# Installation

We provide SDKs for developing projects in: NodeJS, Go, React Native (Android and iOS), Web projects (both websites and browser extensions), and Kotlin for Android.

## NodeJS, React Native and Web

The Sodot TypeScript SDKs are published to the Sodot [JFrog Artifactory](https://repo.sodot.dev/) repository.

:::warning[npm registry being retired on 2026-08-01]
The `@sodot/*` packages will be removed from the public npm registry on **2026-08-01**. Use the **Sodot JFrog Artifactory** option below: the legacy npm option is kept for reference and will stop working on that date.
:::

To use the SDK in an existing project:

1. Obtain an Artifactory access token (or, until 2026-08-01, an NPM auth token) and an `API_KEY` from the [Sodot team](mailto\:sdk@sodot.dev).

2. Create a `.npmrc` file in your project's root directory (the same directory as your `package.json` file), and pick **one** of the following options:

<Tabs stateKey="sodot-registry">
  <Tab title="Sodot JFrog Artifactory (recommended)">
    First, generate an Artifactory access token:

    1. Sign in to the [Sodot JFrog Artifactory](https://repo.sodot.dev/) using the **sodot-auth** option.
    2. From the user menu in the top right corner, click **Set Me Up** → **npm** → select the **sodot-npm** repository.
    3. Click the **Generate Token & Create Instructions** button and copy the generated token. (The token is valid for one year. Regenerate it before it expires to avoid service disruptions.)

    Then paste the following into your `.npmrc`:

    ```ini
    @sodot:registry=https://repo.sodot.dev/artifactory/api/npm/sodot-npm/
    //repo.sodot.dev/artifactory/api/npm/sodot-npm/:_authToken=${ARTIFACTORY_TOKEN}
    ```

    And export the token you generated:

    ```bash
    export ARTIFACTORY_TOKEN="<YOUR_TOKEN>"
    ```
  </Tab>

  <Tab title="npm (deprecated, stops working 2026-08-01)">
    Paste the following into your `.npmrc`:

    ```ini
    @sodot:registry=https://registry.npmjs.org/
    //registry.npmjs.org/:_authToken=${NPM_TOKEN}
    ```

    Then export your npm token:

    ```bash
    export NPM_TOKEN="npm_<YOUR_TOKEN>"
    ```
  </Tab>
</Tabs>

3. Add it to your project:

<Tabs>
  <Tab title="Web">
    ```bash
    $ yarn add @sodot/sodot-web-sdk
    ```
  </Tab>
</Tabs>

You can now start generating keys and signing.
