If you use "upward-optional", be aware that it will walk up theĭirectory structure all the way to the filesystem root, and it is always "root" is the default mode because it avoids the risk that Babel willĪccidentally load a that is entirely outside of the current Looking for a directory containing a įile, and falls back to "root" if a "upward-optional" - Walk upward from the "root" directory,."upward" - Walks upward from the "root" directory, lookingįor a directory containing a įile, and throws an error if a."root" - Passes the "root" value through as unchanged.In older Babel 7 versions, only is supported. The different modes define different ways thatīabel can process the "root" value to get the final project root. This option, combined with the "root" value, defines how BabelĬhooses its project root.

Note: This option is not on by default because the majority of users won't need Would be a chain of multiple transform passes, along the lines of ast īabel's default is to generate a string and a sourcemap, but in someĬontexts it can be useful to get the AST itself. Use ast: true to get the AST directly in order to avoid doing unnecessary work. In some contexts where multiple calls to BabelĪre being made, it can be helpful to disable code generation and instead code īabel's default return value includes code and map properties with the Used as the default value for Babel's sourceFileName option, and usedĪs part of generation of filenames for the AMD / UMD / SystemJS module transforms. If this option is omitted, Babel will behave as if babelrc: false has been set.ĭefault: path.relative(opts.cwd, opts.filename) (if "filename" was passed) babelrc files are loaded relative to the file being compiled.
