# Migrate from Angular's i18n

## Command

{% tabs %}
{% tab title="Angular CLI" %}

```bash
pnpm add @jsverse/transloco-schematics
ng g @jsverse/transloco-schematics:ng-migrate
```

{% endtab %}

{% tab title="Nx 🐋" %}

```bash
pnpm add @jsverse/transloco-schematics
nx g @jsverse/transloco-schematics:ng-migrate
```

{% endtab %}
{% endtabs %}

***

### The Translation File

The migration script will extract all translations from your HTML files and generate a translations JSON file. The script will use the translation string as the key, converting it to kebab case (e.g., "`My sample string`" → "`my-sample-string`"). Here's an example of the output JSON:

{% code title="en.json" %}

```json
{
  "my-sample-string": "My sample string",
  "my-title": "My title"
}
```

{% endcode %}

#### **Example HTML section and matching JSON output**

{% code title="before.html" %}

```html
<h1 i18n>translation value</h1>
<h1 i18n="site header|value 1 sample">Val1</h1>
<h1 i18n="site header|value 2 sample">Val2</h1>
<h1 i18n="other context|another comment@@myId">Val3</h1>
```

{% endcode %}

{% code title="after.json" %}

```json
{
  "translation-value": "translation value",
  "site header": {
    "val1": "Val1",
    "val1.comment": "value 1 sample",
    "val2": "Val2",
    "val2.comment": "value 2 sample"
  },
  "other context": {
    "myId": "Val3",
    "myId.comment": "another comment"
  }
}
```

{% endcode %}

{% hint style="info" %}
*The `.comment` suffix is used to support comments in Transloco.Note:*
{% endhint %}

***

### Directives

The `i18n` and `i18n-<attribute>` directives will be replaced with the `transloco` pipe.

{% code title="before.html" %}

```html
<h1 i18n>Hello World</h1>
<h1 i18n="other context|another comment@@myId">Some value</h1>
<img src="..." i18n i18n-title="Wow image" />
```

{% endcode %}

{% code title="after.html" %}

```html
<h1>{{ 'hello-world' | transloco }}</h1>
<h1>{{ 'some-value' | transloco }}</h1>
<img src="..." title="{{ 'wow-image' | transloco }}" />
```

{% endcode %}

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://jsverse.gitbook.io/transloco/migration-guides/migrate-from-angulars-i18n.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
