If set to "inline", a comment with a sourceMappingURL directive is added to the bottom of the returned code. If truthy, adds a map property to returned output. NOTE: This overrides the comment option when used. Called as shouldPrintComment(commentContents). Called as resolveModuleSource(source, filename).Īn optional callback that controls whether a comment should be output or not.
( NOTE: This will not retain the columns) This will lead to wacky code but is handy for scenarios where you can't use source maps. List of presets (a set of plugins) to load and use. When attempting to compile a non-matching file it's returned verbatim.Īn object containing the options to be passed down to the babel parser, babylon Can also be an array of arrays containing paths to explicitly match. Optional prefix for the AMD module formatter that will be prepend to the filename on module definitions.Ī glob, regex, or mixed array of both, matching paths to only compile. If truthy, insert an explicit id for modules. Should the output be minified (not printing last semicolons in blocks, printing literal string values instead of escaped ones, stripping () from new when safe) ignore is disregarded if only is specified.Ī source map object that the output source map will be based on. If falsy value is returned then the generated module id is used. Specify a custom callback to generate a module id with.
If BABEL_ENV isn't set then NODE_ENV will be used, if it's not set then it defaults to "development"Īn object containing the options to be passed down to the babel code generator, babel-generator ansform(code, options) // => which will use those options when the environment variable BABEL_ENV is set to "production". Returning an object with the generated code, var babel = require("babel-core") Īll transformations will use your local configuration files (.babelrc or in package.json).
