DMNO makes your configuration safer and smarter.
It integrates with the tools you already use and it's powered by TypeScript and Vite.

Get started ->

npx dmno init

Schema-defined configuration

.dmno/config.mts - sample config file

import { DmnoBaseTypes, defineDmnoService, switchBy } from 'dmno';
import { EncryptedVaultDmnoPlugin, EncryptedVaultTypes } from '@dmno/encrypted-vault-plugin';
import { OnePasswordDmnoPlugin, OnePasswordTypes } from '@dmno/1password-plugin';

// use a plugin to fetch secrets from a secure backend like 1Password
const OnePass = new OnePasswordDmnoPlugin('1pass', {
  token: configPath('OP_TOKEN'),
});
// or store them encrypted within your repo
const MyProdVault = new EncryptedVaultDmnoPlugin('vault', {
  key: configPath('DMNO_VAULT_KEY'),
});

export default defineDmnoService({
  settings: {
    // automatically detect and prevent leaks
    interceptSensitiveLeakRequests: true,
    redactSensitiveLogs: true,
    preventClientLeaks: true,
  },
  // re-use items defined in other services
  pick: ['API_KEY', 'DB_URL', 'DMNO_ENV'],
  // more config specific to this service
  schema: {
    DMNO_VAULT_KEY: {
      // re-use existing types with validation and docs info built-in
      extends: EncryptedVaultTypes.encryptionKey,
    },
    OP_TOKEN: {
      extends: OnePasswordTypes.serviceAccountToken,
    },
    SAAS_API_KEY: {
      // load different values based on any other value
      value: switchBy('DMNO_ENV', {
        _default: 'my-dev-key',
        production: MyProdVault.item(),
      }),
    },
    SAAS_PROJECT_TAG: {
      // use a function to set a value - reference any other config
      value: (ctx) => `myapp_${DMNO_CONFIG.DMNO_ENV}`,
    },
  }
});
