A highly configurable file resolver
searchPath, and various options, return a resolved path.
Works on the same principle as node's
require.resolve method does, however, it is
far more configurable and does not assume any particular structure. (i.e: you have to
give it the structure to search).
npm install resolveit
var resolveIt =path;trypath = resolveIt;catch errorconsole;console;
Will return a string (or an array of strings if
options.findAll is true). Will
Error if the
search can not be found (unless
options.silent is true).
Takes the following arguments:
searcha string, the name, or subpath, you want to find
basedira string, or an array of strings, of the directories you want to start searching from.
optionsan object with one or more of the following properties:
basedira string, or an array of strings, as above. (Replaces the
prefixa string, or an array of strings, of sub-directory paths to append to the
basedirpath (i.e: 'node_modules').
indexa string, or an array of strings, possible directory index base-names to try (i.e: 'index', or ['index', 'main']).
extensiona string, or an array of strings, possible file extensions to try (i.e: 'js').
packagesan array of strings, or an object with package file names as property names and functions as values (see below).
findAlla boolean, return all found paths. Default
directoriesa boolean, match on directories. Default
silenta boolean, silently fail (don't throw an exception). Default
basedir defaults to the directory of the calling method's file path, or
process.cwd() if that can not be determined.
packages option allows you specify which file names should be treated as
If given an
Array of package names, the default is to treat the file as a JSON file
and return the
main property joined with the found file's directory path.
// Default package reader behaviorpath = resolveIt;
If given an
Object with properties as package names and their values as functions,
the function will be passed the file path and is expected to return the actual path
to find the file. If a false-like value is returned, it moves on to the next
// Custom package readerpath = resolveIt;
Using an error stack, try to determine the calling directory. If passed the optional startPath parameter, use that to determine where to start looking in the stack trace.
path, as a string, and explodes it into an array of ascending directories.
resolveIt; // => [ 'a/b/c', 'a/b', 'a', '.' ]
Does the underlying work of building all possible search paths calling
with each path. If the callback returns true, then the search will stop, otherwise
it will continue on to the next path.
options are the same as
resolveIt.sync's arguments, with the exception that
presumed to be defined as a string, or an array of strings.
resolveIt;// would generate the following results:// a/b/d/e// a/b/d/e.js// a/b/d/e/index// a/b/d/e/index.js// a/b/d/node_modules/e// a/b/d/node_modules/e.js// a/b/d/node_modules/e/index// a/b/d/node_modules/e/index.js// a/d/e// a/d/e.js// a/d/e/index// a/d/e/index.js// a/d/node_modules/e// a/d/node_modules/e.js// a/d/node_modules/e/index// a/d/node_modules/e/index.js// d/e// d/e.js// d/e/index// d/e/index.js// d/node_modules/e// d/node_modules/e.js// d/node_modules/e/index// d/node_modules/e/index.js
