:zap: A collection of JavaScript snippets for Atom, Standard Style
A collection of ES6 standardjs code style snippets for faster JavaScript development in Atom Editor.
Yes!, no semicolons:
apm install standardjs-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.

Use the following keymaps to speed up your development. You can quickly terminate lines with colons or manipulate blocks of code with ease.
CTRL-,
Terminates the current line with a comma (great for object literals).
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.
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.
