Utilities

findRepoRoot()

Find the repository root by traversing up from current directory.

import { findRepoRoot } from "@codecompose/envi";

const repoRoot = await findRepoRoot();
// Returns: "/path/to/repo" or null if user cancelled

findEnvFiles()

Find all .env files in a directory.

import { findEnvFiles } from "@codecompose/envi";

const files = await findEnvFiles("/path/to/repo");
// Returns: [".env", "apps/web/.env.local", ...]

parseEnvFile()

Parse a .env file with comment preservation.

import { parseEnvFile } from "@codecompose/envi";

const env = parseEnvFile("/path/to/.env");
// Returns: {
//   __l_00: "# Comment",
//   __i_00: "# Inline comment",
//   KEY: "value"
// }

Storage

getStorageDir()

Get the storage directory path.

import { getStorageDir } from "@codecompose/envi";

const dir = getStorageDir();
// Returns: "/Users/you/.envi/store"

getEnviDir()

Get the envi root directory path.

import { getEnviDir } from "@codecompose/envi";

const dir = getEnviDir();
// Returns: "/Users/you/.envi"

getPackageName()

Read package name from repository.

import { getPackageName } from "@codecompose/envi";

const name = getPackageName("/path/to/repo");
// Returns: "@org/package" or null

saveToStorage()

Save environment configuration to storage.

import { saveToStorage } from "@codecompose/envi";

const hasChanges = saveToStorage(
  "/path/to/repo",
  [
    {
      path: ".env",
      env: { KEY: "value" },
    },
  ],
  "@org/package", // Optional package name
  { encryptionKey: null }, // Optional encryption settings
);
// Returns: true if file was updated, false if no changes

The optional fourth argument is SaveToStorageOptions. When encryptionKey is set, each file's env block is encrypted with encrypt(JSON.stringify(env), encryptionKey) before being written, and the no-op comparison reads/decrypts the existing store with the same key.

Per-repo Config (envi.config.maml)

Helpers for the per-repo envi.config.maml file. The legacy filename envi.maml is still read so already-committed files keep working — reads prefer the canonical name and fall back to legacy; writes target whichever file is on disk (and create the canonical name when neither exists).

KEY_FILE_NAME

import { KEY_FILE_NAME } from "@codecompose/envi";

console.log(KEY_FILE_NAME); // "envi.config.maml"

LEGACY_KEY_FILE_NAME

import { LEGACY_KEY_FILE_NAME } from "@codecompose/envi";

console.log(LEGACY_KEY_FILE_NAME); // "envi.maml"

generateKey()

Generate a new 32-byte random key as a base64url string.

import { generateKey } from "@codecompose/envi";

const key = generateKey();
// Returns: ~43-character base64url string

readEncryptionKey()

Read the encryption_key from envi.config.maml (preferred) or the legacy envi.maml (fallback). Emits a one-time info hint when the legacy file is read.

import { readEncryptionKey } from "@codecompose/envi";

const key = readEncryptionKey("/path/to/repo");
// Returns: string or null

readCapturePatterns()

Read additional capture patterns from the per-repo config. Reads from whichever filename is on disk (canonical preferred). Returns [] when the file or capture_patterns field is missing.

import { readCapturePatterns } from "@codecompose/envi";

const patterns = readCapturePatterns("/path/to/repo");
// Returns: string[]

writeEncryptionKey()

Write or update the per-repo config with a key. If only the legacy envi.maml is on disk, it is edited in place — migration to the canonical name is left to the user so they can commit the rename. Creates a new envi.config.maml with a header comment when neither file exists. Refuses to overwrite an existing encryption_key unless { force: true } is passed. Returns the basename of the file that was written (envi.config.maml or envi.maml).

import { writeEncryptionKey } from "@codecompose/envi";

const filename = writeEncryptionKey("/path/to/repo", key, { force: false });
// Throws Error when force is false and a key is already set.

hasKeyFile()

Check whether either envi.config.maml or the legacy envi.maml exists in a repository (does not check whether encryption_key is set inside).

import { hasKeyFile } from "@codecompose/envi";

const exists = hasKeyFile("/path/to/repo");
// Returns: boolean

findKeyFile()

