npm install --save-dev babel-template
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
import template from "babel-template";
|
|
import generate from "babel-generator";
|
|
import * as t from "babel-types";
|
|
|
|
const buildRequire = template(`
|
|
var IMPORT_NAME = require(SOURCE);
|
|
`);
|
|
|
|
const ast = buildRequire({
|
|
IMPORT_NAME: t.identifier("myModule"),
|
|
SOURCE: t.stringLiteral("my-module")
|
|
});
|
|
|
|
console.log(generate(ast).code);
|
|
```
|
|
|
|
```js
|
|
const myModule = require("my-module");

## API
|
|
|
|
### `template(code, [opts])`
|
|
|
|
#### code
|
|
|
|
Type: `string`
|
|
|
|
#### options
|
|
|
|
`babel-template` accepts all of the options from [babylon], and specifies
|
|
some defaults of its own:
|
|
|
|
* `allowReturnOutsideFunction` is set to `true` by default.
|
|
* `allowSuperOutsideMethod` is set to `true` by default.
|
|
|
|
##### preserveComments
|
|
|
|
Type: `boolean`
|
|
Default: `false`
|
|
|
|
Set this to `true` to preserve any comments from the `code` parameter.
|
|
|
|
#### Return value
|
|
|
|
`babel-template` returns a `function` which is invoked with an optional object
|
|
of replacements. See the usage section for an example.
