Atom Turbo Javascript Save

Commands and snippets for faster Javascript and Typescript with the Atom Editor

Project README

turbo-javascript

A collection of commands and ES6-ready snippets for optimizing Javascript and Typescript development productivity.

Commands

Use the following keymaps to speed up your development. You can quickly terminate lines with semicolons or manipulate blocks of code with ease.

End Line CTRL-;

Terminates the current line with a semicolon.

End Line with a comma CTRL-,

Terminates the current line with a comma (great for object literals).

End New Line CTRL-ENTER

Terminates the current line with a colon or semicolon, followed with a new line. A comma is inserted when the cursor is inside an object literal, otherwise a semicolon is inserted.

Easy Blocks CTRL-B

Creates a statement block { ... } with the selected text placed inside and properly indented. If the selection is already wrapped with a block, the block is removed and its content is unindented.

Snippets

Snippets are optimized to be short and easy to remember. Some snippets are "chainable" and render differently when preceded by a ".".

For example, .fe renders a chain-friendly version of the "forEach" snippet, while fe renders a full code block.
