Babel Plugin for React Native
The @datadog/mobile-react-native-babel-plugin enhances the Datadog React Native SDK by automatically enriching React components with contextual metadata. This helps improve the accuracy of features such as RUM Action tracking and Session Replay.
Setup
Note: Make sure you've already integrated the Datadog React Native SDK.
To install with NPM, run:
npm install @datadog/mobile-react-native-babel-plugin
To install with Yarn, run:
yarn add @datadog/mobile-react-native-babel-plugin
Configure Babel
Add the plugin to your Babel configuration. Depending on your setup, you might be using a babel.config.js, .babelrc, or similar.
Example configuration:
module.exports = {
presets: ['module:@react-native/babel-preset'],
plugins: ['@datadog/mobile-react-native-babel-plugin'] // <-- Add here
};
Configuration Options
You can configure the plugin to adjust how it processes your code, giving you control over its behavior and allowing you to tailor it to your project’s needs.
Top-level options
| Option | Type | Default | Description |
|---|---|---|---|
actionNameAttribute | string | – | The chosen attribute name to use for action names. |
sessionReplay | object | – | Session Replay configuration. |
components | object | – | Component tracking configuration. |
sessionReplay options
| Option | Type | Default | Description |
|---|---|---|---|
svgTracking | boolean | false | Whether to track SVG assets in the context of Session Replay. |
components options
| Option | Type | Default | Description |
|---|---|---|---|
useContent | boolean | true | Whether to use component content (for example: children, props) as the action name. |
useNamePrefix | boolean | true | Whether to prefix actions with the component name. |
tracked | array | – | List of component-specific tracking configs. |
components.tracked[] (per component)
Each entry in the tracked array is an object with the following shape:
| Option | Type | Default | Description |
|---|---|---|---|
name | string | – | The component name to track (e.g., Button). |
useContent | boolean | inherits from global | Override useContent for this component. |
useNamePrefix | boolean | inherits from global | Override useNamePrefix for this component. |
contentProp | string | – | Property name to use for content instead of children (for example: "subTitle"). |
handlers | array | – | List of event/action pairs to track. |
components.tracked[].handlers[]
| Field | Type | Description |
|---|---|---|
event | string | The event name to intercept (such as "onPress"). |
action | string | The RUM action name to associate with this event. (Only "TAP" actions are currently supported) |
Example configuration (using configuration options):
module.exports = {
presets: ['module:@react-native/babel-preset'],
plugins: [
[
'@datadog/mobile-react-native-babel-plugin',
{
actionNameAttribute: 'custom-prop-value',
sessionReplay: {
svgTracking: true
},
components: {
useContent: true,
useNamePrefix: true,
tracked: [
{
name: 'CustomButton',
contentProp: 'text'
handlers: [{event: 'onPress', action: 'TAP'}],
},
{
name: 'CustomTextInput',
handlers: [{event: 'onFocus', action: 'TAP'}],
},
{
useNamePrefix: false,
useContent: false,
name: 'Tab',
handlers: [{event: 'onChange', action: 'TAP'}],
},
],
},
},
],
],
};
Troubleshooting
Note: If you're on an older React Native version, and using Typescript in your project, you may need to install the preset @babel/preset-typescript.
To install with NPM, run:
npm install @babel/preset-typescript
To install with Yarn, run:
yarn add @babel/preset-typescript
Then update your Babel configuration file like using the following example:
module.exports = {
presets: [
'module:@react-native/babel-preset',
'@babel/preset-typescript' // <-- Add here
],
plugins: ['@datadog/mobile-react-native-babel-plugin']
};
