Familiarity with javascript is assumed. In all of the following examples, the source coffeeScript is provided on the left, and the direct compilation into javascript is on the right. Many of the examples can be run (where it makes sense) by pressing the button on the right. The coffeeScript on the left is editable, and the javascript will update as you edit. First, the basics: CoffeeScript uses significant whitespace to delimit blocks of code. You dont need to use semicolons ; to terminate expressions, ending the line will do just as well (although semicolons can still be used to fit multiple expressions onto a single line). Instead of using curly braces to surround blocks of code in functions, if-statements, switch, and try/catch, use indentation. You dont need to use parentheses to invoke a function if youre passing arguments.

Babelrc file (or other equivalent) in place, you can use coffee -transpile to pipe coffeeScripts output through Babel using the options youve saved. If youre using CoffeeScript via the node api, where you call mpile with a string to be compiled and an options object, the transpile key of the options object should be the babel options: mpile(code, transpile: presets: 'env you can also transpile coffeeScripts output without. This lets you use transpilers other than Babel, and it gives you greater control over the process. There are many great task runners for setting up javascript build chains, such as Gulp, webpack, grunt and Broccoli. Polyfills Note that transpiling doesnt automatically supply polyfills for your code. CoffeeScript itself will output dexOf if you use the in operator, or destructuring or spread/rest syntax; and nd if you use a bound ( ) method in a class. Both are supported in Internet Explorer 9 and all more recent browsers, but you will need to supply polyfills if you need to support Internet Explorer 8 or below and are using features that would cause these methods to be output. Youll also need to supply polyfills if your own code uses these methods or another method added in recent versions of javascript. One polyfill option is babel-polyfill, though there are many other strategies. Language reference This reference is structured so that it can be read summary from top to bottom, if you like. Later sections use ideas and syntax previously introduced.

To use either, babel-core must be installed in your project: npm install -save-dev babel-core Or if youre running the coffee command outside of a project folder, using a globally-installed coffeescript module, babel-core needs to be installed globally: npm install -global babel-core by default, babel doesnt. You need to provide it with a configuration so that it knows what. One way to do this is by creating. Babelrc file in the folder containing the files youre compiling, or in any parent folder up the path above those files. (Babel supports other ways, too.) A minimal. Babelrc file would be just "presets "env". This implies that you have installed babel-preset-env : npm install -save-dev babel-preset-env Or -global for non-project-based usage see babels website to learn about presets and plugins and the multitude of options you have. Another preset you might need is transform-react-jsx if youre using jsx revelation with react (jsx can also be used with other frameworks). Once you have babel-core and babel-preset-env (or other presets or plugins) installed, and.

Anspile, object : if set, this must be an object with the options to pass to babel. Transpilation CoffeeScript 2 generates javascript that uses the latest, modern syntax. The runtime or browsers where you want your code to run might not support all of that syntax. In write that case, we want to convert modern javascript into older javascript that will run in older versions of Node or older browsers; for example, a obj into a obj. This is done via transpilers like babel, bublé or Traceur Compiler. Quickstart From the root of your project: npm install -save-dev babel-core babel-preset-env echo ' "presets "env" '. Babelrc coffee -compile -transpile -inline-map ffee transpiling with the coffeeScript compiler to make things easy, coffeeScript has built-in support for the popular Babel transpiler. You can use it via the -transpile command-line option or the transpile node api option.

Require './ffee you must first register CoffeeScript as an extension: require 'coffeescript/register' App require './app' The. Coffee extension is optional If you want to use the compilers api, for example to make an app that compiles strings of CoffeeScript on the fly, you can require the full module: CoffeeScript require 'coffeescript' eval mpile 'console. Log "Mmmmm, i could really go for some Math. Pi the compile method has the signature compile(code, options) where code is a string of CoffeeScript code, and the optional options is an object with some or all of the following properties: urceMap, boolean: if true, a source map will be generated; and instead. LineMap, boolean: if true, output the source map as a base64-encoded string in a comment at the bottom. Lename, string: the filename to use for the source map. It can include a path (relative or absolute). Re, boolean: if true, output without the top-level function safety wrapper. Header, boolean: if true, output the generated by coffeeScript header.

Use this flag to forward options directly to node. To pass multiple flags, use -nodejs multiple times. tokens Instead of parsing the coffeeScript, just lex it, and print out the token stream. Used for debugging the compiler. n, -nodes Instead of compiling the coffeeScript, just lex and parse it, and print out the parse tree. Examples: Compile a directory tree.

Coffee files in src into a parallel tree. Js files in lib: coffee -compile -output lib/ src/ Watch a file for changes, and recompile it every time essay the file is saved: coffee -watch -compile ffee concatenate a list of files into a single script: coffee -join project. Coffee print out the compiled js from a one-liner: coffee -bpe "alert i for i.10" All together now, watch and recompile an entire project as you work on it: coffee -o lib/ -cw src/ Start the coffeeScript repl (Ctrl-D to exit, Ctrl-Vfor multi-line. Js If youd like to use node. Js CommonJS to require coffeeScript files,.

p, -print Instead of writing out the javascript as a file, print it directly to stdout. s, -stdio pipe in CoffeeScript to stdin and get back javascript over stdout. Good for use with processes written in other languages. An example: cat src/ffee coffee -sc -l, -literate parses the code as Literate coffeeScript. You only need to specify this when passing in code directly over stdio, or using some sort of extension-less file name.

e, -eval Compile and print a little snippet of CoffeeScript directly from the command line. For example: coffee -e "console. Log num for num.1" -r, -require module require the given module before starting the repl or evaluating the code given with the -eval flag. b, -bare compile the javascript without the top-level function safety wrapper. no-header Suppress the generated by coffeeScript header. nodejs The node executable has some useful options you can set, such as -debug, -debug-brk, -max-stack-size, and -expose-gc.

m, -map Generate source maps alongside the compiled javascript plan files. Adds sourceMappingurl directives to the javascript as well. m, -inline-map Just like -map, but include the source map directly in the compiled javascript files, rather than in a separate file. i, -interactive launch an interactive coffeeScript session to try short snippets. Identical to calling coffee with no arguments. o, -output dir write out all compiled javascript files into the specified directory. Use in conjunction with -compile or -watch. w, -watch Watch files for changes, rerunning the specified command when any file is updated.

Usage command Line Once installed, you should have access to the coffee command, which can execute scripts, compile. Js, and provide an interactive repl. The coffee command takes the following options: Option Description -c, -compile compile. Coffee script into. Js javascript file of the same name. t, -transpile pipe the coffeeScript compilers output through Babel before saving or running the generated javascript. Requires babel-core to be bean installed, and options to pass to babel. Babelrc file or a package. Json with a babel key in the path of the file or folder to be compiled.

in the browser (see try coffeeScript ). To install, first make sure you have a working copy of the latest stable version of Node. You can then install CoffeeScript globally with npm : npm install -global coffeescript This will make the coffee and cake commands available globally. If you are using CoffeeScript in a project, you should install it locally for that project so that the version of CoffeeScript is tracked as one of your projects dependencies. Within that projects folder: npm install -save-dev coffeescript The coffee and cake commands will first look in the current folder to see if CoffeeScript is installed locally, and use that version. This allows different versions of CoffeeScript to be installed globally and locally. If you plan to use the -transpile option (see transpilation ) you will need to also install babel-core either globally or locally, depending on whether you are running a globally or locally installed version of CoffeeScript.

The biggest change in CoffeeScript essay 2 is that now the coffeeScript compiler produces modern javascript syntax (ES6, or ES2015 and later). A coffeeScript becomes a js, a coffeeScript class becomes a js class and. Major new features in CoffeeScript 2 include async functions and, jSX. You can read more in the announcement. There are very few breaking changes from CoffeeScript.x to 2 ; we hope the upgrade process is smooth for most projects. Compatibility, most modern javascript features that CoffeeScript supports can run natively in Node.6, meaning that Node can run CoffeeScripts output without any further processing required. Here are some notable exceptions: This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to een for full details. You can run the tests in your browser to see what your browser supports. It is your responsibility to ensure that your runtime supports the modern features you use; or that you transpile your code.
