Thank you for your interest in contributing to Couchbase starter kits! This guide will help you understand how to contribute new starter kits for various frameworks.
Please review the Contributing section briefly to understand the process of contributing new starter kits. When you are ready to get started, this README and the accompanying sample files will help you create a new starter kit.
| Framework | Repository Link |
|---|---|
| Spring | Spring Starter Kit |
| Rails | Rails Starter Kit |
Want to create a new starter kit for a framework or language not listed above? Check out the currently requested starter kits in the Issues section. If you don't see the framework or language you are interested in, feel free to open a new Issue and let us know what you would like to contribute.
| Framework | Repository Link |
|---|---|
| Node.js | Node.js Starter Kit |
| Variable Name | Description | Default value |
|---|---|---|
| SPRING_APPLICATION_NAME | The name of your application, used for OTLP as well | couchbase-spring-starter |
| SPRING_COUCHBASE_CONNECTION_STRING | A couchbase connection string | - |
| SPRING_COUCHBASE_USERNAME | Username for authentication with Couchbase | - |
| SPRING_COUCHBASE_PASSWORD | Password for authentication with Couchbase | - |
| COUCHBASE_USE_CAPELLA | Use to change the connection profile | false |
| COUCHBASE_DEFAULT_BUCKET | The name of the Couchbase Bucket, parent of the scope | default |
| COUCHBASE_DEFAULT_SCOPE | The name of the Couchbase scope, parent of the collection | _default |
| COUCHBASE_DEFAULT_COLLECTION | The name of the Couchbase collection to store the Documents | _default |
| COUCHBASE_OTLP_ENABLED | Enable traces and metrics OTLP export | false |
| COUCHBASE_OTLP_ENDPOINT | The OTLP server endpoint to send metrics and traces | - |
Each starter kit should include the following basic functionalities:
Each starter kit should include the following files, and you can find examples of these in the samples directory that you can use in your repository:
README.md: A README file that includes instructions on how to run the starter kit.LICENSE: A license file that includes the license for the starter kit.CODE_OF_CONDUCT.md: A code of conduct file that includes the code of conduct for the starter kit..env.sample: A sample environment file that includes the necessary environment variables for the starter kit..gitpod.yml: A Gitpod configuration file that deploys the starter kit in Gitpod..devcontainer/devcontainer.json: A GitHub Codespaces configuration file that deploys the starter kit in GitHub Codespaces.Adding tests to verify the connection to Couchbase is required, and you can do so either by using the sample GitHub Action workflow or by creating your own test. Read more on testing in the Testing section.
If you are using the sample GitHub Action workflow, you should include the following files in your repository:
.github/workflows/test-couchbase.yml: A GitHub Action workflow that tests the connection to Couchbase.scripts/dbSetup.nu: A database setup script that creates the necessary buckets, scopes, and collections in Couchbase.To ensure your starter kit works correctly, you should include tests that verify the connection to Couchbase. The sample workflow can be used to test the connection to Couchbase.
The workflow should be modified to include the necessary environment variables for your starter kit:
COUCHBASE_DEFAULT_BUCKET variable should be unique, the convention is to prepend the bucket name with the framework name, such as spring_, rails_, or python_.Set up JDK and Setup Gradle steps should be modified to match the build tools for your specific framework.The secrets used in the workflow are stored at the couchbase-starter-kit GitHub organization level, so there is no need to create them in your repository, once your starter kit repository is added to this organization. While you are building it, you can create repository-level secrets in your repository for testing purposes.
The workflow is added to the .github/workflows directory in your repository and can be named test-connection.yml or similar. Make sure to include the database setup script, dbSetup.nu, in a scripts/ directory in the root level of your repository, if you choose to use the sample workflow.
Alternatively, you can build your own test in the testing framework of your choice appropriate for the language or framework you are using inside your starter kit. If you choose to do this, make sure to include the necessary instructions in the README file, and add a GitHub Action workflow that runs the test from your codebase.
The starter kit should be ready to deploy in any number of environments. At a minimum, the starter kit should be deployable in Gitpod, and GitHub Codespaces. See the sample README to be included in your repository to view the Gitpod and GitHub Codespaces buttons that are added to the top of the README.
The sample configuration for Gitpod can be found in the samples/.gitpod.yml file. This file should be included in the root of your repository.
The sample configuration for GitHub Codespaces can be found in the samples/.devcontainer/devcontainer.json file. This file, along with the accompanying postCreate.sh and postStart.sh shell scripts, should be included in the .devcontainer directory in the root of your repository.
Watch this video to see how to get started using GitHub Codespaces to experiment with a Couchbase starter kit all within the virtual environment.

The best way to get started is by looking at the open Issues in this repository. If you see a framework or language that you are familiar with, feel free to contribute a starter kit for that framework.
What about frameworks or languages not mentioned in the open Issues? Feel free to open a new Issue and let us know what you would like to contribute. The team will be happy to review, provide feedback and guidance, and help you get started.
