Inverse 0.4.0 released

Inverse 0.4.0 is out. @sweberdev/inverse and @sweberdev/inverse-react are on npm under the MIT licence, and the Pro packages are updated on GitHub Packages for licence holders. Nothing breaks: 0.3.0 code keeps working as it is.

What is in 0.4.0

• Duplicate protection. People click twice, reload the confirmation page or retry on a slow connection. With dedupe: { windowMs } the handler answers an identical declaration with the first result, so you store one record and send one receipt. E-mail addresses are compared case-insensitively. It is off by default and works in createInverseHandler, createNodeHandler and the script-tag forms that post to them.

import { createInverseHandler } from "@sweberdev/inverse";

export const POST = createInverseHandler({
  company,
  onDeclaration,
  sendReceipt,
  dedupe: { windowMs: 10 * 60_000 },
  rateLimit: { max: 10 },
});

Inverse Pro 0.4.0

• Team digest. teamDigest(records) builds one e-mail a week with everything that needs doing: refunds that are due after a withdrawal (14 days after receipt), contracts that end in the next two weeks, cancellations whose end date was not sent yet, and all declarations received in the period. Run it from a cron job with the records from your ledger. dueItems() returns the same list as data for your back office.
• Reports for clients. The audit's HTML report now has a print stylesheet, so Print → Save as PDF gives an A4 report to attach to an offer. inverse-audit --csv overview.csv writes one row per site with the verdict and both button targets, for agencies that track all client sites in a spreadsheet.

Inverse Pro is available on the package page, from CHF 19 a month.
