@env-lane/vault

The standard encrypt, restore, prune, and sanitize operations call the Rust Node-API binding from JavaScript. The native CLI resolves this package's envLanePlugin manifest and starts the platform Vault plugin executable when needed. Restore callbacks supply explicit decisions to native apply; encrypt callbacks use native candidates and frozen dotenv snapshots before native apply. The durable store format remains compatible with 0.4.2. See native migration.

Development-only reversible encrypted dotenv record storage for env-lane.

pnpm add -D @env-lane/vault

This package is intentionally unsafe for production secret management. Encryption does not make a Vault store or key file safe to publish and cannot prevent Git, backups, cloud-sync clients, logs, or other tools from copying local files. Prefer a platform Secret Manager, KMS, SOPS, age, or HashiCorp Vault for production secrets.

Library

import {
  applyRestorePlan,
  buildRestorePlan,
  encryptEnvFiles,
  loadVaultConfig,
  pruneVaultHistory,
  sanitizeVaultHistory
} from '@env-lane/vault';

await encryptEnvFiles(undefined, 'key.aes', {
  vaultConfigFile: 'env-lane.vault.ts',
  dryRun: true
});

const plan = await buildRestorePlan(undefined, 'key.aes', {
  vaultConfigFile: 'env-lane.vault.ts'
});

await applyRestorePlan(undefined, 'key.aes', plan, {
  autoApprove: true,
  decisions: plan.files.flatMap(file =>
    file.entries
      .filter(entry => entry.action !== 'identical')
      .map(entry => ({
        entryId: entry.entryId,
        decision: entry.action === 'delete' ? 'skip' : 'apply-vault'
      }))
  )
});

await pruneVaultHistory(undefined, 'key.aes', {
  keepRecent: 3,
  dryRun: true
});
await sanitizeVaultHistory(undefined, 'key.aes', {
  excluded: true,
  dryRun: true
});
await loadVaultConfig(undefined, {
  vaultConfigFile: 'env-lane.vault.ts'
});

Plans use full redaction by default and are bound to current store and dotenv state. Configure restore.redaction as full, partial, or none; partial preserves safe URL structure while hiding credentials, JWT/PASETO values, and opaque high-entropy URL components. none places plaintext values in output and approval files. Optional restore.reveal start/end counts produce hints such as <redacted:0x12......3456>; it defaults to false and never reveals a value too short to retain a hidden middle. Values and URL components shorter than eight characters are always preserved. restore.promptLoop controls wrapping in the interactive selection list and defaults to false. Selection rows show current and Vault previews inline, use a shared key-column width and responsive ten-line page, and accept Esc or q to cancel. The CLI supports one-off --redaction, --reveal <start:end>/--no-reveal, and --prompt-loop/--no-prompt-loop overrides. Deletes are selected by default; use --no-approve-deletes or approveDeletes: false to opt out. Encrypt treats missing managed files as empty by default and writes delete tombstones without creating or removing the local file; use --missing-files skip or missingFiles: 'skip' for the former skip behavior. Core and Vault library APIs never access terminal streams; diagnostics require an explicit Core context, and conflict decisions come from options or callbacks. dryRun: true reports the records and changes a push would produce without taking a write lock or creating/updating the store, sync state, or output directories.

CLI

Install a matching env-lane release alongside this package:

pnpm add -D env-lane@^0.5.0 @env-lane/vault@^0.5.0

Then use the Vault commands:

env-lane vault encrypt key.aes
env-lane vault encrypt key.aes --dry-run --json
env-lane vault plan key.aes --output restore-plan.json --json
env-lane vault apply key.aes --plan restore-plan.json --yes --non-interactive
env-lane vault prune key.aes --keep-recent 3 --dry-run

The main config must contain vault: { enabled: true }. The native CLI launches the Vault plugin using package metadata. Embedded Commander integrations may still import the separate adapter:

import { registerVaultCommands } from '@env-lane/vault/cli';

The deprecated Vault-root registerVaultCommands and cryptographic helper re-exports were removed in 0.5.0. Import the former from @env-lane/vault/cli.

Safety model

• Schema v1 records store dotenv effective values and portable config-relative file paths; versionless/v0 records remain readable.
• Schema v1 stores move directly between POSIX and Windows checkouts. autoRemapPaths is only for legacy absolute versionless/v0 records.
• exclude is a fail-closed local-only boundary; sanitize old matching history before continuing.
• Optional syncDir uses keyed fingerprints for three-way conflict detection.
• Restore plans bind digest, complete entry set, and explicit decisions before apply.
• Operations on the same store are serialized and individual files use atomic replacement.
• Multi-file writes are not a crash-atomic database transaction; rerun plan after interruption.
