À propos de cette extension
SUMMARY:

Lint and format JavaScript, Python, and HubL directly inside your automation tool's built-in development window, backed by Ruff and Biome.

DETAILS:

Clean up and check your code right inside automation workflows without needing to bounce over to VS Code or any other editor.

Supported environments:
  • Zapier (using Code by Zapier steps for Python and JavaScript)
  • n8n (for JavaScript and Python code blocks on n8n.cloud, n8n.io, or self-hosted instances)
  • Pipedream (JavaScript and Python code actions)
  • Make (JavaScript modules)
  • HubSpot Data Hub (custom Python and JavaScript code blocks)
  • HubSpot Design Manager / CMS (HubL templates featuring HTML/CSS blocks alongside module.js)

Workflow:
  • Launch any code workspace on a compatible service.
  • Trigger formatting using any of these three methods:
  • Click the browser extension toolbar icon for codefmt and choose "format code" to see all lint errors directly in the menu.
  • Use the right-click context menu and choose "Format with codefmt" (pure formatting) or "Fix with codefmt" (formatting, safe lint repairs, and import sorting).
  • Hit Ctrl+Shift+F (or the Mac equivalent) while focused inside the editor.
  • The tool processes your text and updates the editor automatically.
  • A popup notification displays the top 3 lint warnings (prioritizing errors), showing the exact line number, rule violated, and message. Hover to pin the alert, or click/press Esc to dismiss it.

Core Capabilities:
  • Context-aware formatting tailored to each platform's specific execution structure (including handling of global variables, return habits, line lengths, and async envelopes)
  • Automatic detection of Python, JavaScript, and HubL (including nested HTML, CSS, and JS contexts within HubSpot CMS)
  • Rapid lint analysis driven by Ruff for Python and oxlint for JavaScript—both high-performance Rust utilities
  • JS and TS formatting powered by Biome, delivering Prettier-compatible styling
  • Python linting and formatting handled entirely by Ruff
  • HubL support via a bespoke template formatter designed for HubSpot CMS
  • Right-click "Fix with codefmt" action that cleans imports and resolves safe Biome linter warnings in a single sweep
  • Deep customization options: target print width, semicolon usage, quote types, trailing commas, bracket spacing, arrow function parentheses, JSX quote preferences, object property quoting, same-line brackets, and import organization
  • One-click settings sync via codefmt.dev. Manage preferences in your browser, apply them in the extension. Profiles are maintained independently per platform.
  • Global shortcut (Ctrl+Shift+F) active whenever your cursor is inside an editor field
  • Self-hosted n8n support: type your instance URL in the extension panel, and Firefox will prompt for targeted permission. Exact domain matching ensures that removing an entry immediately revokes its access.
  • Light and dark themes that inherit your operating system preference automatically
  • A dynamic tab badge displays "fmt" on active domains so you always know the tool is running
  • If Firefox permission is disabled or lost, the extension flags this with a "!" badge and provides an instant one-click remedy in the popup, eliminating guesswork
  • Fully compatible with CodeMirror (versions 5 and 6) and Monaco editors used across all supported platforms
  • Maximum file payload of 50 KB per formatting request
  • 30-second timeout threshold equipped with automatic retries for temporary connection drops

Data Practices & Privacy:
  • Zero tracking, telemetry, cookies, or user accounts required
  • Formatting rules and preferences live exclusively in your local browser storage
  • Submitting code transmits it via HTTPS to codefmt.dev/api/format, where it is handled entirely in RAM and sent back cleaned up. No logs, database records, or third-party sharing occur.
  • Operation is strictly restricted to the listed automation domains (plus codefmt.dev solely for preference synchronization)
  • Complete policy statement available at: https://codefmt.dev/privacy

Safety Measures:
  • Built on Manifest V3 using minimal required permissions (scripting, storage, activeTab, contextMenus)
  • Only approved domains can initiate formatting requests
  • Incoming internal messages undergo strict origin and sender validation prior to any network activity
  • Strict Content Security Policy enforced across all extension windows
  • Zero remote code loading. Every script is bundled locally as plain, readable JavaScript with no obfuscation or build steps.

Under the Hood:
  • Biome (biomejs.dev): Rust-engineered, Prettier-aligned layout engine for JavaScript and TypeScript
  • oxlint (oxc.rs): Swift JavaScript checker sharing a familiar rule catalog
  • Ruff (astral.sh/ruff): High-speed Python linting and formatting suite relied on by major software projects
