We offer both cloud and open-source solutions to cater to different needs. + +## 1. Installation + +For the open-source version, you can install the Mem0 package using npm: + +```bash +npm i mem0ai +``` + +## 2. API Key Setup + +For the cloud offering, sign in to [Mem0 Platform](https://app.mem0.ai/dashboard/api-keys) to obtain your API Key. + +## 3. Client Features + +### Cloud Offering + +The cloud version provides a comprehensive set of features, including: + +- **Memory Operations**: Perform CRUD operations on memories. +- **Search Capabilities**: Search for relevant memories using advanced filters. +- **Memory History**: Track changes to memories over time. +- **Error Handling**: Robust error handling for API-related issues. +- **Async/Await Support**: All methods return promises for easy integration. + +### Open-Source Offering + +The open-source version includes the following top features: + +- **Memory Management**: Add, update, delete, and retrieve memories. +- **Vector Store Integration**: Supports various vector store providers for efficient memory retrieval. +- **LLM Support**: Integrates with multiple LLM providers for generating responses. +- **Customizable Configuration**: Easily configure memory settings and providers. +- **SQLite Storage**: Use SQLite for memory history management. + +## 4. Memory Operations + +Mem0 provides a simple and customizable interface for performing memory operations. You can create long-term and short-term memories, search for relevant memories, and manage memory history. + +## 5. Error Handling + +The MemoryClient throws errors for any API-related issues. You can catch and handle these errors effectively. + +## 6. Using with async/await + +All methods of the MemoryClient return promises, allowing for seamless integration with async/await syntax. + +## 7. Testing the Client + +To test the MemoryClient in a Node.js environment, you can create a simple script to verify the functionality of memory operations. + +## Getting Help + +If you have any questions or need assistance, please reach out to us: + +- Email: founders@mem0.ai +- [Join our discord community](https://mem0.ai/discord) +- [Join our slack community](https://mem0.ai/slack) +- GitHub Issues: [Report bugs or request features](https://github.com/mem0ai/mem0ai-node/issues) diff --git a/mem0-ts/jest.config.js b/mem0-ts/jest.config.js new file mode 100644 index 00000000..ce23df67 --- /dev/null +++ b/mem0-ts/jest.config.js @@ -0,0 +1,29 @@ +/** @type {import('ts-jest').JestConfigWithTsJest} */ +module.exports = { + preset: "ts-jest", + testEnvironment: "node", + roots: ["/src", "/tests"], + testMatch: [ + "**/__tests__/**/*.+(ts|tsx|js)", + "**/?(*.)+(spec|test).+(ts|tsx|js)", + ], + transform: { + "^.+\\.(ts|tsx)$": [ + "ts-jest", + { + tsconfig: "tsconfig.test.json", + }, + ], + }, + moduleNameMapper: { + "^@/(.*)$": "/src/$1", + }, + setupFiles: ["dotenv/config"], + testPathIgnorePatterns: ["/node_modules/", "/dist/"], + moduleFileExtensions: ["ts", "tsx", "js", "jsx", "json", "node"], + globals: { + "ts-jest": { + tsconfig: "tsconfig.test.json", + }, + }, +};
