Hi, is it possible to import parquet-wasm using esbuild rather than a CDN? I see that parquet-wasm is a dependency in the package.json
|
"dependencies": { |
|
"@anywidget/react": "^0.0.4", |
|
"@babel/runtime": "^7.24.1", |
|
"@deck.gl/core": "^8.9.35", |
|
"@deck.gl/extensions": "^8.9.35", |
|
"@deck.gl/layers": "^8.9.35", |
|
"@deck.gl/react": "^8.9.35", |
|
"@geoarrow/deck.gl-layers": "^0.3.0-beta.16", |
|
"apache-arrow": "^15.0.2", |
|
"maplibre-gl": "^3.6.2", |
|
"parquet-wasm": "0.5.0", |
|
"react": "^18.2.0", |
|
"react-dom": "^18.2.0", |
|
"react-map-gl": "^7.1.7", |
|
"uuid": "^9.0.1" |
|
}, |
but lonboard is also referencing a CDN here:
|
import _initParquetWasm, { readParquet } from "parquet-wasm/esm/arrow2"; |
|
import * as arrow from "apache-arrow"; |
|
|
|
// NOTE: this version must be synced exactly with the parquet-wasm version in |
|
// use. |
|
const PARQUET_WASM_VERSION = "0.5.0"; |
|
const PARQUET_WASM_CDN_URL = `https://cdn.jsdelivr.net/npm/parquet-wasm@${PARQUET_WASM_VERSION}/esm/arrow2_bg.wasm`; |
|
let WASM_READY: boolean = false; |
|
|
|
export async function initParquetWasm() { |
|
if (WASM_READY) { |
|
return; |
|
} |
|
|
|
await _initParquetWasm(PARQUET_WASM_CDN_URL); |
|
WASM_READY = true; |
|
} |
|
|
I ask because I'm trying to test out lonboard on a service that prevents me from making front-end requests to CDNs (I would have to request the URL be added to an allowlist, but I want to see if I can avoid this by bundling the code with esbuild but I was running into errors when I tried to use the bundled version - kylebarron/parquet-wasm#488).
