17.2.4 (2026-02-05)

Changed

  • Make DotenvPopulateInput accept NodeJS.ProcessEnv type (#915)
  • Give back to dotenv by checking out my newest project vestauth. It is auth for agents. Thank you for using my software.

17.2.3 (2025-09-29)

Changed

  • Fixed typescript error definition (#912)

17.2.2 (2025-09-02)

Added

  • 🙏 A big thank you to new sponsor Tuple.app - the premier screen sharing app for developers on macOS and Windows. Go check them out. It's wonderful and generous of them to give back to open source by sponsoring dotenv. Give them some love back.

17.2.1 (2025-07-24)

Changed

  • Fix clickable tip links by removing parentheses (#897)

17.2.0 (2025-07-09)

Added

  • Optionally specify DOTENV_CONFIG_QUIET=true in your environment or .env file to quiet the runtime log (#889)

  • Just like dotenv any DOTENV_CONFIG_ environment variables take precedence over any code set options like ({quiet: false})

    # .env
DOTENV_CONFIG_QUIET=true
HELLO="World"

    // index.js
require('dotenv').config()
console.log(`Hello ${process.env.HELLO}`)

    $ node index.js
Hello World

or

$ DOTENV_CONFIG_QUIET=true node index.js

17.1.0 (2025-07-07)

Added

  • Add additional security and configuration tips to the runtime log (#884)

  • Dim the tips text from the main injection information text

    const TIPS = [
'🔐 encrypt with dotenvx: https://dotenvx.com',
'🔐 prevent committing .env to code: https://dotenvx.com/precommit',
'🔐 prevent building .env in docker: https://dotenvx.com/prebuild',
'🛠️  run anywhere with `dotenvx run -- yourcommand`',
'⚙️  specify custom .env file path with { path: \'/custom/path/.env\' }',
'⚙️  enable debug logging with { debug: true }',
'⚙️  override existing env vars with { override: true }',
'⚙️  suppress all logs with { quiet: true }',
'⚙️  write to custom object with { processEnv: myObject }',
'⚙️  load multiple .env files with { path: [\'.env.local\', \'.env\'] }'
]

17.0.1 (2025-07-01)

Changed

  • Patched injected log to count only populated/set keys to process.env (#879)

17.0.0 (2025-06-27)

Changed

  • Default quiet to false - informational (file and keys count) runtime log message shows by default (#875)

16.6.1 (2025-06-27)

Changed

  • Default quiet to true – hiding the runtime log message (#874)
  • NOTICE: 17.0.0 will be released with quiet defaulting to false. Use config({ quiet: true }) to suppress.
  • And check out the new dotenvx. As coding workflows evolve and agents increasingly handle secrets, encrypted .env files offer a much safer way to deploy both agents and code together with secure secrets. Simply switch require('dotenv').config() for require('@dotenvx/dotenvx').config().

16.6.0 (2025-06-26)

Added

  • Default log helpful message [dotenv@16.6.0] injecting env (1) from .env (#870)
  • Use { quiet: true } to suppress
  • Aligns dotenv more closely with dotenvx.

16.5.0 (2025-04-07)

Added

  • 🎉 Added new sponsor Graphite - the AI developer productivity platform helping teams on GitHub ship higher quality software, faster.

[!TIP] Become a sponsor

Changed

  • Minor README clarifications
  • Development ONLY: updated devDependencies as recommended for development only security risks (#658)

16.0.0 (2022-02-02)

Added

  • Breaking: Backtick support 🎉 (#615)

If you had values containing the backtick character, please quote those values with either single or double quotes.

15.0.1 (2022-02-02)

Changed

  • Properly parse empty single or double quoted values 🐞 (#614)

15.0.0 (2022-01-31)

v15.0.0 is a major new release with some important breaking changes.

Added

Changed

  • Breaking: # marks the beginning of a comment (UNLESS the value is wrapped in quotes. Please update your .env files to wrap in quotes any values containing #. For example: SECRET_HASH="something-with-a-#-hash").

..Understandably, (as some teams have noted) this is tedious to do across the entire team. To make it less tedious, we recommend using dotenv cli going forward. It's an optional plugin that will keep your .env files in sync between machines, environments, or team members.
