# Migrating to v6.x

The following packages have been updated in the release being dubbed as `v6`:

*   `@slack/web-api@6.0.0`
*   `@slack/rtm-api@6.0.0`
*   `@slack/webhook@6.0.0`
*   `@slack/oauth@2.0.0`
*   `@slack/interactive-messages@2.0.0`
*   `@slack/events-api@3.0.0`
*   `@slack/types@2.0.0`
*   `@slack/logger@3.0.0`
*   `@slack/socket-mode@1.0.0`

To migrate to the latest packages, updating your minimum Node.js to `12.13.0` is all that is required, except for `@slack/oauth` which has one additional breaking change. This migration should take less than 15 minutes.

### Minimum Node Version {#minimum-node-version}

Our newly released major versions all require a minimum Node version of `12.13.0` and minimum npm version of `6.12.0`.

Learn more about our [support schedule](https://docs.slack.dev/tools/node-slack-sdk/support-schedule.md) so that you can prepare and plan for future updates.

### Minimum TypeScript Version {#minimum-typescript-version}

Our newly released major versions all require a minimum TypeScript version of `4.1`.

### Org Wide App Installation changes to InstallationStore in @slack/oauth {#org-wide-app-installation-changes-to-installationstore-in-slackoauth}

In [`@slack/oauth@1.4.0`](https://github.com/slackapi/node-slack-sdk/releases/tag/%40slack%2Foauth%401.4.0), we introduced support for [org wide app installations](https://docs.slack.dev/enterprise/organization-ready-apps.md). To add support to your applications, two new methods were introduced to the Installation Store used during OAuth, `fetchOrgInstallation` & `storeOrgInstallation`. With `@slack/oauth@2.0.0`, we have dropped support for these two new methods for a simpler interface. See the code samples below for the recommended changes to migrate.

Before:

```
installationStore: {    storeInstallation: async (installation) => {      // change the line below so it saves to your database      return await database.set(installation.team.id, installation);    },    fetchInstallation: async (installQuery) => {      // change the line below so it fetches from your database      return await database.get(installQuery.teamId);    },    storeOrgInstallation: async (installation) => {      // include this method if you want your app to support org wide installations      // change the line below so it saves to your database      return await database.set(installation.enterprise.id, installation);    },    fetchOrgInstallation: async (installQuery) => {      // include this method if you want your app to support org wide installations      // change the line below so it fetches from your database      return await database.get(installQuery.enterpriseId);    },  },
```

After:

```
installationStore: {    storeInstallation: async (installation) => {      if (installation.isEnterpriseInstall) {        // support for org wide app installation        return await database.set(installation.enterprise.id, installation);      } else {        // single team app installation        return await database.set(installation.team.id, installation);      }      throw new Error('Failed saving installation data to installationStore');    },    fetchInstallation: async (installQuery) => {      // replace database.get so it fetches from your database      if (installQuery.isEnterpriseInstall && installQuery.enterpriseId !== undefined) {        // org wide app installation lookup        return await database.get(installQuery.enterpriseId);      }      if (installQuery.teamId !== undefined) {        // single team app installation lookup        return await database.get(installQuery.teamId);      }      throw new Error('Failed fetching installation');    },  },
```

### Deprecating @slack/events-api & @slack/interactive-messages packages {#deprecating-slackevents-api--slackinteractive-messages-packages}

`@slack/events-api` and `@slack/interactive-messages`are now deprecated and have reached end of life. Development has fully stopped for these packages and all remaining open issues and pull requests have been closed. Bolt for JavaScript can now perform all the same functionality as these packages. We think you’ll love the more modern set of features you get in Bolt. Here are some migration examples:

Before:

```
// @slack/events-apislackEvents.on('app_home_opened', (event) -> {// fired when `app_home_opened` event is received// do work});// @slack/interactive-messagesslackInteractions.action({actionId: 'buttonActionId'}, (payload, respond) => {// fired when a clicked button's actionId matches// do workrespond();});
```

After:

```
// @slack/boltapp.event('app_home_opened', async ({ event }) -> {// fired when `app_home_opened` event is received// do work});// @slack/boltapp.action('buttonActionId', async ({ action, ack }) => {// fired when a clicked button's actionId matches// do workawait ack();});// @slack/bolt also has listeners for options, view, slash commands and shortcuts
```
