#BABEL PLUGIN TRANSFORM RUNTIME CODE#

You can find community maintained presets on npm Plugins determines plugins and polyfills you need based on your supported environments A preset is simply an array of plugins that make it easier to run a whole a set of transforms without specifying each one manually. For example: the es2015-arrow-functions transform specifically changes arrow functions into regular functions.

#BABEL PLUGIN TRANSFORM RUNTIME CODE#

The transformer used in Babel are the independent pieces of code that transform specific things.

is a standalone package used to generate errors that print the source code and point to error locations.Īfter Babel 6, the default transforms were removed if you don't specify any plugins/presets, Babel will just return the original source code.

is a set of pre-made functions that are used in some Babel plugins.

is a helper function that allows constructing AST nodes from a string presentation of the code this eliminates the tedium of using for building AST nodes.

is a way to automatically compile files with Babel on the fly by binding to Node.js require.

is similar to the polyfill except that it doesn't modify the global scope and is to be used with (usually in library/plugin code).

is used to validate, build and change AST nodes.

Other is the CLI tool that runs and helps with outputting to a directory, a file, stdout and more (also includes cli). Input string -> parser -> AST -> transformer -> AST -> -> output stringĬheck out the babel-handbook for more information on this. These all use to traverse through the AST.The parser: The transformer: All the plugins/presets.The compiler can be broken down into 3 parts: See the monorepo design doc for reasoning.Ĭore Packages is the Babel compiler itself it exposes the ansform method, where transformedCode = transform(src).code.
