## Prerequisites
- Node.js **18+**
- pnpm (`npm install -g pnpm`)
## Setup
From the `node/` directory:
```bash
pnpm install
```
## Running the CLI
There are two ways to run the CLI during development:
### Option 1: Development mode (no build needed)
Uses `tsx` to run TypeScript directly. Pass CLI arguments after `pnpm dev`:
```bash
pnpm dev --help
pnpm dev version
pnpm dev add "test memory" --user-id alice
pnpm dev search "test" --user-id alice
pnpm dev config show
```
> **Note:** Do NOT use `pnpm dev -- --help`. With pnpm, arguments pass through directly — adding `--` inserts a literal `--` that breaks the CLI parser.
### Option 2: Build and run compiled JS
```bash
# Build first
pnpm build
# Run the compiled CLI
node dist/index.js --help
node dist/index.js version
node dist/index.js add "test memory" --user-id alice
```
### Option 3: Link globally (makes `mem0` available system-wide)
```bash
pnpm build
pnpm link --global
# Now use it like a normal CLI
mem0 --help
mem0 version
```
> **Warning:** If you also have the Python CLI installed, both register the `mem0` command. The last one linked/installed wins. Unlink with `pnpm unlink --global`.
## Build
```bash
pnpm build
```
The compiled output is in `dist/`.
## Run tests
```bash
# Run all tests
pnpm test
# Watch mode
pnpm test:watch
```
## Lint
```bash
# Check
pnpm lint
# Auto-fix
pnpm lint:fix
```
## Type checking
```bash
pnpm typecheck
```
