SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Managing secrets across local development, CI pipelines, and Vercel deployments often means scattered .env files, unclear token scoping, and no audit trail. This Skill provides sourced, step-by-step guidance for adopting Doppler as a single secrets control plane for a SvelteKit on Vercel stack. ## Core Features & Use Cases - Project and config modeling: Design Doppler workplace/project/config hierarchies (dev/stg/prd, Personal Configs, branch configs) and avoid the one-project-per-team anti-pattern. - Local dev and Vercel sync: Replace .env files with doppler run injection, commit a doppler.yaml, and set up per-environment Doppler-to-Vercel syncs with Sensitive variable types. - Tokens, CI, rotation, and audit: Scope Service Tokens per config, wire GitHub Actions via the native sync, Secrets Fetch Action, or OIDC, configure two-secret-strategy rotation, and use Access Logs versus Activity Logs. - Use Case: A team migrating a SvelteKit app off .env files can follow the guides to run doppler setup, wrap npm run dev with doppler run, sync stg/prd configs to Vercel Preview and Production, and authenticate GitHub Actions with OIDC instead of a static token. ## Quick Start Ask the agent to set up Doppler for your SvelteKit project, replacing your .env file with doppler run and syncing secrets to Vercel.

Frequently Asked Questions about doppler-stinger

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I replace .env files with Doppler in a SvelteKit app?▼

Run doppler login once, then doppler setup in the repo root to bind a project and config, and wrap scripts with doppler run, for example doppler run -- npm run dev. Commit a doppler.yaml so teammates get the same setup, then delete the .env files and any code reading them.

How do I sync Doppler secrets to Vercel?▼

Create one Doppler integration sync per Vercel environment, since Development, Preview, and Production each need separate authorization. Map Doppler configs such as stg to Vercel Preview and prd to Production, and use Vercel's Sensitive variable type, which is the default for new syncs.

Should I use Doppler or just Vercel environment variables?▼

Doppler earns its place when secrets must reach more than Vercel, when credentials need rotation, when a per-secret access audit trail is required, or when access control must be finer than Vercel project settings. A single-service app with no CI secrets or compliance needs can legitimately stay on Vercel Sensitive variables.

How do I use Doppler secrets in GitHub Actions?▼

Doppler recommends the native GitHub sync integration first, then the dopplerhq/secrets-fetch-action with OIDC or a Service Token, and raw doppler run only as a last resort because it does not auto-mask values. Scope one Service Token or identity per config and never reuse tokens across stg and prd.

Can Doppler rotate Neon Postgres credentials automatically?▼

The archived research documents rotation for AWS Postgres and GCP Cloud SQL Postgres but does not confirm Neon as a supported rotation target. Verify against Doppler's live integrations catalog before promising automated Neon connection-string rotation.

Why does my Doppler-to-Vercel sync fail with a duplicate variable error?▼

The error means a variable with the same name was added manually in the Vercel dashboard rather than through the sync. Remove the manually-added variable in Vercel, since Doppler will not overwrite it, and the sync will then proceed.
