Understanding Scope and Spans in Effect TypeScript Library
random question, i think my mental picture of scope with respect to spans is incorrect...should the withLogSpan be in a separate pipe? i see a lot of examples with a separate pipe for span declarations, not entirely sure on the why
export const makeLiveProviderService = Effect.gen(function* () {
const ecn = yield* EcnClient; // custom http client
function getByDomain(domain: string) {
const message = "Some fallback error for client";
return pipe(
safeEncodeURI(`/public/sps/${domain}`),
Effect.tap((url) => Effect.logInfo(`Making GET request`, { url })),
Effect.map(HttpClientRequest.make("GET")),
Effect.flatMap(ecn.client.execute),
Effect.tap(Effect.logInfo("Decoding response", { to: "GetByDomainResponseDTO" })),
Effect.flatMap(HttpClientResponse.schemaBodyJson(GetByDomainResponseDTO)),
Effect.tap(Effect.logInfo("Decoding DTO", { to: "ServiceProvider" })),
Effect.flatMap(Schema.decodeUnknown(ServiceProvider)),
Effect.tap(Effect.logInfo("Request successful.")),
Effect.tapErrorCause((cause) => Effect.logError(Cause.pretty(cause))),
Effect.catchAll(() => UnexpectedError.make({ message })),
Effect.withLogSpan("ServiceProvider.getByDomain"),
Effect.scoped,
);
}
return { getByDomain };
});export const makeLiveProviderService = Effect.gen(function* () {
const ecn = yield* EcnClient; // custom http client
function getByDomain(domain: string) {
const message = "Some fallback error for client";
return pipe(
safeEncodeURI(`/public/sps/${domain}`),
Effect.tap((url) => Effect.logInfo(`Making GET request`, { url })),
Effect.map(HttpClientRequest.make("GET")),
Effect.flatMap(ecn.client.execute),
Effect.tap(Effect.logInfo("Decoding response", { to: "GetByDomainResponseDTO" })),
Effect.flatMap(HttpClientResponse.schemaBodyJson(GetByDomainResponseDTO)),
Effect.tap(Effect.logInfo("Decoding DTO", { to: "ServiceProvider" })),
Effect.flatMap(Schema.decodeUnknown(ServiceProvider)),
Effect.tap(Effect.logInfo("Request successful.")),
Effect.tapErrorCause((cause) => Effect.logError(Cause.pretty(cause))),
Effect.catchAll(() => UnexpectedError.make({ message })),
Effect.withLogSpan("ServiceProvider.getByDomain"),
Effect.scoped,
);
}
return { getByDomain };
});
