Heroku SDK

A TypeScript SDK for the Heroku Platform API, Heroku Data API, the Heroku Dashboard Backend, the Heroku Metrics API, and the Heroku Repositories API. It generates fully-typed clients at runtime from route definitions — no hand-written method per endpoint.

Installation

npm install @heroku/sdk

Usage

The simplest entry point is the HerokuSDK class. It exposes both the Platform and Data clients on a single object, plus an extension mechanism for hand-written helpers.

import { HerokuSDK } from '@heroku/sdk'
import { appExtensions } from '@heroku/sdk/extensions/platform'

// Reads token from HEROKU_API_KEY or ~/.netrc
const sdk = new HerokuSDK({ extensions: [appExtensions] })

// Upstream route (auto-generated from the API spec)
const apps = await sdk.platform.app.list()
const app  = await sdk.platform.app.info('my-app')
const favorites = await sdk.dashboardBackend.favorite.list({ type: 'app' })

// Hand-written extension method (provided by appExtensions)
await sdk.platform.app.enableMaintenance('my-app')

Extensions can also coordinate multiple services. For example, resolve a pipeline first, then resolve its GitHub repository through Repositories API with the Kolkrabbi-backed repositories service as a fallback:

import { HerokuSDK } from '@heroku/sdk'
import { reviewAppConfigExtensions } from '@heroku/sdk/extensions/platform'

const sdk = new HerokuSDK({ extensions: [reviewAppConfigExtensions] })
const pipeline = await sdk.platform.pipeline.info('my-pipeline')

if (!pipeline.id) throw new Error('Pipeline response did not include an id')
const repo = await sdk.platform.reviewAppConfig.resolveRepoName(pipeline.id)

You can also pass options directly:

const sdk = new HerokuSDK({ clientOptions: { token: 'your-api-token' } })

Common client options apply to every service. In particular, a common baseUrl overrides every service's default host, including Metrics and Repositories. Use shallow per-service overrides when only specific services should use a host or other client setting:

const sdk = new HerokuSDK({
  clientOptions: { token: 'your-api-token' },
  clientOptionsByService: {
    platform: { baseUrl: 'https://api.heroku.com' },
    repositoriesApi: { baseUrl: 'https://api.heroku.com' },
  },
})

Per-service clients

If you only need one service (and want the smallest possible bundle), import the factory directly. These return the same typed client the SDK class wraps internally.

import { createPlatformClient }     from '@heroku/sdk/platform'
import { createDataClient }         from '@heroku/sdk/data'
import { createDashboardBackendClient } from '@heroku/sdk/dashboard-backend'
import { createMetricsClient }      from '@heroku/sdk/metrics'
import { createRepositoriesClient } from '@heroku/sdk/repositories'
import { createRepositoriesApiClient } from '@heroku/sdk/repositories-api'

const platform     = createPlatformClient()
const data         = createDataClient()
const dashboardBackend = createDashboardBackendClient()
const metrics      = createMetricsClient()
const repositories = createRepositoriesClient()
const repositoriesApi = createRepositoriesApiClient()

const apps = await platform.app.list()
const favorites = await dashboardBackend.favorite.list({ type: 'app' })
