esbuild-plugin-named-exports
a esbuild plugion to reexport some named exports
This plugion is used for reexport some named exports.when we change cjs to esm,we can use this plugin
Example we want to change from 'cjs' to 'esm' default in esbuild:
//a.js module.exports.x = 1 module.exports.y = 2 //index.js module.exports = require('./a.js')
after bundle in esbuild, output is:
//bundle.js
var require_a = __commonJS((exports, module) => {
module.exports.x = 1;
module.exports.y = 2;
});
var require_test = __commonJS((exports, module) => {
module.exports = require_a();
});
export default require_test();
you will see that in the bundle.js, it only has "default", there is not namedExports, "export x" and "export".
- my plugin
based on cjs-module-lexer, this plugin can detect all namedExports.
use:
const esbuldNamedExportsPlugin = require('esbuild-plugin-named-exports')
...
require('esbuild').build({
entryPoints: ['./test.js'],
bundle: true,
outdir: 'bundle',
format: 'esm',
target: 'es2017',
plugins:[esbuldNamedExportsPlugin]
})
use this plugin, the bundle.js will be:
//bundle.js
var require_a = __commonJS((exports, module) => {
module.exports.x = 1;
module.exports.y = 2;
});
var require_test = __commonJS((exports, module) => {
module.exports = require_a();
});
var import_test = __toModule(require_test());
var export_default = import_test.default;
var export_x = import_test.x;
var export_y = import_test.y;
export {
export_default as default,
export_x as x,
export_y as y
};
you will see that is has the reexport namedExports, "export x" & "export y"
