Standard JavaScript Snippets for Atom

A collection of ES6 standardjs code style snippets for faster JavaScript development in Atom Editor.

Installation

apm install standardjs-snippets

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.

Commands

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

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 followed with a new line. A comma is inserted when the cursor is inside an object literal.

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.
