examples/curl_template/README.md

Download & return URL via curl

An example repo to kick-off building services on Fluence.

What it does:

• exploits mounted_binaries to call /usr/bin/curl on the host OS
• downloads any url, and returns its content as a resulting String

BackendConfig.json

Wasm module is configured with this simple JSON config:

{
  // import name of the module; needed when linking modules in multi-module setups
  "name": "curl_adapter",
  // binaries available to call
  "mountedBinaries":
    {
      // curl will be callable as a host function
      "curl": "/usr/bin/curl"
    }
}

P.S. JSON5 has comments! yaaay!
