License comments use up a lot of space, especially when using many small
libraries with large license blocks. With this addition, you can extract
all license comments to a separate file and remove them from the bundle
files. A small banner points to the file containing all license
information such that the user can find it if needed.
We add a new option extractComments to the UglifyJsPlugin.
It can be omitted, then the behavior does not change, or it can be:
- true: All comments that normally would be preserved by the comments
option will be moved to a separate file. If the original file is
named foo.js, then the comments will be stored to foo.js.LICENSE
- regular expression (given as RegExp or string) or a function
(astNode, comment) -> boolean: All comments that match the given
expression (resp. are evaluated to true by the function) will be
extracted to the separate file. The comments option specifies
whether the comment will be preserved, i.e. it is possible to
preserve some comments (e.g. annotations) while extracting others or
even preserving comments that have been extracted.
- an object consisting of the following keys, all optional:
- condition: regular expression or function (see previous point)
- file: The file where the extracted comments will be stored. Can be
either a string (filename) or function (string) -> string which
will be given the original filename. Default is to append the
suffix .LICENSE to the original filename.
- banner: The banner text that points to the extracted file and will
be added on top of the original file. will be added to the
original file. Can be false (no banner), a string, or a function
(string) -> string that will be called with the filename where
extracted comments have been stored. Will be wrapped into comment.
Default: /*! For license information please see foo.js.LICENSE */
* refactor(eslint): Added no-unsed-vars, env specific .eslintrc's for buildin & hot
* This change allows for buildin to now be part of the lint test by addition of an extra .eslintrc file which extends existing but sets es6 to false
* Turned on no-unused-vars for eslint, and then removed all warnings from turning that feature on
* Was getting notified of errors in "quote" property in eslintrc, so changed to correct value from error to 2.
* beautify
* swap invalid eslint config val
