Installation

Usage
With a configuration file (Recommended)
Without options:
{ "plugins": ["@babel/plugin-transform-template-literals"] }
With options:
{ "plugins": [ [ "@babel/plugin-transform-template-literals", { "loose": true } ] ] }
Via CLI
babel --plugins @babel/plugin-transform-template-literals script.js
Via Node API
require("@babel/core").transformSync("code", { plugins: ["@babel/plugin-transform-template-literals"], });
Options
loose
boolean
, defaults to false
.
⚠️ Consider migrating to the top level
mutableTemplateObject
assumption.
// babel.config.json { "assumptions": { "mutableTemplateObject": true } }
When mutableTemplateObject
is 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.
In
`foo${bar}`;
Out
"foo" + bar;
