# OpenMetadata UI
|
|||
|
|
This guide will help you run OpenMetadata UI locally in dev mode.
|
|||
|
|
|
|||
|
|
## Pre-requisites
|
|||
|
|
Before proceeding, ensure that you have installed the node and yarn with the versions given below.
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
"node": ">=10.0.0",
|
|||
|
|
"yarn": "^1.22.0"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Install [Node](https://nodejs.org/en/download/) and [Yarn](https://classic.yarnpkg.com/lang/en/docs/install/).
|
|||
|
|
|
|||
|
|
Install ANTLR using our recipes via
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
sudo make install_antlr_cli
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Using the command below, spin up the server locally from the directory `openmetadata-dist/target/openmetadata-*-SNAPSHOT`.
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
./bin/openmetadata-server-start.sh conf/openmetadata.yaml
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
> Since typescript is heavily used in the OpenMetadata project, we generate the typescript types and the interface from JSON schema. We use the `QuickType` tool to generate the typescript types and interfaces. You can view the complete instructions [here](/developers/contribute/build-code-and-run-tests/generate-typescript-types-from-json-schema).

## Steps to Run OpenMetadata UI
|
|||
|
|
Once the node and yarn are installed in the system, you can perform the following steps to run OpenMetadata UI.
|
|||
|
|
|
|||
|
|
**Step 1**: Run the given command to install the required dependencies.
|
|||
|
|
|
|||
|
|
**Note**: It’s a one-time task to install dependencies. If there are any changes in the `package.json` file, the following steps will have to be performed again.
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
# installing dependencies
|
|||
|
|
> make yarn_install_cache
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**Step 2**: Start the UI locally
|
|||
|
|
|
|||
|
|
```shell
|
|||
|
|
# starting the UI locally
|
|||
|
|
> make yarn_start_dev_ui
|
|||
|
|
```
|
|||
|
|
**Step 3**: Visit [localhost:3000](http://localhost:3000/) to access the OpenMetadata UI.
