You can fetch the file as a blob and provide it the same way, there will be no request that leads into CORS issues. Template <a :href=”item.url” v-text=”item.label” @click.prevent=”downloadItem(item)” /> Vue methods: { downloadItem ({ url, label }) { Axios.get(url, { responseType: ‘blob’ }) .then(response => { const blob = new Blob([response.data], { type: ‘application/pdf’ … Read more
The error message says it all. You declare a string type of csv variable. You then assign string | ArrayBuffer type (of reader.result) to the string type, you just assigned. You cannot. You only can assign string to string. So, if you 100% sure that reader.result contains string you could assert this: const csv: string … Read more
Concepts ArrayBuffers represents a byte-array in physical memory. An ArrayBuffer is the actual storage for the bytes but is rarely used directly – in fact, you don’t have access to read content of ArrayBuffer directly and can only pass a reference for it. They are on the other hand used for binary data transfers between … Read more
From axios docs: // `responseType` indicates the type of data that the server will respond with // options are: ‘arraybuffer’, ‘document’, ‘json’, ‘text’, ‘stream’ // browser only: ‘blob’ responseType: ‘json’, // default ‘blob’ is a “browser only” option. So from node.js, when you set responseType: “blob”, “json”will actually be used, which I guess fallbacks to … Read more
The current behaviour, is determined by the endianness of the underlying hardware. As almost all desktop computers are x86, this means little-endian. Most ARM OSes use little-endian mode (ARM processors are bi-endian and thus can operate in either). The reason why this is somewhat sad is the fact that it means almost nobody will test … Read more
Using TextEncoder and TextDecoder var uint8array = new TextEncoder(“utf-8”).encode(“Plain Text”); var string = new TextDecoder().decode(uint8array); console.log(uint8array ,string )
You can use FileReader to read the Blob as an ArrayBuffer. Here’s a short example: var arrayBuffer; var fileReader = new FileReader(); fileReader.onload = function(event) { arrayBuffer = event.target.result; }; fileReader.readAsArrayBuffer(blob); Here’s a longer example: // ArrayBuffer -> Blob var uint8Array = new Uint8Array([1, 2, 3]); var arrayBuffer = uint8Array.buffer; var blob = new Blob([arrayBuffer]); … Read more
Try this: function _base64ToArrayBuffer(base64) { var binary_string = window.atob(base64); var len = binary_string.length; var bytes = new Uint8Array(len); for (var i = 0; i < len; i++) { bytes[i] = binary_string.charCodeAt(i); } return bytes.buffer; }
Instances of Buffer are also instances of Uint8Array in node.js 4.x and higher. Thus, the most efficient solution is to access the buf.buffer property directly, as per https://stackoverflow.com/a/31394257/1375574. The Buffer constructor also takes an ArrayBufferView argument if you need to go the other direction. Note that this will not create a copy, which means that … Read more
function _arrayBufferToBase64( buffer ) { var binary = ”; var bytes = new Uint8Array( buffer ); var len = bytes.byteLength; for (var i = 0; i < len; i++) { binary += String.fromCharCode( bytes[ i ] ); } return window.btoa( binary ); } but, non-native implementations are faster e.g. https://gist.github.com/958841 see http://jsperf.com/encoding-xhr-image-data/6 Updated benchmarks: https://jsben.ch/wnaZC
