How it works?

The schema is expressed as a conventional convict schema with an extra property ssmParameter that eaccepts an object with two values the path and whether it should be strict when requesting the value (error in absence of a value).

Example schema:

const schema = {
  auth: {
    default: true,
    doc: 'Whether authentication is required',
    env: 'TESTDB_AUTH',
    format: Boolean,
  },
  password: {
    default: '',
    doc: 'The example testdb password',
    env: 'TESTDB_PASS',
    format: String,
    ssmParameter: {
      path: '/testdb/db/password',
      strict: false,
    },
  },
  username: {
    default: '',
    doc: 'The example testdb username',
    env: 'TESTDB_USER',
    format: String,
    ssmParameter: {
      path: '/testdb/db/username',
      strict: true,
    },
  },
};
export default schema;

Usage

Example usage:

import * as logger from 'winston';
import SSMParamsConvictAdapter from 'ssm-params-convict-adapter';
import schema from './schema';

(async () => {
  try {
    const config = await SSMParamsConvictAdapter.convict(schema);
    logger.info(JSON.stringify(config.getProperties()));
  } catch (e) {
    logger.log('error', e);
  }
})();
