# @babel/plugin-transform-template-literals
|
|
|
|
> Compile ES2015 template literals to ES5
|
|
|
|
## Example
|
|
|
|
**In**
|
|
|
|
```javascript
|
|
`foo${bar}`;
|
|
```
|
|
|
|
**Out**
|
|
|
|
```javascript
|
|
"foo".concat(bar);
|
|
```
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install --save-dev @babel/plugin-transform-template-literals
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Via `.babelrc` (Recommended)
|
|
|
|
**.babelrc**
|
|
|
|
Without options:
|
|
|
|
```json
|
|
{
|
|
"plugins": ["@babel/transform-template-literals"]
|
|
}
|
|
```
|
|
|
|
With options:
|
|
|
|
```json
|
|
{
|
|
"plugins": [
|
|
["@babel/transform-template-literals", {
|
|
"loose": true
|
|
}]
|
|
]
|
|
}
|
|
```
|
|
|
|
### Via CLI
|
|
|
|
```sh
|
|
babel --plugins @babel/transform-template-literals script.js
|
|
```
|
|
|
|
### Via Node API
|
|
|
|
```javascript
|
|
require("@babel/core").transform("code", {
|
|
plugins: ["@babel/transform-template-literals"]
|
|
});
|
|
```
|
|
|
|
## Options
|
|
|
|
### `loose`
|
|
|
|
`boolean`, defaults to `false`.
|
|
|
|
When `true`, tagged template literal objects aren't frozen. All template literal expressions and quasis are combined with the `+` operator instead of with `String.prototype.concat`.
|
|
|
|
When `false` or not set, all template literal expressions and quasis are combined with `String.prototype.concat`. It will handle cases with `Symbol.toPrimitive` correctly and throw correctly if template literal expression is a `Symbol()`. See [babel/babel#5791](https://github.com/babel/babel/pull/5791).

**In**
