+# ObjectBox TS/JS (based on IndexedDB)
+
+This is a very basic ObjectBox implementation for JavaScript/TypeScript, based on IndexedDB instead of the native objectbox-c API.
+
+### Build and copy to objectbox-dart
+
+The following code builds TypeScript files into `build` folder, uses `webpack` to create a single JS,
+copies the JS (and sourcemap) to `../objectbox/lib/`, and generates dart binding code in `../objectbox/lib/src/web/`.
+```shell
+npm run build:main
+npm run install
+npm run generate:dart
+```
+
+Or run a single action to do it all:
+```shell
+npm run all:dart
+```
+
+### Notes and useful links about the compilation/integration:
+
+* modules are not supported, we need to compile to a single JS file (using `webpack`)
+* example: https://github.com/google/chartjs.dart/
+* example: https://github.com/matanlurey/dart_js_interop
+* modules issue: https://github.com/dart-lang/sdk/issues/25059
+
+### IndexedDB resources
