This is a VS Code extension which inserts 'use strict' statement to all JavaScript files (*.js, *.ts) across your workspace.

Putting a 'use strict' statement to the begining of a JavaScript file enables ECMAScript 5's strict mode. Read this article from MDN if you don't know what it is.

This extension is supposed to be used in Node.js projects only. For front end projects if you use transpilers like Webpack or Rollup, they add the 'use strict' statement to the output automatically.

• Scan the content of file so that it won't do anything if the file already contains the 'use strict' statement
• Configurations (single quote or double quote, use a semicolon or not) for different coding styles

Open command palette (Mac ⇧⌘P, Windows Ctrl+Shift+P), search for Insert "use strict" in workspace, press Enter.

This extension contributes the following settings:

• insertUseStrict.useDoubleQuote: Use single/double quote. (default: false)
• insertUseStrict.addTrailingSemicolon: Add semicolon at the end of the statement. (default: false)
• insertUseStrict.autoSave: Save the documents automatically after editing (default: true)
• insertUseStrict.globPattern: The glob pattern of files to apply changes. (default: **/*.{js,ts})
• insertUseStrict.autoApplyToNewFiles: If set to true, apply changes when new files are created. (default: true)

• Add globPattern config
• Add autoApplyToNewFiles config

• Add logo

• Initial Release
