Contribution Guidelines

Thank you for your interest in contributing to the documentation! You will be helping the open source community and other developers interested in learning more about Medusa and using it.

This guide is specific to contributing to the documentation. If you’re interested in contributing to Medusa’s codebase, check out the contributing guidelines in the Medusa GitHub repository.

Site Setup

The documentation website is built with Docusaurus, a framework that optimizes documentation creation. If you’re not familiar with Docusaurus, it’s recommended to check out the Installation documentation on their website to better understand Docusaurus, how it works, its structure, and more details.

The documentation codebase is hosted as part of the medusa repository on GitHub. You’ll find the code that runs the docusaurus website under the www/docs directory.

---

Documentation Content

The documentation content is written in Markdown format and is located in the docs/content directory of the same repository. If you’re not familiar with Markdown, check out this cheat sheet for a quick start.

You’ll also find MDX files. MDX files combine the power of Markdown with React. So, the content of the file can contain JSX components and import statements, among other features. You can learn more about MDX in docusaurus’s guide.

---

What You Can Contribute To

• You can contribute to the Docusaurus codebase to add a new feature or fix a bug in the documentation website.
• You can contribute to the documentation content either by fixing errors you find or by adding documentation pages.

---

What You Can’t Contribute To

The Services Reference is an automatically generated API reference using Typedoc. So, you can’t contribute to it by making changes to its markdown files.

You can, however, contribute to the script generating it if you find any issues in it.

---

Style Guide

When you contribute to the documentation content, make sure to follow the documentation style guide.

---

How to Contribute

If you’re fixing errors in an existing documentation page, you can scroll down to the end of the page and click on the “Edit this page” link. You’ll be redirected to the GitHub edit form of that page and you can make edits directly and submit a pull request (PR).

If you’re adding a new page or contributing to the codebase, fork the repository, create a new branch, and make all changes necessary in your repository. Then, once you’re done creating a PR in the Medusa repository.

For more details on how to contribute, check out the contribution guidelines in the Medusa repository.

Base Branch

When you make an edit to an existing documentation page or fork the repository to make changes to the documentation, you have to create a new branch.

Documentation contributions always use master as the base branch.

Branch Name

Make sure that the branch name starts with docs/. For example, docs/fix-services.

Pull Request Conventions

When you create a pull request, prefix the title with “docs:”. Make sure to keep “docs” in small letters.

In the body of the PR, explain clearly what the PR does. If the PR solves an issue, use closing keywords with the issue number. For example, “Closes #1333”.

---

Sidebar

When you add a new page to the documentation, you must add the new page in www/docs/sidebars.js under the docsSidebar. You can learn more about the syntax used here.

Terminology

When the documentation page is a conceptual or an overview documentation, the label in the sidebar should start with a noun.

When the documentation page is tutorial documentation, the label in the sidebar should start with a verb. Exceptions to this rule are integration documentation and upgrade guides.

Character Count

The character count of the sidebar item's label must be at most twenty-seven characters. For the API Reference, the sidebar item's label must be at most twenty-five characters.

---

Notes and Additional Information

When displaying notes and additional information on a documentation page, use Admonitions. Make sure the type of admonition used matches the note’s importance to the current document.

If the note is something developers have to be careful of doing or not doing, use the caution or danger admonitions based on how critical it is.

If the note is defining something to the developer in case they’re not familiar with it, use the info admonition.

If the note displays helpful information and tips use the tip admonition.

If the admonition does not match any of the mentioned criteria, always default to the note admonition.

---

Images

If you are adding images to a documentation page, you can host the image on Imgur for free.

Code Blocks

Use Tabs with Code Blocks

To use Tabs with Code Blocks, you have to use Docusaurus's Tabs and TabItem components.

You must also pass to the Tabs component the prop wrapperClassName="code-tabs" to ensure correct styling.

