# gatsby-plugin-robots-txt
> Create `robots.txt` for your Gatsby site on build.
## Install
`yarn add gatsby-plugin-robots-txt`
or
`npm install --save gatsby-plugin-robots-txt`
## How To Use
`gatsby-config.js`
```js
module.exports = {
siteMetadata: {
siteUrl: 'https://www.example.com'
},
plugins: ['gatsby-plugin-robots-txt']
};
```
## Options
This plugin uses [`generate-robotstxt`](https://github.com/itgalaxy/generate-robotstxt#usage) to generate content
of `robots.txt` and it has the following options:
| Name | Type | Default | Description |
| :----------: | :--------: | :-----------------------------------: | :----------------------------------------------------------------------------: |
| `host` | `String` | `${siteMetadata.siteUrl}` | Host of your site |
| `sitemap` | `String` / `String[]` | `${siteMetadata.siteUrl}/sitemap-index.xml` | Path(s) to `sitemap.xml` |
| `policy` | `Policy[]` | `[]` | List of [`Policy`](https://github.com/itgalaxy/generate-robotstxt#usage) rules |
| `configFile` | `String` | `undefined` | Path to external config file |
| `output` | `String` | `/robots.txt` | Path where to create the `robots.txt` |
`gatsby-config.js`
```js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
host: 'https://www.example.com',
sitemap: 'https://www.example.com/sitemap.xml',
policy: [{userAgent: '*', allow: '/'}]
}
}
]
};
```
### `env`-option
`gatsby-config.js`
```js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
host: 'https://www.example.com',
sitemap: 'https://www.example.com/sitemap.xml',
env: {
development: {
policy: [{userAgent: '*', disallow: ['/']}]
},
production: {
policy: [{userAgent: '*', allow: '/'}]
}
}
}
}
]
};
```
The `env` key will be taken from `process.env.GATSBY_ACTIVE_ENV` first (
see [Gatsby Environment Variables](https://www.gatsbyjs.org/docs/environment-variables/) for more information on this
variable), falling back to `process.env.NODE_ENV`. When this is not available then it defaults to `development`.
You can resolve the `env` key by using `resolveEnv` function:
`gatsby-config.js`
```js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
host: 'https://www.example.com',
sitemap: 'https://www.example.com/sitemap.xml',
resolveEnv: () => process.env.GATSBY_ENV,
env: {
development: {
policy: [{userAgent: '*', disallow: ['/']}]
},
production: {
policy: [{userAgent: '*', allow: '/'}]
}
}
}
}
]
};
```
### `configFile`-option
You can use the `configFile` option to set specific external configuration:
`gatsby-config.js`
```js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
configFile: 'robots-txt.config.js'
}
}
]
};
```
`robots-txt.config.js`
```js
module.exports = {
host: 'https://www.example.com',
sitemap: 'https://www.example.com/sitemap.xml',
policy: [{userAgent: '*'}]
};
```
#### Netlify
If you would like to disable crawlers
for [deploy-previews](https://www.netlify.com/blog/2016/07/20/introducing-deploy-previews-in-netlify/) you can use the
following snippet:
`gatsby-config.js`
```js
const {
NODE_ENV,
URL: NETLIFY_SITE_URL = 'https://www.example.com',
DEPLOY_PRIME_URL: NETLIFY_DEPLOY_URL = NETLIFY_SITE_URL,
CONTEXT: NETLIFY_ENV = NODE_ENV
} = process.env;
const isNetlifyProduction = NETLIFY_ENV === 'production';
const siteUrl = isNetlifyProduction ? NETLIFY_SITE_URL : NETLIFY_DEPLOY_URL;
module.exports = {
siteMetadata: {
siteUrl
},
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
resolveEnv: () => NETLIFY_ENV,
env: {
production: {
policy: [{userAgent: '*'}]
},
'branch-deploy': {
policy: [{userAgent: '*', disallow: ['/']}],
sitemap: null,
host: null
},
'deploy-preview': {
policy: [{userAgent: '*', disallow: ['/']}],
sitemap: null,
host: null
}
}
}
}
]
};
```
### `query`-option
By default the site URL will come from the Gatsby node `site.siteMeta.siteUrl`. Like
in [Gatsby's sitemap plugin](https://www.gatsbyjs.org/packages/gatsby-plugin-sitemap/) an optional GraphQL query can be
used to provide a different value from another data source as long as it returns the same shape:
`gatsby-config.js`
```js
module.exports = {
plugins: [
{
resolve: 'gatsby-plugin-robots-txt',
options: {
query: `{
site: MyCustomDataSource {
siteMetadata {
siteUrl
}
}
}`
}
}
]
};
```
