Barcode Scanner

+ +

Beta License: AGPL-3 OCA/barcode-interface Translate me on Weblate Try me on Runboat

+

This module is the base framework of the Barcode suite: a fast, +full-screen scanning application shell for Odoo that other modules +extend.

+

It ships no business logic of its own. Instead it exposes the building +blocks feature modules plug into, the same way Odoo widgets +self-register:

+
    +
  • a full-screen client action and a lightweight in-app router;
    • +
  • registries for screens, scan handlers and home-screen menu tiles +(barcode_screens, barcode_scan_handlers, +barcode_menu_tiles);
    • +
  • the barcode input service (hardware/keyboard wedge), audio/vibration +feedback, an ORM/API wrapper and shared hooks.
    • +
+

Install a feature module on top — such as barcode_stock — to get +actual warehouse operations.

+

Table of contents

+ +
+

Usage

+

barcode_scanner is a framework and is not useful on its own: install +a feature module such as barcode_stock to get actual operations.

+

To build your own feature module, register your pieces into the +framework registries — no change to the base module is required.

+

Register a screen:

+
+import {barcodeScreens} from "@barcode_scanner/js/registries";
+
+barcodeScreens.add("my_screen", {component: MyScreen});
+
+

Register a scan handler (tried in sequence order; the first that +returns a truthy value consumes the scan):

+
+import {barcodeScanHandlers} from "@barcode_scanner/js/registries";
+
+barcodeScanHandlers.add("my_handler", {
+    async handle(barcode, parsed, {api, navigate, notify}) {
+        // return true when handled
+    },
+}, {sequence: 50});
+
+

Register a home-screen tile:

+
+import {barcodeMenuTiles} from "@barcode_scanner/js/registries";
+
+barcodeMenuTiles.add("my_tile", {
+    label: "My Screen",
+    icon: "fa-cube",
+    action: ({navigate}) => navigate("my_screen"),
+}, {sequence: 50});
+
+

Register a barcode parser (tried in sequence order before the +built-in EAN13 one; return null to let the next parser try):

+
+import {barcodeParsers} from "@barcode_scanner/js/registries";
+
+barcodeParsers.add("my_symbology", (barcode) => {
+    // return {type: "...", value: "<product code>", ...} or null
+}, {sequence: 20});
+
+

Register a startup task, for data your module needs before the first +scan (barcode_gs1 reads its nomenclature this way). Tasks are +awaited when the app opens; one that fails is logged and skipped:

+
+import {barcodeStartupTasks} from "@barcode_scanner/js/registries";
+
+barcodeStartupTasks.add("my_config", (env) => loadMyConfig(env.services.orm));
+
+
+
+
