Package Exports

udomdiff
udomdiff/cjs/index.js
udomdiff/esm/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (udomdiff) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

An essential diffing algorithm for µhtml.

Signature

futureNodes = udomdiff(
  parentNode,           // where changes happen
  [...currentNodes],    // Array of current items/nodes
  [...futureNodes],     // Array of future items/nodes (returned)
  get(node, toDoWhat),  // a callback to retrieve the node
  before                // the anchored node to insertBefore
);

What is `get` and how does it work?

You can find all info from domdiff, as it's exactly the same concept:

get(node, 1) to retrieve the node that's being appended
get(node, 0) to get the node to use for an insertBefore operation
get(node, -0) to get the node to use for an insertAfter operation
get(node, -1) to retrieve the node that's being removed

If you don't care about any of those second arguments values, const get = o => o; is a valid get too.