For example:

import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';


<Tabs groupId="request-type" wrapperClassName="code-tabs">
<TabItem value="client" label="Medusa JS Client" default>

```jsx
medusa.admin.uploads.create(file) // file is an instance of File
.then(({ uploads }) => {
  const key = uploads[0].key
})
```

</TabItem>
<TabItem value="curl" label="cURL">

```bash
curl -L -X POST '<YOUR_SERVER>/admin/uploads' \
  -H 'Authorization: Bearer <API_TOKEN>' \
  -H 'Content-Type: text/csv' \
  -F 'files=@"<FILE_PATH_1>"'
```

</TabItem>
</Tabs>

Add Title to Code Block with Tabs

If you want to add a title to a code block with tabs, add the codeTitle prop to the Tabs component.

For example:

<Tabs 
  groupId="request-type"
  wrapperClassName="code-tabs"
  codeTitle="/src/services/hello.ts">

Add Title to Code Block without Tabs

To add a title to a code block without tabs:

```js title=src/index.ts
console.log("hello")
```

Remove Report Button

Some code block don't need a report button. To remove the report button, use the noReport metadata.

For example:

```bash noReport
medusa new my-medusa-store --seed
```

Remove Copy Button

Some code blocks don't need a copy button. To remove the copy button, use the noCopy metadata:

For example:

```bash noCopy
medusa new my-medusa-store --seed
```

---

NPM and Yarn Code Blocks

If you’re adding code blocks that use NPM and Yarn, you must use the npm2yarn syntax.

For example:

```bash npm2yarn
npm run start
```

The code snippet must be written using NPM, and the npm2yarn plugin will automatically transform it to Yarn.

Expand Commands

Don't use commands in their abbreviated terms. For example, instead of npm i use npm install.

Run Command

Make sure to always use the run command when the command runs a script.

For example, even though you can run the start script using NPM with npm start, however, to make sure it’s transformed properly to a Yarn command, you must add the run keyword before start.

Global Option

When a command uses the global option -g, add it at the end of the NPM command to ensure that it’s transformed to a Yarn command properly. For example:

npm

npm install @medusajs/medusa-cli -g

Yarn

yarn global add @medusajs/medusa-cli

Linting with Vale

Medusa uses Vale to lint documentation pages and perform checks on incoming PRs into the repository.

Result of Vale PR Checks

You can check the result of running the "lint" action on your PR by clicking the Details link next to it. You can find there all errors that you need to fix.

Run Vale Locally

If you want to check your work locally, you can do that by:

1. Installing Vale on your machine.
2. Change to the docs directory:

cd docs

3. Run the run-vale script:

./run-vale.sh error

VS Code Extension

To facilitate writing documentation, you can optionally use the Vale VS Code extension. This will show you any errors in your documentation while writing it.

Linter Exceptions

If it's needed to break some style guide rules in a document, you can wrap the parts that the linter shouldn't scan with the following comments in the md or mdx files:

<!-- vale off -->

content that shouldn't be scanned for errors here...

<!-- vale on -->

You can also disable specific rules. For example:

<!-- vale docs.Numbers = NO -->

Medusa supports Node versions 14 and 16.

<!-- vale docs.Numbers = YES -->

If you use this in your PR, you must justify its usage.

---

Linting with ESLint

Medusa uses Eslint to lint code blocks in the documentation and perform checks on incoming PRs into the repository.

Result of ESLint PR Checks

You can check the result of running the "eslint" action on your PR by clicking the Details link next to it. You can find there all errors that you need to fix.

Running ESLint locally

If you want to check your work locally, you can do that by:

1. Installing the dependencies in the root directory:

yarn install

2. Run the lint command:

yarn lint:docs

You can also pass the --fix option to automatically fix errors.

ESLint Exceptions

If some code blocks have errors that can't or shouldn't be fixed, you can add the following command before the code block:

<!-- eslint-skip -->

```js
console.log("This block isn't linted")
```

```js
console.log("This block is linted")
```

You can also disable specific rules. For example:

<!-- eslint-disable semi -->

```js
console.log("This block can use semicolons");
```

```js
console.log("This block can't use semi colons")
```
