A React + AWS Serverless full stack implementation of the 30 example applications found in the official OpenAI API documentation. Now with LangChain!

IMPORTANT DISCLAIMER: AWS' Lambda service has a hard 29-second timeout. OpenAI API calls often take longer than this, in which case the AWS API Gateway endpoint will return a 504 "Gateway timeout error" response to the React client. This happens frequently with apps created using chatgpt-4. Each of the 30 OpenAI API example applications are nonetheless implemented exactly as they are specified in the official documentation.

Complete documentation is located here.

React app that leverages Vite.js, @chatscope/chat-ui-kit-react, and react-pro-sidebar.

• robust, highly customizable chat features
• A component model for implementing your own highly personalized OpenAI apps
• Skinnable UI for each app
• Includes default assets for each app
• Small compact code base
• Robust error handling for non-200 response codes from the custom REST API
• Handles direct text input as well as file attachments
• Info link to the OpenAI API official code sample
• Build-deploy managed with Vite

A REST API implementing each of the 30 example applications from the official OpenAI API Documentation using a modularized Terraform approach. Leverages OpenAI's suite of AI models, including GPT-3.5, GPT-4, DALL·E, Whisper, Embeddings, and Moderation.

• Built on the OpenAI API Python Library
• LangChain enabled API endpoints where designated.
• Customizable. Modularized endpoints that only take a few lines of code each.
• Highly secure. Your OpenAI API key is stored in a local .env file, and is kept safe during development, build and deployment to production.
• Implements excellent CloudWatch logs for Lambda as well as API Gateway
• Fully automated and parameterized Terraform build
• well documented code plus supplemental documentation resources as well as detailed documentation on each URL endpoint.
• Low-cost AWS serverless implementation using AWS API Gateway and AWS Lambda; free or nearly free in most cases
• Robust, performant and infinitely scalable
• Fast build time; usually less than 60 seconds to fully implement
• Includes both Python and Node.js Lambda examples
• Deploy https to a custom domain
• Preconfigured Postman files for testing
• includes AWS API Gateway usage policy and api key
• Full CORS configuration

• AWS account
• AWS Command Line Interface
• Terraform. If you're new to Terraform then see Getting Started With AWS and Terraform
• OpenAI platform API key. If you're new to OpenAI API then see How to Get an OpenAI API Key
• Python 3.11: for creating virtual environment used for building AWS Lambda Layer, and locally by pre-commit linters and code formatters.
• NodeJS: used with NPM for local ReactJS developer environment, and for configuring/testing Semantic Release.
• Docker Compose: used by an automated Terraform process to create the AWS Lambda Layer for OpenAI and LangChain.

Detailed documentation for each endpoint is available here: Documentation

• Automated Pull Requests: Github Actions are triggered on pull requests to run any of several different kinds of technology-specific unit tests depending on the contents of the commits included in the PR.
• python-dotenv for storing sensitive data for local development
• .gitignore ensures that no sensitive nor useless data accidentally gets pushed to GitHub.
• tox.ini file for configuring behaviors of Python testing tools
• GitHub Actions automates unit testing, semantic release rule checking, and dependabot actions.
• GitHub Secrets to provide sensitive data to Github Actions workflows
• GitHub Issues
• Makefile automates procedures like init, build, test, release and linting for Python, ReactJS and Terraform.
• pre-commit automatically enforces a multitude of code quality, coding style and security policies.
• Dependabot automatically updates the version pins of code library dependencies for Python, ReactJS and Terraform.
• Unit Tests are automated and can be invoked
  • manually from the command line
  • manually from GitHub Actions
  • automatically by Dependabot.
• Mergify automates processing of bot-created pull requests
• Semantic Release automates version releases as well as maintains the change log for the repo.

Linters and formatters are tools used in programming to analyze and improve the quality of code. This project leverages several, including:

• Prettier: an opinionated code formatter that supports many file formats and languages. This project leverages Prettier to standardize formatting of md, css, json, yml, js, jsx and Typescript files.
• Black: an opinionated code formatter for Python which is compatible with PEP 8 and the Python Style Guide.
• isort: a Python utility that sorts imports alphabetically, and automatically, separated into sections and by type.

• ESLint: an open source project that helps you find and fix problems with your JavaScript and JSX code.
• Flake8: provides Python syntax checking, naming style enforcement, code style enforcement, and cyclomatic complexity analysis.
• pylint: a static code analyser for Python. It analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored.
• bandit: a tool designed to find common security issues in Python code.

• pre-commit Hooks: scripts that run automatically before each commit is made to a repository, checking your code for embedded passwords, errors, issues, and any of a multitude of configurable policies that you can optionally enforce. They're part of the git hooks system, which allows you to trigger actions at certain points in git's execution. This project uses many Hooks. See pre-commit-config.yaml.
• codespell: fixes common misspellings in text files. It's designed primarily for checking misspelled words in source code, but it can be used with other files as well.
