Vinxi server build fails: Big integer literals not available in target environment ("es2019")

I am getting an error when building locally as well as when Netlify tries to build:

.../.vinxi/build/ssr/index.js:1:40327: ERROR: Big integer literals are not available in the configured target environment ("es2019")

I have looked through the Solid Start, Vinxi and Nitro docs to try to figure out where I can configure this to use a more modern target environment. My app.config.ts currently looks like this:

export default defineConfig({
  ssr: true,
  server: {
    prerender: {
      routes: ["/", "/about", "/manage"],
    },
  },
  vite: {
    optimizeDeps: {
      include: [
        "@perawallet/connect",
        "@blockshake/defly-connect",
        "@walletconnect/modal",
        "@walletconnect/sign-client",
        "algosdk",
      ],
      esbuildOptions: {
        target: "es2020",
        // Node.js global to browser globalThis
        define: {
          global: "globalThis",
        },
        supported: {
          bigint: true,
        },
      },
    },
    build: {
      target: ["es2020"],
      commonjsOptions: {
        transformMixedEsModules: true,
      },
    },
    esbuild: { drop: ["console"] },
  },
})

export default defineConfig({
  ssr: true,
  server: {
    prerender: {
      routes: ["/", "/about", "/manage"],
    },
  },
  vite: {
    optimizeDeps: {
      include: [
        "@perawallet/connect",
        "@blockshake/defly-connect",
        "@walletconnect/modal",
        "@walletconnect/sign-client",
        "algosdk",
      ],
      esbuildOptions: {
        target: "es2020",
        // Node.js global to browser globalThis
        define: {
          global: "globalThis",
        },
        supported: {
          bigint: true,
        },
      },
    },
    build: {
      target: ["es2020"],
      commonjsOptions: {
        transformMixedEsModules: true,
      },
    },
    esbuild: { drop: ["console"] },
  },
})

And tsconfig.json:

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ES2020",
    "lib": ["es2020", "esnext"],
    "moduleResolution": "bundler",
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "jsx": "preserve",
    "jsxImportSource": "solid-js",
    "allowJs": true,
    "noEmit": true,
    "strict": true,
    "types": ["vinxi/types/client"],
    "isolatedModules": true,
    "paths": {
      "~/*": ["./src/*"]
    }
  }
}

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "ES2020",
    "lib": ["es2020", "esnext"],
    "moduleResolution": "bundler",
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "jsx": "preserve",
    "jsxImportSource": "solid-js",
    "allowJs": true,
    "noEmit": true,
    "strict": true,
    "types": ["vinxi/types/client"],
    "isolatedModules": true,
    "paths": {
      "~/*": ["./src/*"]
    }
  }
}

Nothing in either config file seems to have any impact on this "configured target environment" so any help on how I can reconfigure this would be much appreciated!

Looks like it belongs to the "server" configuration option, here's a minimal setup to make BigInt work:

export default defineConfig({
    server: {
        esbuild: {
            options: {
                target: 'es2022'
            }
        },
    }
})

export default defineConfig({
    server: {
        esbuild: {
            options: {
                target: 'es2022'
            }
        },
    }
})

I agree that app configuration is difficult and not very thoroughly documented. This required lots of digging into vinxi and nitropack internals, searching for "es2019" inside node_modules/nitropack finally found it.

Hey! I never saw this until now! Should'a tagged me! Thank you SO much for this! It immediately solved my problem. I had the config elsewhere instead of under server:, and so it was not having any effect on the server build 🤦‍♂️. I was pulling my hair out trying to troubleshoot this... 😅 Where does this need to be documented? In the Vinxi config docs?/

Hey I was having the same issue and this solved it for me too! Thanks for posting the question and thanks to kissa for the solution!
