GitHub: Get a diff of the dependencies between commits

← Dependency graph operations · Get started

Operation github.dependency_graph_diff_range

Provider route: GET /repos/{owner}/{repo}/dependency-graph/compare/{basehead}. Alter supplies the connection’s credentials and routing.

Call through Alter

Install @alter-ai/sdk @alter-ai/github with npm, or alter-sdk-github with pip. Supply your connected customer’s grant ID and the arguments described below.

import { App } from "@alter-ai/sdk";
import { GitHubIntegration } from "@alter-ai/github";

async function execute(input: Parameters<GitHubIntegration["dependencyGraph"]["dependencyGraphDiffRange"]>[0]) {
  const app = new App({ apiKey: process.env.ALTER_API_KEY! });
  try {
    const provider = new GitHubIntegration(app, { grantId: process.env.PROVIDER_GRANT_ID! });
    const call = await provider.dependencyGraph.dependencyGraphDiffRange(input);
    const result = await call.wait();
    return result.bodyJson();
  } finally {
    await app.close();
  }
}

import os
from alter_sdk import App
from alter_sdk_github import GitHubIntegration

async def execute(arguments):
    async with App(api_key=os.environ["ALTER_API_KEY"]) as app:
        provider = GitHubIntegration(app, {"grant_id": os.environ["PROVIDER_GRANT_ID"]})
        call = await provider.dependency_graph.dependency_graph_diff_range(arguments)
        result = await call.wait()
        return result.body_json()

Policy, approvals and errors

SDK function policy ID: github.dependency_graph_diff_range. Catalog operation: dependency-graph/diff-range. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.
