GWT Storage

A future-proof port of the com.google.gwt.storage.Storage GWT module, with no dependency on gwt-user (besides the Java Runtime Emulation), to prepare for GWT 3 / J2Cl.

Migrating from com.google.gwt.storage.Storage

1. Add the dependency to your build.

   For Maven:

   <dependency>
       <groupId>org.gwtproject.storage</groupId>
       <artifactId>gwt-storage</artifactId>
       <version>HEAD-SNAPSHOT</version>
   </dependency>

   For Gradle:

   implementation("org.gwtproject.storage:gwt-storage:HEAD-SNAPSHOT")

2. Update your GWT module to use

   <inherits name="org.gwtproject.storage.Storage" />

3. Change the imports in your Java source files:

   import org.gwtproject.storage.client.*;

Instructions

To build gwt-storage:

• run mvn clean verify

on the parent directory. This will build the artifact and run tests against the JVM, J2CL, and GWT2.

System Requirements

GWT Storage requires GWT 2.9.0 or newer!

Dependencies

GWT Storage does not depend on any other module.??????????

Roadmap

1. Migrate the current gwt-2.8.2 code and remove incompatible dependencies (DONE)
2. Remove dependency on JavaScriptObject (DONE)
3. Remove all jsni constructions (DONE)
4. Add support for Native Events (pending issue from Gwt2)
5. Optionally support receiving notifications of current session modifications
6. Add support for automated testing multiple browser sessions from Gwt Unit Test

Known issues

Issues inherited from gwt2-storage

• Native events are not yet correctly supported, they are emulated.
• Testing multiple browser sessions in a single Gwt Unit Test is not supported by Gwt. Is it?

Issues resulting from migration

• It's unknown what mechanism should be used to substitute GWT.reportUncaughtException. See method org.gwtproject.storage.client.StorageImpl.handleStorageEvent
