AJV

AJV is a js schema validation tool. This example shows how to use it from squint. It also demonstrates importing a library that is formatted as a CommonJS module.

nmp i
npx squint run ajv.cljs

CommonJS Import Notes

(ns ajv (:require ["ajv-formats" :refer [addFormats]]))

;; [squint] Running ajv.cljs
;; file:///Users/zcpowers/Documents/Projects/squint/examples/ajv/ajv.mjs:3
;; import { addFormats } from 'ajv-formats';
;;          ^^^^^^^^^^
;; SyntaxError: Named export 'addFormats' not found. The requested module 'ajv-formats' is a CommonJS module, which may not support all module.exports as named exports.
;; CommonJS modules can always be imported via the default export, for example using:
;;
;; import pkg from 'ajv-formats';
;; const { addFormats } = pkg;

;; correct. note the `$default
(ns ajv (:require ["ajv-formats$default" :as addFormats))