Return the basename of the per-repo config file present on disk — envi.config.maml if the canonical file exists, envi.maml if only the legacy file does, or null when neither exists. Use this to surface the actual filename in user-facing messages instead of always naming the canonical constant.

import { findKeyFile } from "@codecompose/envi";

const filename = findKeyFile("/path/to/repo");
// Returns: "envi.config.maml" | "envi.maml" | null

Configuration

readConfig()

Read global configuration.

import { readConfig } from "@codecompose/envi";

const config = readConfig();
// Returns: {
//   use_version_control: "github" | false,
//   manifest_files: string[]
// }

writeConfig()

Write global configuration.

import { writeConfig } from "@codecompose/envi";

writeConfig({
  use_version_control: "github",
  manifest_files: ["my-custom.json"],
});

updateConfig()

Update global configuration (merges with existing).

import { updateConfig } from "@codecompose/envi";

// Update version control setting
updateConfig({ use_version_control: false });

// Add additional manifest files to check (on top of defaults)
updateConfig({
  manifest_files: [
    "my-custom.json", // Custom manifest file
    "app.yaml", // Another custom manifest
  ],
});

const rustExtractor = PACKAGE_EXTRACTORS.find(
  (e) => e.filename === "Cargo.toml",
);

if (rustExtractor) {
  const packageName = rustExtractor.extract("/path/to/rust/project");

  if (name) {
    console.log(`Found ${name} from ${extractor.filename}`);
    break;
  }
}

import type { PackageExtractor } from "@codecompose/envi";

const customExtractor: PackageExtractor = {
  filename: "my-manifest.json",
  extract: (repoPath: string): string | null => {
    // Custom extraction logic
    return "custom-package-name";
  },
};

Types

EnviStore

Structure of stored MAML files.

import type { EnviStore, EnviStoreFile } from "@codecompose/envi";

const store: EnviStore = {
  __envi_version: 1,
  metadata: {
    updated_from: "/path/to/repo",
    updated_at: "2025-11-01T12:00:00.000Z",
  },
  files: [
    {
      path: ".env",
      env: { KEY: "value" },
    },
  ],
};

EnviStore.files is an array of EnviStoreFile, a discriminated union:

type EnviStoreFile =
  | { path: string; env: EnvObject } // plaintext
  | { path: string; encrypted_env: string }; // ciphertext (base64)

The encrypted_env variant is produced when saveToStorage is called with { encryptionKey }. The base64 string is encrypt(JSON.stringify(env), key) from ~/utils/encryption.

EnvObject

Parsed environment file object.

import type { EnvObject } from "@codecompose/envi";

const env: EnvObject = {
  __l_00: "# Comment",
  __i_00: "# Inline comment",
  KEY: "value",
};

EnviConfig

Global configuration structure.

import type { EnviConfig } from "@codecompose/envi";

const config: EnviConfig = {
  use_version_control: "github" | false,
  manifest_files: string[],
};

// Example with custom values (adds to defaults)
const customConfig: EnviConfig = {
  use_version_control: false,
  manifest_files: [
    "my-custom.json",  // Checked before defaults
    "app.yaml",
  ],
};

PackageExtractor

Package extractor interface.

import type { PackageExtractor } from "@codecompose/envi";

interface PackageExtractor {
  /** The filename to look for in repository root */
  filename: string;
  /** Extract package name from file, returns null if extraction fails */
  extract: (repositoryPath: string) => string | null;
}

Example: Custom Backup Script

import {
  findRepoRoot,
  findEnvFiles,
  parseEnvFile,
  saveToStorage,
} from "@codecompose/envi";
import { join } from "node:path";

async function backupEnvFiles(repoPath: string) {
  // Find repository root
  const root = await findRepoRoot(repoPath);
  if (!root) {
    throw new Error("Not a repository");
  }

  // Find all env files
  const filePaths = await findEnvFiles(root);

  // Parse each file
  const envFiles = filePaths.map((relativePath) => {
    const absolutePath = join(root, relativePath);
    const env = parseEnvFile(absolutePath);
    return { path: relativePath, env };
  });

  // Save to storage
  const hasChanges = saveToStorage(root, envFiles);

  return { hasChanges, fileCount: envFiles.length };
}

// Usage
const result = await backupEnvFiles(process.cwd());
console.log(`Backed up ${result.fileCount} files`);
