formfeed

The Formfeed CLI: templates as files, offline validation and hot-reload preview with the same engine the API uses, true renders through the API, push and pull against a workspace.

npx formfeed init my-templates && cd my-templates
npx formfeed dev hello                      # http://localhost:4400, no account needed
npx formfeed login --api-key ff_test_…      # a key from the API keys page (template:write for push)
npx formfeed templates pull                 # workspace templates into templates/<slug>/
npx formfeed validate                       # diagnostics; exit 1 on errors
npx formfeed templates push --publish --message "Add EPC QR code"
npx formfeed render invoice-de --data default --out invoice.pdf

Layout of a template folder (template.json carries name, kind and engine):

templates/invoice-de/
  template.json  template.html  style.css  head.html  header.html  footer.html
  settings.json  schema.json  i18n.json  data/default.json  data/*.json

templates/offer/                            a Word template (template.pptx for PowerPoint)
  template.json  template.docx  settings.json  schema.json  i18n.json  data/*.json

Word and PowerPoint templates are filled on your machine: render --output docx writes the filled document, render --output pdf converts it through the API (Starter plan and above). QR codes, barcodes and SVG pictures in them are drawn by @resvg/resvg-js, an optional dependency; without it they are left out with a warning.

More commands:

npx formfeed pdf convert report.xlsx        # any Word, Excel, PowerPoint, OpenDocument or RTF file to PDF
npx formfeed import apitemplate --all --key "$APITEMPLATE_API_KEY" --source-region de
npx formfeed files push                     # the files/ folder into the workspace file library
npx formfeed brand pull                     # the brand kit for local previews
npx formfeed partials pull                  # shared partials into partials/
npx formfeed workspaces delete <id> --yes   # needs the workspace:delete scope

Configuration precedence: flags, then FORMFEED_API_KEY / FORMFEED_BASE_URL / FORMFEED_WORKSPACE / FORMFEED_REGION, then formfeed.json, then the user config (~/.config/formfeed/config.json, %APPDATA%\formfeed\config.json). Exit codes: 0 ok, 1 validation, 2 usage, 3 auth, 4 network or API, 5 quota.

Coding agents learn these commands from the skills in formfeed-dev/skills, a plugin for Claude Code and a package for any agent that reads Agent Skills: https://docs.formfeed.dev/devkit/coding-agents
