Description
I know this is more of nuxt(v2) problem and I have opened an issue to them but I am looking for the possible reason I can find.
This is my babel.conig.js
. It works for all my other webpack projects except for nuxt (app). For nuxt app, from the output message I think it will only transpile but not polyfill and IE 11 does fail to show the page
presets: [
[
// '@babel/preset-env',
'@nuxt/babel-preset-app',
{
debug: true,
targets: {
chrome: '100',
ie: '10',
firefox: '100'
},
useBuiltIns: 'usage',
shippedProposals: true,
modules: "commonjs",
corejs: '3.25'
}
]
]
For my other webpack project, the only different is I use '@babel/preset-env' instead of '@nuxt/babel-preset-app' (but I tried both of them). From the webpack output I can see it will transpile and polyfill my app,
// The transpile part
Using targets:
{
"chrome": "100",
"firefox": "100",
"ie": "10",
}
Using modules transform: commonjs
Using plugins:
proposal-numeric-separator { ie }
proposal-logical-assignment-operators { ie }
...
// The polyfill part
The corejs3 polyfill added the following polyfills:
es.array.concat { "ie":"10" }
es.object.to-string { "ie":"10" }
es.regexp.to-string { "ie":"10" }
...
But for my nuxt app, I only see the transpile part but no polyfill part and IE 11 can't open the page
@babel/preset-env: DEBUG option
Using targets:
{
"chrome": "100",
"firefox": "100",
"ie": "10"
}
Using modules transform: commonjs
Using plugins:
transform-unicode-sets-regex { chrome < 112, firefox < 116, ie }
bugfix/transform-v8-static-class-fields-redefine-readonly { ie }
proposal-class-static-block { ie }
syntax-private-property-in-object
syntax-class-properties
proposal-numeric-separator { ie }
...
corejs3: DEBUG option
Using targets: {
"chrome": "100",
"firefox": "100",
"ie": "10"
}
Using polyfills with usage-global method:
regenerator: DEBUG option
Using targets: {}
From the output I only see plugins to transpile and the fact IE 11 fails to open the page make me I draw the conclusion no polyfill for my nuxt app. But I am not 100% sure this is the case. I asked the question at babel/babel#16253 but since I am desperate to find the reason I am also opening an issue here.
