fetch to curl Playground

38 |

39 | Usually this library should be used together with a package manager like 40 | yarn or 41 | npm. (please 42 | refer to the 43 | README 46 | for general usage information) 47 |

48 |

49 | Note the creation of the exports object in line 11 of this html file, 50 | which mitigates the missing module support of the browser. 51 |

52 |

How to use this playground

53 |
  • Check your browser console (usually opens with F12)
    • 54 |
  • 55 | Try 56 | fetchToCurl("https://example.com", { headers: { "x-test": "test" 58 | }}) 60 | or 61 | console.log(fetchToCurl("https://example.com", { headers: { "x-test": 63 | "test" }})) 65 | in your browser console 66 |
    • 67 |
  • 68 | Note that the you can compare with the real request in the network tab. 69 |
