# Install Medusa Backend
|
|
|
|
This document will guide you through setting up your Medusa backend in a three steps.
|
|
|
|
## Prerequisites
|
|
|
|
Before you can install and use Medusa, you need the following tools installed on your machine:
|
|
|
|
- [Node.js v16+](./prepare-environment.mdx#nodejs)
|
|
- [Git](./prepare-environment.mdx#git)
|
|
- [PostgreSQL](./prepare-environment.mdx#postgresql)
|
|

## Create a Medusa Backend
|
|
|
|
:::tip
|
|
|
|
It is recommended to use [Yarn](https://yarnpkg.com/getting-started/install) for the installation process as it's much faster than using NPM.
|
|
|
|
:::
|
|
|
|
### 1. Install Medusa CLI
|
|
|
|
To install the Medusa backend, you need Medusa's CLI tool. You can install it globally or, alternatively, use it through npx with `npx @medusajs/medusa-cli <command>`.
|
|
|
|
```bash npm2yarn
|
|
npm install @medusajs/medusa-cli -g
|
|
```
|
|
|
|
:::note
|
|
|
|
If you run into any errors while installing the CLI tool, check out the [troubleshooting guide](../../troubleshooting/cli-installation-errors.mdx).
|
|
|
|
:::
|
|
|
|
### 2. Create a new Medusa project
|
|
|
|
```bash noReport
|
|
medusa new my-medusa-store # or npx @medusajs/medusa-cli new
|
|
```
|
|
|
|
You'll then be asked to specify your PostgreSQL database credentials. You can choose "Continue" to use the default credentials shown in the terminal, choose "Change credentials" to specify your PostgreSQL credentials, or choose "Skip database setup" to create the database later.
|
|
|
|
:::warning
|
|
|
|
If you choose "Skip database setup" you will need to [set the database configurations](../../references/medusa_config/interfaces/medusa_config.ConfigModule.mdx) and [run migrations](../entities/migrations/overview.mdx#migrate-command) later.
|
|
|
|
:::
|
|
|
|
### 3. Start your Medusa backend
|
|
|
|
:::note
|
|
|
|
Make sure your PostgreSQL server is running before you run the Medusa backend.
|
|
|
|
:::
|
|
|
|
```bash noReport
|
|
cd my-medusa-store
|
|
medusa develop # or npx medusa develop
|
|
```
|
|
|
|
After these three steps and in only a couple of minutes, you now have a complete commerce engine running locally. You can test it out by sending a request using a tool like Postman or through the command line:
|
|
|
|
```bash noReport
|
|
curl localhost:9000/store/products
|
|
```
|
|
|
|
<Feedback
|
|
event="survey_server_quickstart"
|
|
question="Did you set up the backend successfully?"
|
|
positiveQuestion="Is there anything that should improved?"
|
|
negativeQuestion="Please describe the issue you faced."

|
|
|
|
## Seed Data
|
|
|
|
For better testing, you can add demo data to your Medusa backend by running the seed command in your Medusa backend directory:
|
|
|
|
```bash
|
|
medusa seed --seed-file=data/seed.json
|
|
# or npx medusa seed --seed-file=data/seed.json
|
|
```
|

|
|
|
|
## Health Route
|
|
|
|
You can access `/health` to get health status of your backend.
