This Babel plugin looks for imports in your code with ssm: prefix and replaces them with actual parameter values from AWS Systems Manager.

$ npm i @grabvintage/babel-plugin-transform-ssm

$ yarn add @grabvintage/babel-plugin-transform-ssm

The only configurable parameter is prefix — a part of the parameter path that's appended to every requested parameter. For example, if you request a parameter ssm:/test with prefix /app, the plugin will be looking for /app/test parameter.

AWS credentials are configured via CLI. Please make sure that AWS_PROFILE (or AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) and AWS_REGION environment variables are set.

babel.config.js

module.exports = {
  plugins: [['@grabvintage/babel-plugin-transform-ssm', { prefix: `/grabvintage/${process.env.ENV || 'default'}` }]],
};

Currently only imports are supported. Open an issue if you need support for any other syntax.

before

import databaseName from 'ssm:/database/name';

after

const databaseName = 'grabvintage-default';

TypeScript will be complaining about missing modules on every import that starts with ssm: prefix. To mitigate this, add a definition file somewhere in your project with the following content:

ssm.d.ts

declare module 'ssm:/database/name' {
  const parameter: string | undefined;
  export = parameter;
}
