esbuild plugin let u use node builtin modules

import { nodeBuiltin } from 'esbuild-node-builtin'

esbuild.build({
  // blabla
  plugins: [nodeBuiltin()],
})

injectGlobal: use esbuild inject for global reference, default true
injectProcess: use esbuild inject for process global reference, default true
injectBuffer: use esbuild inject for Buffer global reference, default false, since this is big AND can not perform tree-shaking
exclude: string[], disable proxy some builtin module

make global.variable = 'value' works in environment has no global, basicly translate to globalThis.variable = 'value'

there are existing packages

AND

rollup-plugin-polyfill-node looks great, resolves to esm modules, and tree-shakable. but is for rollup.

esbuild-plugin-polyfill-node is a esbuild plugin.

~~AND use browserify commonjs deps.~~ AND not tree-shakable
UPDATE: 2023-07, it uses @jspm/core, same not well tree-shakable, e.g path these lines are side effects, and not tree-shakable

e.g

import { format } from 'util'

this package & rollup-plugin-polyfill-node, other exports from util will not be included.
esbuild-plugin-polyfill-node will include entire util.js

this package depends on rollup-plugin-polyfill-node, and use it's internal bundled polyfills. the rollup dep is useless, just prevent error report.
