Error Handling

• simple error control

api.lastBlock().catch(function(e){
    console.log(e.message)
})

• technical error control

var errors = require('insight-cli/errors')
api.lastBlock()
    .catch(errors.HttpApiError, function (reason) {
        // API ERROR
        console.log(reason.message, "API", reason.error_code)
    })
    .catch(errors.StatusCodeError, function (reason) {
        // HTTP STATUS ERROR(404 or 500, 502, etc...)
        console.log("HTTP StatusCodeError " + reason.statusCode, "HTTP", reason.statusCode)
    })
    .catch(errors.RequestError, function (reason) {
        // REQUEST ERROR(SYSTEMCALL, TIMEOUT)
        console.log(reason.message, "SYSCALL", reason.error.code)
    })
    .catch(function(e){
        // OTHER ERROR
        console.log(e.message)
    })
