Dominik Moritz commented on ARROW-2686:
---------------------------------------
import { Table } from "@apache-arrow/es2015-esm";
fetch(require("../data/flights-10k.arrow")).then(response => {
response.arrayBuffer().then(buffer => {
const table = Table.from(new Uint8Array(buffer));
console.log(table.toString());
});
});
Works. Feel free to close this or improve the documentation.
> Cannot load .arrow file in JavaScript
> -------------------------------------
>
> Key: ARROW-2686
> URL: https://issues.apache.org/jira/browse/ARROW-2686
> Project: Apache Arrow
> Issue Type: Improvement
> Components: JavaScript
> Reporter: Dominik Moritz
> Priority: Major
>
> I'm trying to create load an arrow file in IPC format.
> First, I load the library
> import { Table } from "@apache-arrow/es2015-esm";
> Then, I fetch the file and convert it to the buffer (it would be nice if this
> wasn't necessary)
> fetch(require("../data/flights-10k.arrow")).then(response => {
> response.blob().then(blob => {
> let arrayBuffer;
> const fileReader = new FileReader();
> fileReader.onload = function() {
> arrayBuffer = this.result;
> const table = Table.from(arrayBuffer);
> console.log(table.toString());
> };
> fileReader.readAsArrayBuffer(blob);
> });
> });
> Now I get the error "Uncaught TypeError: Cannot read property 'fields' of
> undefined"
