How to install npm packages in BigQuery? - node.js

Question

I unfortunately can not any reliable documentation on how to use an npm package in BigQuery. I want to use the package isitblocked in BigQuery and parse the URLs in my tables through the library.
I only found this blog, but I can't re-procedure the steps there and get the following error while using webpack:
`assets by status 390 bytes [cached] 1 asset
./index.ts 2.43 KiB [built] [code generated] [1 error]
WARNING in configuration
The 'mode' option has not been set, webpack will fallback to > 'production' for this value.
Set 'mode' option to 'development' or 'production' to enable > defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/configuration/mode/
ERROR in ./index.ts 1:16
Module parse failed: Unexpected token (1:16)

import envPaths = require("env-paths");
| import Listr = require("listr");
| import fs = require("fs-extra");

The package I try to install is isitblocked.

Answer 1

I did it step by step in the google Shell and it prompted to install the webpack. Please include the mode none or production
npx webpack --config webpack.config.js --mode none
Then upload the file under dist and edit the BigQuery query to:
CREATE TEMP FUNCTION get_rand_card_number()
RETURNS STRING
LANGUAGE js
OPTIONS (
library=["gs://***your*bucket*name***/creditcard-generator.js"]
)
AS r"""
return webpackNumbers.GenCC("Amex"); # Still wrong function name
""";
CREATE TEMP FUNCTION get_rand_id()
RETURNS STRING
LANGUAGE js
AS r"""
return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {
var r = Math.random() * 4 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8);
return v.toString(4);
});
""";
SELECT
x,
get_rand_id() as unique_id,
get_rand_card_number() as credit_card_number
FROM
unnest(generate_array(1,100,1)) x
