Maintainx Local Dev Loop

MaintainX Local Dev Loop

Overview

Set up an efficient local development workflow for building and testing MaintainX integrations with hot reload, mock servers, and automated testing.

Prerequisites

• Completed maintainx-install-auth setup
• Node.js 18+ installed
• MAINTAINX_API_KEY environment variable set

Instructions

Step 1: Initialize TypeScript Project

mkdir maintainx-integration && cd maintainx-integration
npm init -y
npm install axios dotenv
npm install -D typescript tsx vitest @types/node
npx tsc --init --target ES2022 --module NodeNext --moduleResolution nodenext --outDir dist

Create tsconfig.json paths:

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "NodeNext",
    "moduleResolution": "nodenext",
    "outDir": "dist",
    "strict": true,
    "esModuleInterop": true
  },
  "include": ["src/**/*"]
}

Step 2: Project Structure

maintainx-integration/
├── src/
│   ├── client.ts          # MaintainX API client (from install-auth)
│   ├── work-orders.ts     # Work order service layer
│   └── sync.ts            # Data sync logic
├── tests/
│   ├── client.test.ts     # Unit tests with mocks
│   └── integration.test.ts # Live API tests
├── .env                   # MAINTAINX_API_KEY=...
├── .env.example           # MAINTAINX_API_KEY=your-key-here
├── package.json
└── tsconfig.json

Step 3: Dev Scripts in package.json

{
  "scripts": {
    "dev": "tsx watch src/index.ts",
    "test": "vitest run",
    "test:watch": "vitest",
    "test:integration": "INTEGRATION=true vitest run tests/integration.test.ts",
    "build": "tsc",
    "repl": "tsx src/repl.ts"
  }
}

Step 4: Write Unit Tests with Mocked API

// tests/client.test.ts
import { describe, it, expect, vi, beforeEach } from 'vitest';
import axios from 'axios';

vi.mock('axios');

describe('MaintainXClient', () => {
  beforeEach(() => {
    vi.resetAllMocks();
    process.env.MAINTAINX_API_KEY = 'test-key-123';
  });

  it('creates a work order', async () => {
    const mockResponse = {
      data: { id: 1, title: 'Test WO', status: 'OPEN' },
    };
    vi.mocked(axios.create).mockReturnValue({
      post: vi.fn().mockResolvedValue(mockResponse),
      interceptors: { response: { use: vi.fn() } },
    } as any);

    const { MaintainXClient } = await import('../src/client');
    const client = new MaintainXClient();
    const result = await client.createWorkOrder({ title: 'Test WO' });

    expect(result.data.title).toBe('Test WO');
    expect(result.data.status).toBe('OPEN');
  });

  it('paginates work orders', async () => {
    const page1 = { data: { workOrders: [{ id: 1 }], cursor: 'abc' } };
    const page2 = { data: { workOrders: [{ id: 2 }], cursor: null } };
    const getMock = vi.fn()
      .mockResolvedValueOnce(page1)
      .mockResolvedValueOnce(page2);

    vi.mocked(axios.create).mockReturnValue({
      get: getMock,
      interceptors: { response: { use: vi.fn() } },
    } as any);

    const { MaintainXClient } = await import('../src/client');
    const client = new MaintainXClient();

    const all = [];
    let cursor: string | undefined;
    do {
      const { data } = await client.getWorkOrders({ cursor });
      all.push(...data.workOrders);
      cursor = data.cursor;
    } while (cursor);

    expect(all).toHaveLength(2);
  });
});

Step 5: Interactive REPL

// src/repl.ts
import * as repl from 'node:repl';
import 'dotenv/config';
import { MaintainXClient } from './client';

const client = new MaintainXClient();
console.log('MaintainX REPL ready. `client` is available.');
console.log('Try: await client.getWorkOrders({ limit: 3 })');

const r = repl.start({ prompt: 'maintainx> ' });
r.context.client = client;

# Start REPL
npm run repl
# maintainx> const { data } = await client.getWorkOrders({ limit: 3 })
# maintainx> data.workOrders.map(wo => wo.title)

Output

• TypeScript project configured with tsx watch for hot reload
• Vitest unit tests with mocked MaintainX API responses
• Interactive REPL for exploring the API
• .env.example template for team onboarding
• Dev/test/build scripts in package.json

Examples

Docker-based dev environment:

# Dockerfile.dev
FROM node:20-slim
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["npm", "run", "dev"]

# docker-compose.dev.yml
services:
  app:
    build: { dockerfile: Dockerfile.dev }
    env_file: .env
    volumes: ["./src:/app/src"]

Run integration tests against live API:

INTEGRATION=true npm run test:integration
