Generate an AST from a string template.
In computer science, this is known as an implementation of quasiquotes.
npm install --save-dev babel-template
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);
const myModule = require("my-module");
template(code, [opts])
Type: string
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.Type: boolean
Default: false
Set this to true
to preserve any comments from the code
parameter.
babel-template
returns a function
which is invoked with an optional object
of replacements. See the usage section for an example.
