Release Changes

Client side JavaScript code optimization which may reduce CPU and memory consumption in the client browser page if there is a continues delivery of UI updates from the server. However, the difference may be negligible.

Note: This release doesn't contain any new features.

Release Changes

Code optimization for performance improvement.

Release Changes

New features

• Implemented jsonMapFactory and jsonListFactory in JsonParser.

Major improvements

Major improvements to AbstractHtml

• Thread-safety and performance improvements.
• Now, for appendChildren, prependChildren, insertAfter, insertBefore, replaceWith & addInnerHtmls methods, there is only a single implementation. If the given tags by these methods already exist in the browser page, the server will not send its entire tag data; instead, it will send only the wff id, and using its wff id the tags will be moved in the browser page for the ui changes. It will save a lot of data transfer in many scenarios,
  eg: There is table in the browser page and it contains a large number of rows. The rows are sorted and added again to the TBody tag without removing it from the browser page, in such case we can see a significant performance improvement as it doesn't transfer the whole tags data to the UI.

Minor improvements

• Code optimization in SharedTagContent.

Release Changes

Major bug fixes

A major thread-safety bug fix in SharedTagContent reported in #97.

The bug is it throws NullPointerException while calling setContent/detach method if async update is enabled. To workaround this issue, disable async update by setAsyncUpdate method. By default, it is disabled.

Major improvements

JVM related improvements to prevent CPU overheating in a special multi-threading scenario.

Release Changes

New Features

Support for basic JSON parser. This is the most efficient way to parse JSON text in the world.

Usage:

To parse json object string

JsonMapNode jsonMap = JsonMap.parse("""
             {
             "key" : "value",
             "key1" : "value1"
             }
             """);
 // To get value
 String key1Value = jsonMap.getValueAsString("key1");

 // Prints value
 System.out.println("key1Value = " + key1Value); // key1Value = value1

 String jsonString = jsonMap.toJsonString();
 // Prints json string
 System.out.println("jsonString = " + jsonString); // jsonString = {"key1":"value1","key":"value"}
 

To parse json array string

JsonListNode jsonList = JsonList.parse("[1, 4, 0, 1]");

//To get the value from an index
int intValueAt1 = jsonList.getValueAsInteger(1);
System.out.println("intValueAt1 = " + intValueAt1); // intValueAt1 = 4

//Prints the json string
System.out.println("toJsonString = " + jsonList.toJsonString()); // toJsonString = [1,4,0,1]

To parse json string with different config

JsonParser jsonParser = JsonParser.newBuilder()
                 .jsonObjectType(JsonObjectType.JSON_MAP)
                 .jsonArrayType(JsonArrayType.JSON_LIST)
                 .jsonNumberArrayUniformValueType(false)
                 .jsonNumberValueTypeForObject(JsonNumberValueType.BIG_DECIMAL)
                 .jsonNumberValueTypeForArray(JsonNumberValueType.BIG_DECIMAL)
                 .jsonStringValueTypeForObject(JsonStringValueType.STRING)
                 .jsonStringValueTypeForArray(JsonStringValueType.STRING)
                 .jsonBooleanValueTypeForObject(JsonBooleanValueType.BOOLEAN)
                 .jsonBooleanValueTypeForArray(JsonBooleanValueType.BOOLEAN)
                 .jsonNullValueTypeForObject(JsonNullValueType.NULL)
                 .jsonNullValueTypeForArray(JsonNullValueType.NULL)
                 .validateEscapeSequence(true).build();

JsonMap jsonObject = jsonParser.parseJsonObject("""
            {
            "key1" : "val1",
            "key2" : "val2"
            }""") instanceof JsonMap jsonMap ? jsonMap : null;


System.out.println(jsonObject.toJsonString()); //Prints {"key1":"val1","key2":"val2"}
 

Improvements

• Implemented getValueAsWffBMObject & getValueAsWffBMArray methods in WffBMArray & WffBMObject.
• Optimized code for performance improvement.

Release Changes

Major improvements

Performance improvements

Reduced the size of payload sending from the server to the client by implementing version 3 of Wff BM Bytes tag data compression algo. This should deliver data faster than before.

Major bug fixes

Major bug fix related to uri navigation

Bug: set uri from the server side using browserPage.setURI then click on back button on browser, it doesn't invoke the whenURI event. This bug is fixed now.

The workaround to fix this issue till wffweb-12.0.2 is to call wffGlobal.getAndUpdateLocation(); inside the wffGlobalListeners.onSetURI function implementation in the project.

Features

More finder methods findOneAttributeByFilter, findAttributesByFilter etc.. in TagRepository.

Implemented more feature methods in WffBMObject & WffBMArray to get values in different datatypes.
They are:

• getValueAsBigDecimal
• getValueAsBigInteger
• getValueAsInteger
• getValueAsLong
• getValueAsDouble
• getValueAsFloat
• getValueAsBoolean
• getValueAsString

Implemented overloading put(... methods in WffBMObject.
They are:

• put(String key, Number value)
• put(String key, Boolean value)
• put(String key, WffBMObject value)
• put(String key, WffBMArray value)
• put(String key, WffBMByteArray value)

Implemented other put...(... methods in WffBMObject.
They are:

• putNull(String key)
• putUndefined(String key)
• putRegex(String key, String regex)
• putString(String key, String string)
• putFunction(String key, String function)

Implemented method similar in WffBMObject and WffBMArray to check if two objects contents are equal.

Implemented toStream method in WffBMNumberArray.

Improvements

In AbstractHtml, validating the appending/prepending children only if the debug mode is turned on by WffConfiguration.setDebugMode(true). If it is turned off it will save some memory and CPU consumption so it is turned off by default.

Java code improvements

Annotated serialVersionUID with @Serial in appropriate places.

Test cases

Test cases are added for all new features.

Migration changes

No code changes required to migrate from wffweb 12.0.2 to 12.0.3.

Release Changes

New features

Added readState method in SharedTagContent.
Added utility methods in URIUtil class for building url query string.
Added more finder methods in TagRepository class.

Improvements

Internal code syntax performance improvements in TagRepository.
Micro optimization for performance improvement in TagRepository.
Javadoc needful improvements.

Migration changes

No code changes required to upgrade from 12.0.1 to 12.0.2.

Release Changes

• Improved reliability of sending client ping message.
• The internal thread locking mechanism is optimized with a better alternative implementation.
• Minor bug fix in AbstractHtml (related to add child method).
• Upgraded code syntax in appropriate places.
• Minor optimization in BrowserPageContext.
• Session handling improvements in BrowserPageContext.
• Thread-safety improvements in SharedTagContent to avoid unwanted async behavior.
• Upgraded test scope dependencies.

New feature methods

New methods in AbstractHtml

Support for ParentGainedListener and ParentLostListener in tag class. ParentGainedListener will be invoked when a tag gains a new parent and ParentLostListener will be invoked when a tag loses its parent. Needful methods such as addParentGainedListener, removeParentGainedListener, addParentLostListener, removeParentLostListener etc.. will be available in AbstractHtml so that they can be accessed by any tag class. Eg: Refer removing server method using ParentLostListener.

New methods in PayloadProcessor

Implemented is isValid methods in PayloadProcessor which will be useful in websocket config. Refer the sample project websocket config for its usage.

Made some methods public in BrowserPageContext

• Made BrowserPageContext.runAutoClean public to allow to run a manual cleanup.

Release Changes

It's ready for production use.

There is no major bug found in wffweb-12.0.0-beta.12 so wffweb-12.0.0 is the same copy of it. The only change done in wffweb-12.0.0 is some minor improvements in javadoc comment.
