If you need to scale the image dynamically (i.e. Note that image sources required this way include size (width, height) info for the Image. In order for this to work, the image name in require has to be known statically. Images can be distributed via npm packages.The bundler knows the image dimensions, no need to duplicate it in the code.Adding and changing images doesn't require app recompilation, you can refresh the simulator as you normally do.Only the images that are actually used will be packaged into your app.you don't have to worry about name collisions. Images live in the same folder as your JavaScript code.On Windows, you might need to restart the bundler if you add new images to your project. textContent attribute as it is a Safe Sink and will automatically HTML Entity Encode.

URIError Thrown if encodedURI contains a not followed by two hexadecimal digits, or if the escape sequence does not encode a valid UTF-8 character. But if you have a part of a URL, use encodeURIComponent. If you have a complete URL, use encodeURI. Let params = encodeURIComponent('mango & pineapple') When accepting query parameters that may have reserved characters. When building a URL from query string parameters. When accepting an input that may have spaces. Examples const url = ''Ĭonsole.log(encodeURIComponent(url)) //https%3A%2F%2Fconst paramComponent = '?q=search'Ĭonsole.log(encodeURIComponent(paramComponent)) //"%3Fq%3Dsearch"Ĭonsole.log(url + encodeURIComponent(paramComponent)) // ![]() ![]() Here's a handy table of the difference in encoding of characters Which characters are encoded?ĮncodeURI() will not encode: will not encode: ~!*()' What is the difference between encodeURI and encodeURIComponent?ĮncodeURI and encodeURIComponent are used to encode Uniform Resource Identifiers (URIs) by replacing certain characters by one, two, three or four escape sequences representing the UTF-8 encoding of the character.ĮncodeURIComponent should be used to encode a URI Component - a string that is supposed to be part of a URL.ĮncodeURI should be used to encode a URI or an existing URL. Need to accept query string parameters in order to make GET requests.User has submitted values in a form that may be in a string format and need to be passed in, such as URL fields.Special characters such as &, space, ! when entered in a url need to be escaped, otherwise they may cause unpredictable situations. This means that we need to encode these characters when passing into a URL. Reserved characters that do not belong to this set must be encoded. Covering popular subjects like HTML, CSS, JavaScript, Python, SQL, Java, and many, many more. URLs can only have certain characters from the standard 128 character ASCII set. W3Schools offers free online tutorials, references and exercises in all the major languages of the web. All URLs are URIs, but not all URIs are URLs. A URL specifies a resource and how it can be accessed (the protocol). URI stands for Uniform Resource Identifier.Īnything that uniquely identifies a resource is its URI, such as id, name, or ISBN number. What is a URI and how is it different from a URL? In this article, I will demystify the difference between encodeURI and encodeURIComponent. And you might be confused which one to use and when.
