{
"presets": [
["env", {
"modules": false,
"targets": {
"browsers": ["> 1%", "last 2 versions", "not ie <= 8"]
}
}],
"stage-2",
["es2015"]
],
"plugins": [
"transform-vue-jsx",
"transform-runtime",
["syntax-dynamic-import"],
["component", [
{
"libraryName": "element-ui",
"styleLibraryName": "~theme"
}
]]
],
"env": {
"test": {
"presets": ["env", "stage-2"],
"plugins": ["transform-vue-jsx", "transform-es2015-modules-commonjs", "dynamic-import-node"]
}
}
}
