helm-ts

A Node/TypeScript client for Helm. It is modeled after the Helm CLI so if you're already comfortable with the CLI then using this client should be no problem for you.

Examples

Download and install a Helm Chart

With Helm CLI

$ helm repo add bitnami https://charts.bitnami.com/bitnami
$ helm install my-mongodb-release bitnami/mongodb

With helm-ts

await helm.repo.add('bitnami', 'https://charts.bitnami.com/bitnami');
await helm.install('my-mongodb-release', 'bitnami/mongodb');

List Helm releases

With Helm CLI:

$ helm list
 
NAME                    NAMESPACE       REVISION        UPDATED                                 STATUS          CHART           APP VERSION
my-mongodb-release      default         1               2020-11-11 22:39:35.585098 -0500 EST    deployed        mongodb-10.0.0  4.4.1           

With helm-ts

const releases: Release[] = await helm.list();
/**
 *  releases =  [
 *    {
 *      name: 'my-mongodb-release',
 *      namespace: 'default',
 *      revision: '1',
 *      updated: '2020-11-11 22:39:35.585098 -0500 EST',
 *      status: 'deployed',
 *      chart: 'mongodb-10.0.0',
 *      app_version: '4.4.1'
 *    }
 *  ]
 */

Note: Only commands that support json output will return typed objects. Otherwise a string output is returned where present.

Getting started

1. Install the npm package

$ npm install helm-ts

1. Import the package into your module

import helm from 'helm-ts';
(async () => {
  const releases = await helm.list({ namespace: 'openfaas' }); // list releases in openfaas namespace
  console.log(releases);
  /**
   * [
   *   {
   *     name: 'openfaas',
   *     namespace: 'openfaas',
   *     revision: '1',
   *     updated: '2020-10-25 22:02:45.325836 -0400 EDT',
   *     status: 'deployed',
   *     chart: 'openfaas-6.0.4',
   *     'app_version': ''
   *   }
   * ]
   */
})();

Roadmap

This project is currently a WIP. I will be mostly focused on implementing the most commonly used helm commands first.
