Interactions are visual changes of the screen which occur when users act on user interface elements. In other words, interactions are the behaviors of the user interface. For instance, when a user click a button, an image switches to another, or when a user drags an edge, the viewport expands. Those are interactions. Users are doing their jobs with a computer through various interactions generally. To implement interactions on a web page, programming with JavaScript is needed. However, it is hard to manage JavaScript for many designers. Therefore, making well-designed web interactions is difficult in general. IxEdit solves this problem. -

JSDefender
PreEmptive
Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities. -

Support for the most popular JavaScript testing frameworks. Support for instrumenting subprocesses, using the nyc command-line interface. Adding coverage to your mocha tests could not be easier. Now, simply place the command nyc in front of your existing test command. nyc's instrument command can be used to instrument source files outside of the context of your unit tests. nyc is able to show you all Node processes that are spawned when running a test script under it. By default, nyc uses Istanbul's text reporter. However, you may specify an alternative reporter.Starting Price: Free -
