The Developer’s Toolkit: Essential Tools for commercetools Development
Published: 2024-03-11 05:04:00

When embarking on development with commercetools, a leading platform for building innovative e-commerce solutions, it’s crucial to arm yourself with the right set of tools. The developer’s toolkit for commercetools development not only includes software and libraries directly related to commercetools but also extends to third-party tools and technologies that facilitate a seamless and efficient development experience. In this LinkedIn article, we'll explore these essential tools and provide coding examples to demonstrate their practical application.

. commercetools SDKs and APIs
Tool: commercetools SDKs (Software Development Kits) for various programming languages.

Purpose: These SDKs provide a comprehensive set of tools to interact with the commercetools platform, making it easier to build, test, and deploy applications.

Coding Example: Creating a product using the commercetools JavaScript SDK.

```
const { ClientBuilder } = require('@commercetools/sdk-client');
const { createRequestBuilder } = require('@commercetools/api-request-builder');
const { createAuthMiddlewareForClientCredentialsFlow } = require('@commercetools/sdk-middleware-auth');
const { createHttpMiddleware } = require('@commercetools/sdk-middleware-http');
const fetch = require('node-fetch');

const projectKey = 'your-project-key';
const clientId = 'your-client-id';
const clientSecret = 'your-client-secret';
const scope = 'manage_project:your-project-key';
const authUrl = 'https://auth.europe-west1.gcp.commercetools.com';
const apiUrl = 'https://api.europe-west1.gcp.commercetools.com';

const authMiddleware = createAuthMiddlewareForClientCredentialsFlow({
  host: authUrl,
  projectKey,
  credentials: { clientId, clientSecret },
  fetch,
});

const httpMiddleware = createHttpMiddleware({ host: apiUrl, fetch });

const client = new ClientBuilder().withProjectKey(projectKey)
  .withMiddleware(authMiddleware)
  .withMiddleware(httpMiddleware)
  .build();

const requestBuilder = createRequestBuilder({ projectKey });
const productDraft = {
  name: { en: "Sample Product" },
  slug: { en: "sample-product" },
  productType: { typeId: "product-type", id: "product-type-id" }
};

const uri = requestBuilder.products.build();
const request = {
  uri,
  method: 'POST',
  body: productDraft,
};

client.execute(request)
  .then(response => console.log(response))
  .catch(error => console.error(error));

```
. Postman
Tool: Postman

Purpose: An API client for testing web services. Postman makes it easier to explore commercetools API endpoints and test API requests and responses without writing code.

Coding Example: Using Postman to create a new customer in commercetools.

Set up a new POST request to the commercetools API endpoint for creating customers.
Configure authentication using the OAuth 2.0 settings provided by commercetools.
In the request body, enter the customer details in JSON format.
Send the request and review the response to ensure the customer was created successfully.
. Visual Studio Code
Tool: Visual Studio Code (VS Code)

Purpose: A powerful code editor that supports a wide range of programming languages, including those commonly used with commercetools (JavaScript, TypeScript).

Coding Example: Configuring VS Code with the ESLint plugin to enforce code quality in commercetools projects.

Install the ESLint extension in VS Code.
Configure .eslintrc.json in your project root to define the coding standards.
The ESLint extension will automatically highlight issues in your code as you type, helping to maintain code quality.

. Docker
Tool: Docker

Purpose: Facilitates the creation, deployment, and running of applications by using containers. Docker is invaluable for setting up isolated environments for testing commercetools applications.

Coding Example: Running a commercetools mock server in a Docker container for local testing.

```
# Use an official Node runtime as a parent image
FROM node:14

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy the current directory contents into the container at /usr/src/app
COPY . .

# Install any needed packages specified in package.json
RUN npm install

# Make port 3000 available to the world outside this container
EXPOSE 3000

# Define environment variable
ENV NAME commercetools-mock-server

# Run app.js when the container launches
CMD ["node", "app.js"]

```
Conclusion

Building applications on commercetools is an exciting endeavor, offering developers the opportunity to craft cutting-edge e-commerce solutions. By leveraging the essential tools outlined above—ranging from commercetools' own SDKs and APIs to versatile tools like Postman, VS Code, and Docker—developers can enhance their productivity, streamline development processes, and deliver robust, scalable e-commerce platforms. With these tools in your arsenal and a commitment to best practices, you're well-equipped to take on any commercetools project.
