+# AdonisJS package starter kit
+
+> A boilerplate for creating AdonisJS packages
+
+This repo contains the default folder structure, development, and peer dependencies to create a package for AdonisJS v6.
+
+You can create a package from scratch with your folder structure and workflow. However, using a default starter kit can speed up the process, as you have fewer decisions to make.
+
+## Folder structure
+
+The starter kit mimics the folder structure of the official packages. Feel free to rename files and folders as per your requirements.
+
+```
+├── providers
+├── src
+├── stubs
+├── index.ts
+├── LICENSE.md
+├── package.json
+├── README.md
+└── tsconfig.json
+```
+
+- The `providers` directory is used to store service providers.
+- The `src` directory contains the source code of the package. All business logic should be inside this folder.
+- The `stubs` directory is used to keep scaffolding stubs. You might copy some stubs to the user application once they configure the package.
+- The `index.ts` file is the main entry point of the package.
+
+### File system naming convention
+
+We use `snake_case` naming conventions for the file system. The rule is enforced using ESLint. However, feel free to disable the rule and use your preferred naming conventions.
+
+## Peer dependencies
+
+The starter kit has a peer dependency on `@adonisjs/core@6`. Since you are creating a package for AdonisJS, you must make it against a specific version of the framework core.
+
+If your package needs Lucid to be functional, you may install `@adonisjs/lucid` as a development dependency and add it to the list of `peerDependencies`.
+
+As a rule of thumb, packages installed in the user application should be part of the `peerDependencies` of your package and not the main dependency.
+
+For example, if you install `@adonisjs/core` as a main dependency, then essentially, you are importing a separate copy of `@adonisjs/core` and not sharing the one from the user application. Here is a great article explaining [peer dependencies](https://blog.bitsrc.io/understanding-peer-dependencies-in-javascript-dbdb4ab5a7be).
+
+## Published files
+
+Instead of publishing all the source code of your repo to npm, you must cherry-pick files and folders to publish only the required files.
+
+The cherry-picking is done using the `files` property inside the `package.json` file. By default, we publish the following files and folders.
+
+```json
+{
+  "files": [
+    "src",
+    "providers",
+    "index.ts",
+    "build/src",
+    "build/providers",
+    "build/stubs",
+    "build/index.d.ts",
+    "build/index.d.ts.map",
+    "build/index.js"
+  ]
+}
+```
+
+If you notice, we are publishing both the source code (written in TypeScript) and the compiled output (JavaScript) to npm.
+
+- The JavaScript runtime requires compiled output. So that is something you will have to publish.
+- Publishing source code is optional. However, if you generate [declaration maps](https://www.typescriptlang.org/tsconfig#declarationMap), then the TypeScript language server (used by code editors like VSCode) will be able to jump to the actual source code when you perform `CTRL + CLICK`.
+
+If you create additional folders or files, mention them inside the `files` array.
+
+## Exports
+
+[Node.js Subpath exports](https://nodejs.org/api/packages.html#subpath-exports) allows you to define the exports of your package regardless of the folder structure. This starter kit defines the following exports.
+
+```json
+{
+  "exports": {
+    ".": "./build/index.js",
+    "./types": "./build/src/types.js"
+  }
+}
+```
+
+- The dot `.` export is the main export.
+- The `./types` exports all the types defined inside the `./build/src/types.js` file (the compiled output).
+
+Feel free to change the exports as per your requirements.
+
+## Testing
+
+We configure the [Japa test runner](https://japa.dev/) with this starter kit. Japa is used in AdonisJS applications as well. Just run one of the following commands to execute tests.
+
+- `npm run test`: This command will first lint the code using ESlint and then run tests and report the test coverage using [c8](https://github.com/bcoe/c8).
+- `npm run quick:test`: Runs only the tests without linting or coverage reporting.
+
+The starter kit also comes with a Github workflow file to run tests using Github Actions. The tests are executed against `Node.js 18.x` and `Node.js 19.x` versions on both Linux and Windows. Feel free to edit the workflow file in the `.github/workflows` directory.
+
+## TypeScript workflow
+
+- The starter kit uses [tsc](https://www.typescriptlang.org/docs/handbook/compiler-options.html) for compiling the TypeScript to JavaScript at the time of publishing the package.
+- [TS-Node](https://typestrong.org/ts-node/) and [SWC](https://swc.rs/) are used to run tests without compiling the source code.
+- The `tsconfig.json` file is extended from [`@adonisjs/tsconfig`](https://github.com/adonisjs/tooling-config/tree/main/packages/typescript-config) and uses `NodeNext` module system. Meaning the packages are written using ES modules.
+- You can perform type checking without compiling the source code using `npm run typecheck` script.
+
+Feel free to explore the `tsconfig.json` file for all the configured options.
+
+## ESLint and Prettier setup
+
+The starter kit configures ESLint and Prettier. The configuration for both is stored within the `package.json` file, and use our [shared config](https://github.com/adonisjs/tooling-config/tree/main/packages). Feel free to change the config, use custom plugins or remove both tools altogether.
+
+## Using Stale bot (optional)
+
+The [Stale bot](https://github.com/apps/stale) is a Github application that automatically marks issues and PRs as stale and closes after a certain duration of inactivity.
+
+You may optionally configure it at the time of scaffolding the package.
+
+## Unconfigurable bits
+
+- **License**: The `LICENSE.md` file and the `license` property inside the `package.json` file are set to `MIT`. You can change them manually.
+- **Editorconfig**: The `.editorconfig` file is used to define the formatting rules.
+- **No package-lock file**: The `.npmrc` file is created with the rule to diable `package-lock.json` file. Feel free to revert the setting or use a different package manager.
