## Development Setup

You will need to setup the `supertokens-core` in order to to run the `supertokens-node` tests, you can setup `supertokens-core` by following this [guide](https://github.com/supertokens/supertokens-core/blob/master/CONTRIBUTING.md#development-setup)  
**Note: If you are not contributing to the `supertokens-core` you can skip steps 1 & 4 under Project Setup of the `supertokens-core` contributing guide.**

### Prerequisites

-   OS: Linux or macOS
-   Nodejs & npm
-   IDE: [VSCode](https://code.visualstudio.com/download)(recommended) or equivalent IDE

### Project Setup

1. Fork the [supertokens-node](https://github.com/supertokens/supertokens-node) repository
2. Clone the forked repository in the parent directory of the previously setup `supertokens-root`.  
   `supertokens-node` and `supertokens-root` should exist side by side within the same parent directory
3. `cd supertokens-node`
4. Install the project dependencies  
   `npm i -d`
5. Install the dependencies inside `test/with-typescript`  
   `cd test/with-typescript && npm i && cd ../..`
6. Add git pre-commit hooks  
   `npm run set-up-hooks`

## Modifying Code

1. Open the `supertokens-node` project in your IDE and you can start modifying the code
2. After modifying the code, build your project to implement your changes  
   `npm run build-pretty`

## Testing

1. Navigate to the `supertokens-root` repository
2. Start the testing environment  
   `./startTestingEnv --wait`
3. Navigate to the `supertokens-node` repository  
   `cd ../supertokens-node/`
4. Run all tests (make sure to have node version >= 16.20.0 and < 17.0.0)
   `INSTALL_PATH=../supertokens-root npm test`
5. If all tests pass the output should be:  
   ![node tests passing](https://github.com/supertokens/supertokens-logo/blob/master/images/supertokens-node-tests-passing.png)
6. Navigate to the `test-server` folder within the `supertokens-node` project:
   `cd ./test/test-server/`
7. Install the project dependencies:  
   `npm install`
8. Start the server:
   `npm run start`
9. In the `supertokens-node` root folder, open the `frontendDriverInterfaceSupported.json` file and note the latest version supported. This version will be used to check out the correct version of the `backend-sdk-testing` project.
10. Fork the [backend-sdk-testing](https://github.com/supertokens/backend-sdk-testing) repository.
11. Clone your forked repository into the parent directory of the `supertokens-root` project. Both `supertokens-root` and `backend-sdk-testing` should exist side by side within the same parent directory.
12. Change to the `backend-sdk-testing` directory:
    `cd backend-sdk-testing`
13. Check out the supported FDI version to be tested (as specified in `frontendDriverInterfaceSupported.json`):
    `git checkout <FDI-version>`
14. Install dependencies and build the project:
    `npm install && npm run build-pretty`
15. Run all tests (make sure to have node version >= 16.20.0 and < 17.0.0):
    `INSTALL_PATH=../supertokens-root npm test`

### To be able to run and debug tests from vscode

1. Install the extension - https://marketplace.visualstudio.com/items?itemName=hbenl.vscode-mocha-test-adapter
2. Add the following to your vscode settings:
    ```json
    {
        // ...,
        "mochaExplorer.env": {
            "TEST_MODE": "testing",
            "INSTALL_PATH": "../supertokens-root"
        }
    }
    ```
3. In `lib/tsconfig.json`, change `"sourceMap"` to `true`
4. Run `npm run build`

You should now be able to see tests on the VSCode's testing panel and run/debug from there.

## Implementing RecipeInterfaces

-   Make sure all CRUD operations are available on the objects of that recipe
-   Make sure the implementation of that interface takes types imports from the `index.ts` file of that recipe. This is so that if a user wants to copy / paste that code into their project, they can do so via the normal import statement.

## Implementing APIInterfaces

-   Make sure the implementation of that interface takes types imports from the `index.ts` file of that recipe. This is so that if a user wants to copy / paste that code into their project, they can do so via the normal import statement.

## Generating docs

This will generate the API docs in a folder called `docs`

```
npm run build-docs
```
