    broccoli-node-info

    This is a low-level package used to communicate with Broccoli nodes (that is, plugin instances). It provides a thin wrapper around node.__broccoliGetInfo__(), normalizing different versions of the node API to the newest version.

    This package is mainly used by the Broccoli Builder class, but it can also be used for inspecting nodes for testing, wrapping, diagnostics, or similar purposes. If you are tempted to call node.__broccoliGetInfo__() or access private variables on broccoli-plugin instances, such as node._name or node._inputNodes, then use this package instead!

    For background on the Broccoli node API, see docs/node-api.md.

    Usage

    var broccoliNodeInfo = require('broccoli-node-info');
    
    node = new SomeBroccoliPlugin();
    
    var nodeInfo = broccoliNodeInfo.getNodeInfo(node);
    // Now we can use nodeInfo.name, nodeInfo.annotation, etc.

    getNodeInfo(node)

    This function calls node.__broccoliGetInfo__(broccoliNodeInfo.features).

    For node objects conforming to the most recent node API, it simply returns the resulting nodeInfo object.

    For node object conforming to an older version of the node API, it provides compatibility code to normalize the nodeInfo object.

    As a result, regardless of the API version used by the node object, we obtain a nodeInfo object conforming to the current specification in docs/node-api.md

    This function throws a broccoliNodeInfo.InvalidNodeError when called with

    • a plain string node (while still supported by the Broccoli Builder, they are deprecated in favor of broccoli-source),
    • a node using the old .read/.rebuild API (see docs/broccoli-1-0-plugin-api.md), or
    • some other object that isn't a node.

    InvalidNodeError

    Error subclass, potentially thrown by getNodeInfo().

    features

    A hash of all supported feature flags. This hash acts like a version number for the node API. In the current version, its value is

    {
      persistentOutputFlag: true,
      sourceDirectories: true
    }
