BaseError

Base class for every SDK error. Carries structured metadata for triage.

Definition

class BaseError extends Error {
  override name: string             // "BaseError"
  shortMessage: string
  details: string
  metaMessages?: string[]
 
  constructor(shortMessage: string, args?: {
    cause?: BaseError | Error
    details?: string
    metaMessages?: string[]
    name?: string
  })
}

Fields

name — string. Discriminator. Overridden by subclasses ("HttpRequestError", "TimeoutError", "UrlRequiredError").

shortMessage — string. The one-line summary passed at construction.

details — string. Detailed explanation. Derived from cause.details (when cause is a BaseError) or cause.message, else from the explicit details arg.

metaMessages — string[] | undefined. Contextual lines composed into the final message.

Narrowing

BaseError is not currently exported from @left-curve/sdk. There is no @left-curve/sdk/errors subpath. Narrow by name instead of instanceof:

try {
  await client.getBalance({ address, denom: "dango" })
} catch (err) {
  if (err instanceof Error && err.name === "HttpRequestError") {
    // handle network failure
  }
}

The final message is composed as:

{shortMessage}
{metaMessages joined by newline}
 
Details: {details}

Notes

  • For richer narrowing today, check err.name against the known discriminator strings ("BaseError", "HttpRequestError", "TimeoutError", "UrlRequiredError").
  • See Concepts: Error Handling for the recommended pattern.
