Yes, there’s a simple way without manually writing a loop (the loop still exists somewhere in background): new Uint16Array([1,2,3]); That’s all. Of course, floating numbers will be rounded down and big numbers will overflow. Converting typed array to buffer The buffer of any typed array is accessible through .buffer property, as anyone can read on … Read more
Saving the file was as easy as creating a new Buffer with the Uint8Array object : // chunk is the Uint8Array object fs.appendFile(path, Buffer.from(chunk), function (err) { if (err) { fut.throw(err); } else { fut.return(chunk.length); } });
You can create a new TypedArray with a new ArrayBuffer, but you can’t change the size of an existing buffer function concatTypedArrays(a, b) { // a, b TypedArray of same type var c = new (a.constructor)(a.length + b.length); c.set(a, 0); c.set(b, a.length); return c; } Now can do var a = new Uint8Array(2), b = … Read more
Why not using a Blob ? (I realize it might not have been available at that time). Just create a Blob with your data, like var blob = new Blob([array1,array2,string,…]) and turn it back into an ArrayBuffer (if needed) using a FileReader (see this). Check this : What’s the difference between BlobBuilder and the new … 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
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 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
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
