npm install --save-dev babel-plugin-transform-decorators
Add the following line to your .babelrc file:
{
"plugins": ["transform-decorators"]
}
If you are including your plugins manually and using transform-class-properties
, make sure that transform-decorators
comes before transform-class-properties
.
Currently, transform-class-properties
must be used in loose
mode to support the transform-decorators
. To use transform-class-properties
in spec mode with decorators, wait for the next major version of decorators (Stage 2).
Wrong:
{
"plugins": [
"transform-class-properties",
"transform-decorators"
]
}
Right:
{
"plugins": [
"transform-decorators",
["transform-class-properties", { "loose" : true }]
]
}
babel --plugins transform-decorators script.js
require("babel-core").transform("code", {
plugins: ["transform-decorators"]
});
