Google Cloud Setup Integration Block for React

No. The drop zone checks the name ends in .json and the size is under 100 KB (a real key file is a few kilobytes), then shows its name and size in a row you can remove. The file's contents are never read in the browser and nothing is sent anywhere, and the block says "Nothing is uploaded or read in this demo" beside the drop zone. Where finish runs, a code comment marks the place to hand the file to your own server. Dropping a second file replaces the first, and a file that is not a .json or is over 100 KB is refused with a reason in the same space.

Yes. They use gcloud iam service-accounts create, gcloud projects add-iam-policy-binding three times and gcloud iam service-accounts keys create, with the service account's address built as ferrybase-loader@<project>.iam.gserviceaccount.com. They carry the project ID you typed once it is valid, and PROJECT_ID until then. The block only shows and copies them; it runs nothing.

roles/bigquery.dataEditor lets the account create tables and write rows in datasets, roles/bigquery.jobUser lets it run jobs (the load jobs that move each batch) in the project, and roles/pubsub.subscriber lets it read your events from a subscription. Change the --role lines in commandsOf to match what your product needs, and keep the roles in the paragraph above the commands in step with them. If your organization blocks key creation (the iam.disableServiceAccountKeyCreation policy), the last command is refused, which step 3 says.

US and EU are BigQuery's multi-regions: data centres in the United States, and in member states of the European Union. The line under the choice repeats which one is picked. Add regions to PLACES if you offer them.

It changes local state only and the polite status line says "Connected in this demo. Nothing was sent to Google Cloud, and no key file was read." Disconnect turns it back. Wire finish to your own endpoint, with the key file's contents read where your server can keep them safe.

Below lg the divider gives way to a rule and the end column stacks under the steps. The commands scroll sideways inside a focusable region. In a right-to-left layout the columns and the step rail flip while project IDs, commands and file names keep their left-to-right order. The header fades up once on load, and not at all with reduced motion.
