Searching Bun's documentation (currently the long README on GitHub) for "macro", I only see a brief usage example as part of the build configuration, like: [macros] # Remap any import like this: # import {graphql} from 'react-relay'; # To: # import {graphql} from 'macro:bun-macro-relay'; react-relay = { "graphql" = "bun-macro-relay" } ..Or as a transpiler option: const transpiler = new Bun.Transpiler({ loader: "tsx", define: { "process.env.NODE_ENV": JSON.stringify("development"), user_undefined: "undefined", }, platform: "bun", macro: { inline: { whatDidIPass: `${import.meta.dir}/inline.macro.js`, }, react: { bacon: `${import.meta.dir}/macro-check.js`, }, }, }); ..But not within the transpiled code itself. Ooh, hold on - there's more in /test/macro. Here's hello-fetch-macro.tsx. import { fetchSync } from "macro:./fetchSync.tsx"; const synchronousFetch = fetchSync(`https://example.com`); console.log(synchronousFetch); Looks like the special import syntax converts the function to run at build time. https://github.com/oven-sh/bun/blob/c3bf97002d6f0b117060dabf2aa281eedd85b7fd/test/macro/hello-fetch-macro.tsx https://github.com/oven-sh/bun/blob/c3bf97002d6f0b117060dabf...
