Module shared 

Primitives shared across the AWS Amplify (amplify) handlers: ARN synthesis, deterministic id derivation, timestamps, and default-domain / webhook-URL construction. Kept in one place so the create / get paths cannot diverge on wire format.

Functions

access_log_url

A presigned access-log download URL.

app_arn

The AWS Amplify app ARN, arn:aws:amplify:{region}:{account}:apps/{app_id}.

artifact_url

The artifact download URL for a build artifact.

backend_environment_arn

The backend-environment ARN, .../apps/{app_id}/backendenvironments/{name}.

branch_arn

The branch ARN, .../apps/{app_id}/branches/{branch}.

certificate_verification_dns_record

The ACM certificate-verification DNS record AWS surfaces while a domain is being verified.

decode_artifact_id

Reverse encode_artifact_id. Returns None for an id we did not mint.

default_domain

The default *.amplifyapp.com domain AWS assigns every app.

domain_arn

The domain-association ARN, .../apps/{app_id}/domains/{domain}.

encode_artifact_id

Encode an artifact id so GetArtifactUrl can resolve it back to its (app_id, branch, job_id, file_name) without a lookup table. AWS artifact ids are opaque; ours are a reversible base64url blob.

hash_str

FNV-1a hash for deterministic synthesis of ids / hosts from a seed so a given resource’s derived value is stable across reads and restarts.

job_arn

The job ARN, .../apps/{app_id}/branches/{branch}/jobs/{job_id}.

new_app_id

Generate a fresh Amplify app id of AWS’s ^d[a-z0-9]+$ form: a d prefix followed by 24 lowercase base-36 characters (well within the 1..=20… — AWS app ids are 14 chars, so we emit d + 13 chars = 14 total).

new_webhook_id

Generate a fresh webhook id (a UUID; Amplify’s WebhookId pattern accepts any string).

now_epoch

Current time as restJson1 epoch-seconds (a floating-point number). Amplify’s timestamp members carry no @timestampFormat, so restJson1’s default epoch-seconds applies – the AWS SDK parses the numeric value.

parse_resource_arn

Parse an Amplify ResourceArn into (app_id, Option<branch>) for the tagging operations. Only apps and branches carry tags in the model.

subdomain_dns_record

The DNS record a subdomain resolves to (a CNAME onto the app’s default domain).

thumbnail_url

A branch thumbnail URL (a presigned-style URL over the Amplify CDN).

upload_url

A presigned S3 upload URL for a manual deployment file.

webhook_arn

The webhook ARN, .../apps/{app_id}/webhooks/{webhook_id}.

webhook_url

The webhook trigger URL AWS provisions, of the form https://webhooks.amplify.{region}.amazonaws.com/prod/webhooks?id={id}&token={token}&operation=startbuild.
