Examples

Generate C# to parse a Bitcoin API

  $ quicktype -o LatestBlock.cs https://blockchain.info/latestblock             

Generate Go code from a directory of samples containing:

  - Foo.json                                                                    
  + Bar                                                                         
  - bar-sample-1.json                                                           
  - bar-sample-2.json                                                           
  - Baz.url 

  $ quicktype -l go samples                                                     

Generate JSON Schema, then TypeScript

  $ quicktype -o schema.json https://blockchain.info/latestblock                
  $ quicktype -o bitcoin.ts --src-lang schema schema.json
