In this video we'll walk through an Airtable Script that automatically resizes and compresses images using the Kraken.io API. For this tutorial we brought in a special guest and old friend, Matt, a New Zealand based developer extraordinaire.
//Trigger: User clicks button
// settings you change:
// ========================
let apiKey = "yourApiKeyHere";
let apiSecret = "yourSecretHere";
let originalFieldName = "Original";
let largeFieldName = "Large Web";
let largeWidth = 630;
let smallFieldName = "Small Web";
let smallWidth = 416;
// ========================
// Image resize code
// ========================
let table = base.getTable("Employees");
let record = await input.recordAsync("Select an Employee whose images you would like to create", table);
// need an image there
if(record.getCellValue(originalFieldName) === null){
//console.log("Please upload an image for this record");
output.text("Please upload an image for this record");
return;
}
let imageToResizeUrl = record.getCellValue(originalFieldName)[0].url;
// send stuff to image processor
let callToKraken = await remoteFetchAsync('https://api.kraken.io/v1/url',
{
method: 'POST',

}
),
headers:{

}
)
let returnedImages = await callToKraken.json();
// some debugging checks. Uncomment to view
//console.log(returnedImages);
//console.log(returnedImages.results.small.kraked_url);
//add images as attachments into Airtable row:
// "small" and "large" under "results" below are the IDs we specified in the Kraken body above
await table.updateRecordAsync(record, {
[smallFieldName]: [ { url: returnedImages.results.small.kraked_url } ],
[largeFieldName]: [ { url: returnedImages.results.large.kraked_url } ]
})
