Error: [BABEL] /HOME/react-dashboard-try/tools/run.js:
As of v7.0.0-beta.55, we've removed Babel's Stage presets.
Please consider reading our blog post on this decision at
https://babeljs.io/blog/2018/07/27/removing-babels-stage-presets
for more details. TL;DR is that it's more beneficial in the
long run to explicitly add which proposals to use.
For a more automatic migration, we have updated babel-upgrade,
https://github.com/babel/babel-upgrade to do this for you with
"npx babel-upgrade".If you want the same configuration as before:
{
"plugins": [
// Stage 2
["@babel/plugin-proposal-decorators", { "legacy": true }],
"@babel/plugin-proposal-function-sent",
"@babel/plugin-proposal-export-namespace-from",
"@babel/plugin-proposal-numeric-separator",
"@babel/plugin-proposal-throw-expressions",
// Stage 3
"@babel/plugin-syntax-dynamic-import",
"@babel/plugin-syntax-import-meta",
["@babel/plugin-proposal-class-properties", { "loose": false }],
"@babel/plugin-proposal-json-strings"
]
}
If you're using the same configuration across many separate projects,
keep in mind that you can also create your own custom presets with
whichever plugins and presets you're looking to use.
module.exports = function() {
return {
plugins: [
require("@babel/plugin-syntax-dynamic-import"),
[require("@babel/plugin-proposal-decorators"), { "legacy": true }],
[require("@babel/plugin-proposal-class-properties"), { "loose": false }],
],
presets: [
// ...
],
};
};
