@babel/preset-stage-0
As of v7.0.0-beta.54, we've decided to remove the official Babel Stage presets. You can find more information at issue #7770, but the TL;DR is that it's causing more harm than convenience in that the preset is always out of date, each change is usually going to require a major version bump and thus people will be behind, and it encouraged too many people to opt-in to too many proposals that they didn't intend to. This is intended to be the last publish of "@babel/preset-stage-0"
If you want the same configuration as before:
{
"plugins": [
// Stage 0
"@babel/plugin-proposal-function-bind",
// Stage 1
"@babel/plugin-proposal-export-default-from",
"@babel/plugin-proposal-logical-assignment-operators",
["@babel/plugin-proposal-optional-chaining", { "loose": false }],
["@babel/plugin-proposal-pipeline-operator", { "proposal": "minimal" }],
["@babel/plugin-proposal-nullish-coalescing-operator", { "loose": false }],
"@babel/plugin-proposal-do-expressions",
// 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: [
// ...
],
};
};
