# Hex Local Dev Loop ## Overview Set up a development workflow for Hex API orchestration with mocked API responses and testing. ## Instructions ### Step 1: Project Structure ``` hex-orchestrator/ ├── src/hex/ │ ├── client.ts # API client │ ├── orchestrator.ts # Pipeline runner │ └── types.ts # TypeScript interfaces ├── tests/ │ ├── fixtures/ # Mock API responses │ └── orchestrator.test.ts ├── .env.local └── package.json ``` ### Step 2: Typed Hex Client ```typescript // src/hex/client.ts export class HexClient { constructor(private token: string, private baseUrl = 'https://app.hex.tech/api/v1') {} async listProjects() { return this.get('/projects'); } async runProject(projectId: string, inputParams?: Record<string, any>) { return this.post(`/project/${projectId}/run`, { inputParams: inputParams || {}, updateCacheResult: true }); } async getRunStatus(projectId: string, runId: string) { return this.get(`/project/${projectId}/run/${runId}`); } async cancelRun(projectId: string, runId: string) { return this.delete(`/project/${projectId}/run/${runId}`); } private async get(path: string) { const res = await fetch(`${this.baseUrl}${path}`, { headers: { 'Authorization': `Bearer ${this.token}` } }); if (!res.ok) throw new Error(`Hex API ${res.status}`); return res.json(); } private async post(path: string, body: any) { const res = await fetch(`${this.baseUrl}${path}`, { method: 'POST', hea...
