memory requirement
  • no transpilation required

Limitations

• strictly DOM element creation and manipulations (no router, no store)

API

Elements and Nodes (hyperscript)

• el(tagName [, attributes[, updater [,children]]] ): HTMLElement
• svg(tagName [, attributes[, updater [,children]]] ): SVGElement
• text(content [, properties[, updater]]] ): TextNode

where attributes: {name: value} updater: function(Node, [*], [*], [*]):Node children: {number|string|Node|Array<children>}

Helper Function

update: function(Node, [*], [*], [*]):Node Updates a node with the provided updater defined on creation

updateChildren: function(ParentNode, [*], [*], [*]):ParentNode Updates all children nodes of a parenta node with the provided updater defined on creation

Lists

• list(nodeFactory [, getKey]): CommentNode

where nodeFactory: function([*], [*], [*]): Node getKey: function([*], [number], [Array]): string

list creates a Comment Node that will be followed by a variable number of Nodes upon update with an array. A list can't contain another list

Server use

Document can be injected as follow:

const core = require('attodom/core')
core.document = myDocumentObject
