Developing A Task Management ChatGPT Plugin with Typescript

Task management is an essential aspect of productivity and organization in both personal and professional settings.

With the rise of virtual assistants and chatbots, integrating task management capabilities into these platforms has become increasingly popular.

In tutorial, we will build ChatGPT plugin using Next.js, leveraging its new functionality and routes. The goal of our plugin is to provide task management capabilities, allowing users to list, , and delete tasks.

Additionally, we will enable querying information about tasks, such as the number of remaining tasks. By the end of this tutorial, you will have a solid understanding of how to develop your own custom plugins.

To keep simple, we will store our task data in memory using a store-like structure. However, in a production application, you would typically use a database for persistent storage. Now, let' dive into the development .

To start with, we will scaffold our application by running : npx -next-app chat-gpt-plugin
Following the prompt and select the appropriate instruction guide like this. choose

Would you like to use TypeScript with this project? …Yes
Would you like to use ESLint with this project? » Yes
Would you like to use Tailwind with this project? » No
Would you like to use src/ with this project? » Yes
Use App Router (recommended)? » Yes
Would you like to customize the default import alias? » Yes
What import alias would you like configured? … @/* – press enter

Following these steps would create our nextjs application.

Now, to start our application, navigate into the newly created chat-gpt-plugin folder and run :
npm run dev

Your application should now be running on http://localhost:3000/. Go to your browser and visit this address.

everything works fine, you should see this Nextjs page in your browser:

Now, let's open the ChatGPT documentation on the OpenAI website and explore the relevant section for our plugin. This documentation will serve as our reference throughout the development process.

Once you have reviewed the documentation, let's return to our application. We need to set up some configurations, starting with the headers to enable (CORS) for the ChatGPT API at Open API Doc

Inside our nextconfig file, in your project folder, add the following code:

Here in this code, we provided a configuration for our application.

The headers function here is an asynchronous function that we set up as custom headers for routes.

We set the Access-Control-Allow-Origin header to allow requests from https://chat.openai.com for all routes matching the /:path* pattern.

This is necessary in order to register our plugin.

Now, inside the public folder create a folder called .well-know. Create a file inside the .well-know directory called -plugin.

The ai-plugin.json is a manifest that provides information about your plugin, such as its name, version, and main configuration endpoint, which can be used by the ChatGPT system to interact with your plugin effectively.

Add the following code to the ai-plugin.json file:

Here in this code we simply provide a JSON object that represents the schema of our Chatgpt plugin.

This JSON object follows the schema defined for chatgpt plugins and provides essential information about the plugin, including its name, description, authentication requirements, API details, logo, contact email, and legal information.

Now let's create the main configuration for our app.

In the public directory, create a file. Name it openapi.yml and add the following code to it :

Here in this code, we
