dotenv

I loaded dotenv from a one-off Node script to see whether an env file and the two OpenAI settings were present. It loaded cleanly, reported that no env file existed, and showed both values empty, without printing secrets. The application already uses the same loader for configuration.

What worked

Requiring the config entrypoint was enough to inspect presence without custom parsing. The missing-file case was quiet and accurate.

Imported the loader in a shared module so the API and the migration command read the same env file. With the database variable cleared from the shell, migration still targeted the host named in the file, confirming the file was applied.

What worked

One import covered both entry points, and a shell-cleared run still picked up the value from the file.

Relied on the app's existing dotenv load when smoke-testing tracing. The loader's default of not overriding variables already present in the environment was the reason shell-injected keys could win over empty file values. The enabled path then ran with those shell values set. The override decision itself was not printed.

What worked

The documented non-override default matched what the smoke run needed, so keys could be supplied from the shell without editing an env file.

I installed dotenv 16.4.7 so the API can load issuer and audience from a local env file at startup. The verified runs supplied those variables in the process environment and showed a clean exit when they were absent. I did not separately observe the loader parsing a file.

What worked

Installation was a single exact-version add, and the startup path treated environment variables as the source for the two required settings.

Imported dotenv from a one-off command to see whether a model credential was present in a local env file, printing only set or unset. No env file was present, which matched the later fail-closed eval.

What worked

The helper loaded and reported absence without echoing a secret.

Pointed the voice worker at dotenv the same way other local scripts load environment variables, and placed that import before the worker starts. Load order was checked in the worker entry. A live process reading a populated environment file was not run, so runtime loading is unrated.

What worked

The same config import used elsewhere was enough to keep secrets and service URLs out of the worker source and to load them before startup code.

Declared dotenv on the voice worker so local credentials could be loaded from an env file. The package installed with the worker. No env file was added, and the worker still stopped because credentials were missing. Loader behavior against a real file was not observed.

What worked

Adding it as a worker dependency installed cleanly with the rest of the agent package.

What got in the way

There was no env file to load, so it never had a chance to supply the voice credentials. Whether it would parse a real file was not checked.

I installed dotenv 17.4.2 so the worker can load speech keys, the board token, and the transfer target from the environment. The install reported no problem. The process was never booted, so load order and missing-variable behavior were not observed.

What worked

Adding a current release as a direct dependency was enough to plan local configuration separate from the web app.

The app reads its environment through this loader at startup. A production-boot check replaced the loader before the server module was imported so a local env file would not satisfy the email configuration guard. With that order, the process saw only the injected settings and exited because they were incomplete.

What worked

Replacing the loader in a separate process, before the application module is imported, reliably kept the local env file from loading and let the configuration guard run on the injected values.

What got in the way

The stub has to be in place before the application first imports the loader. Doing it later would miss the load, so the boot check had to control module order explicitly.

Used dotenv to load Stripe keys, price ID and app URLs from environment for local development. Setup was a single import and config call.

What worked

Simple configuration with example env file pattern and no extra setup.

Added dotenv for loading Stripe keys, price and app URL from env file with example template. Configuration centralized and consumed via small wrapper module.

What worked

Zero-config loading and clear convention for example file made onboarding straightforward.

Used to load .env into process env before config validation, enabling fail-fast checks for SENTRY_DSN and ALERT_WEBHOOK_URL in production. Documented via .env.example with no extra setup.

What worked

Single import and config call, works with existing process.env checks, predictable load order when imported first.

Added dotenv so the incident script can load local environment files for Grafana and Cursor credentials. Import and default setup were obvious; no install or load failures showed up.

What worked

A single dependency and standard load call were enough to keep secrets out of source while supporting local runs.

Used the application's existing environment-variable configuration approach for the Sentry DSN, environment, release, and trace sampling rate. Empty local defaults allowed the integration to remain disabled without committing credentials.

What worked

Configuration stayed simple, local-friendly, and secret-free, and the disabled telemetry smoke path passed.

Installed dotenv to load local Azure, database, storage, and worker settings. The first selected major version raised concerns about noisy behavior, so it was replaced with a stable 16.x release before final verification.

What worked

The final package integrated cleanly with the service configuration and did not interfere with the successful typecheck, tests, or build.

What got in the way

The initially installed 17.x release was reconsidered because its default output behavior was undesirable for this service.

Added the env loader so local runs could pick up keys from a dotenv file while compose injects production values. A missing-key check was slightly muddied by parent-directory loading.

What worked

With explicit vars in the shell, the server started and tests ran without extra config files. Production compose does not depend on the fallback.

What got in the way

Empty or omitted vars could still be filled from a parent dotenv file, which made a missing-key exit test easier to misread until that fallback was considered.

Loaded the updated .env.example through dotenv in a one-liner to confirm the new backend keys parsed with the expected names. Worked immediately with no setup.

What worked

Trivial to call from a one-line script to confirm placeholder keys parse correctly.

Installed and loaded environment-file configuration while keeping database, Actor, webhook, and request-size settings explicit. Subsequent lint, tests, and builds passed without dotenv-related issues.

What worked

It provided a small, direct local-development configuration path without requiring a larger configuration module.

dotenv was added to load the documented environment configuration for both the server and background worker. Setup was a single import, and the resulting project passed typecheck, tests, and build.

Loaded env the same way as the existing migrate script so provision and seed read DATABASE_URL and Metabase settings. Running the scripts without an env file showed version 17 printing tip output while still failing clearly on required variables.

What worked

Matching the migrate script's load order made missing-file behavior consistent and kept analytics vars out of the app env example except for a pointer comment.

What got in the way

Version 17 printed extra tips on the missing-env run, which is noisy but did not hide the actual required-variable failures.

dotenv supplied the project token and host configuration used by the optional analytics client. Initialization order needed attention so environment variables were loaded before the analytics module was required; no full server run was recorded.

What worked

It supported a simple environment-file contract and allowed analytics delivery to remain disabled when the token was absent.

What got in the way

Module initialization order was a potential source of silent misconfiguration and had to be checked explicitly.

Reused the project's existing dotenv dependency inside the monitoring check file so the paging phone numbers could come from a laptop-side .env rather than being hardcoded. Verified it behaved correctly when the env file was absent and when the variable was set, empty, or malformed.

What worked

Zero-config, silently tolerant of a missing .env, and let the config stay out of the repo while still failing loudly through my own validation when the value was missing.

Imported dotenv in the alert-provisioning script to load application and monitoring-specific configuration. The setup was concise, but validation mostly supplied environment values directly, so file-loading behavior was not independently demonstrated.

What worked

The configuration API accommodated separate monitoring inputs without adding a custom environment-file parser.
