Native Apps
2 minute read
Introduction
Snowflake Native Apps are applications built and executed directly within the Snowflake Data Cloud platform. These apps can be used to extend the capabilities of Snowflake by integrating with external services, automating workflows, and building custom data applications. These apps are developed using Snowflake-native tools (e.g., Snowflake SQL, Snowflake API, and JavaScript) and can be distributed on the Snowflake Marketplace.
The Snowflake emulator supports creating & deploying Native Apps locally with the same statements as the Snowflake service. The following operations are supported:
CREATE APPLICATIONS
SHOW APPLICATION PACKAGES
ALTER APPLICATION PACKAGE
DESCRIBE APPLICATION
DROP APPLICATION PACKAGE
Getting started
This guide is designed for users new to Native Apps and assumes basic knowledge of Snow CLI and Snowflake. Start your Snowflake emulator and connect to it using the Snow CLI in order to execute the commands further below.
In this guide, you will locally deploy a Native App using an existing Application Package.
Clone the repository
Clone the Native Apps repository and navigate to the tasks-streams
directory:
git clone https://github.com/snowflakedb/native-apps-examples.git
cd native-apps-examples/tasks-streams
Deploy Native App
Deploy the Native App using the Snow CLI:
snow app run --connection localstack
The following output should be displayed:
Creating new application package tasks_streams_app_pkg_username in account.
Checking if stage tasks_streams_app_pkg_username.app_src.stage exists, or creating a new one if none exists.
Performing a diff between the Snowflake stage: stage and your local deploy_root: /Users/username/code/localstack/native-apps-examples/tasks-streams/output/deploy.
Local changes to be deployed:
added: app/manifest.yml -> manifest.yml
added: app/setup_script.sql -> setup_script.sql
added: src/module-ui/src/environment.yml -> streamlit/environment.yml
added: src/module-ui/src/ui.py -> streamlit/ui.py
Updating the Snowflake stage from your local /Users/username/code/localstack/native-apps-examples/tasks-streams/output/deploy directory.
Validating Snowflake Native App setup script.
Creating new application object tasks_streams_app_username in account.
Application 'TASKS_STREAMS_APP_username' created successfully.
Your application object (tasks_streams_app_username) is now available:
https://app.snowflake.com/test/test/#/apps/application/TASKS_STREAMS_APP_username
Access Native App
You can access the Native App by visiting your preferred browser and navigating to the following URL:
https://snowflake.localhost.localstack.cloud:4566/apps/test/test/TASKS_STREAMS_APP_username/
Note
The URL above is an example. Change the outputted URL by:
- Replacing
https://app.snowflake.com
withhttps://snowflake.localhost.localstack.cloud:4566
. - Changing the path structure from
/#/apps/application/
to/apps/test/test/
.
You can make additional changes depending on your local setup.
The following app should be displayed:
