Failed to load latest commit information. Add GitHub Sponsors funding method. Oct 22, May 22, Update FileSaver. Nov 19, Sep 26, May 14, Closes A lot has changed since the last version of Modernizr. There no longer is a single, base modernizr. Instead, just head over to the Download page as you could have previously, and select the features you want to use in your project.

This way we can provide the smallest file possible, which means a faster website for you. You may notice that in addition to the Build output, where you have been able to download custom builds one at a time for years now - there are two new options. Since 3. That means that you can quickly create multiple builds of Modernizr for different projects, without even having to open a new browser tab.

Once you have npm installed , you can install the Modernizr command line tool by running. Now you are ready to get your start making your custom build! You can download the configuration file from the build menu under "Command Line Config". Note that you will need to give the command line config the file path to the configuration you downloaded from the site. In the above example, we are running the modernizr command from the same folder that we downloaded the modernizr-config.

If you do not want to manually run your build from the command line every time you update your site, you also have the option to download a Grunt task to do it for you. This configuration file can be used with grunt-modernizr to automatically build your custom version. Just add it to your Gruntfile , and you are off to the races. Note that you will need to update the provided configuration file with paths to the devFile and outputFile. More documentation is available for grunt-modernizr here.

In addition to the available options and feature detects, there are a handful of additional configuration options. This means adding the class for each feature when it is supported, and adding it with a no- prefix when it is not e. This makes it super simple to add features in via progressive enhancement! Say you include Modernizr's detection for CSS gradients. Now that you know those two states, you can write CSS to cover both cases.

If one of Modernizr's class names clashes with one of your preexisting classes, you have the option to add a classPrefix inside of your config. Consider the hidden detect, which adds a.

If you wanted to use that specific detection, you could use the following as your configuration. This lets hide certain elements that should only be exposed in environments that execute JavaScript. If you want to disable this change, you can set enableJSClass to false in your config. If you are using a classPrefix , such as supports- , then you must include that prefix on your html element.

Finally, if you do not want Modernizr to add any of it's classes, you can set enableClasses to false. This does not effect the. Modernizr keeps track of the results of all of it's feature detections via the Modernizr object. File Upload using React! Next File uploading in Node. Recommended Articles. Article Contributed By :. Easy Normal Medium Hard Expert. Writing code in comment? Please use ide. VS Code maintains a debug session while the program is running, and pressing the Stop button terminates the program.

Tip : The Run action is always available, but not all debugger extensions support 'Run'. In this case, 'Run' will be the same as 'Debug'. Breakpoints can be toggled by clicking on the editor margin or using F9 on the current line. The Reapply All Breakpoints command sets all breakpoints again to their original location.

This is helpful if your debug environment is "lazy" and "misplaces" breakpoints in source code that has not yet been executed. Optionally, breakpoints can be shown in the editor's overview ruler by enabling the setting debug.

A Logpoint is a variant of a breakpoint that does not "break" into the debugger but instead logs a message to the console. Logpoints are especially useful for injecting logging while debugging production servers that cannot be paused or stopped.

A Logpoint is represented by a "diamond" shaped icon. The Python and Java extensions, for example, support Logpoints. Variable values can be modified with the Set Value action from the variable's context menu. Additionally, you can use the Copy Value action to copy the variable's value, or Copy as Expression action to copy an expression to access the variable. There are many launch.

VS Code makes commonly used paths and other values available as variables and supports variable substitution inside strings in launch. This means that you do not have to use absolute paths in debug configurations.

You can see a full list of predefined variables in the Variables Reference or by invoking IntelliSense inside the launch. To do so, put a platform-specific literal into the launch. Below is an example that passes "args" to the program differently on Windows:. Valid operating properties are "windows" for Windows, "linux" for Linux, and "osx" for macOS. Properties defined in an operating system specific scope override properties defined in the global scope.

Please note that the type property cannot be placed inside a platform-specific section, because type indirectly determines the platform in remote debugging scenarios, and that would result in a cyclic dependency.

I got the following console output when I ran this script: node. Does this code close the file properly when the script ends or would it lose data? This depends upon the req url type if you are requesting https you must use https otherwise it will throw error. EthanKeiley why do you say that it isn't closed properly?

By default createWriteStream will set autoClose to true and readable. Show 14 more comments. Don't forget to handle errors! The following code is based on Augusto Roman's answer. But we don't check the result if cb cb err. Vince Yuan Vince Yuan VinceYuan the callback is confusing me.

What would I place as the cb argument? Abdul Sounds like you are very new to node. Take a look at this tutorial: tutorialspoint.

Abdul maybe it would be good if you share with the rest of the class what you have figured out?
