| My company has been flirting with graphql. As a frontend dev, I had a positive experience with one service because the backend was far more willing to add new query options. The much publicized "only get what you ask for" part was largely irrelevant. I am, however, unsettled at the prospect is losing all the built in network and browser caching for idempotent calls (mostly I'm unsettled because no one else seems to seriously consider the issue - it may end up too small to matter, but I dont trust that anyone else here has honestly evaluated it). Another poster mentioned the issue with partial errors, which sounds like something else that will not get the upfront attention it deserves, while not being an immediate dealbreaker. Add in to that how to manage deprecation of particular query statements as they can no longer be distinguished as distinct endpoints. My other concern is how much magic frontend libraries provide. This magic looks great if your app is nothing more than input/output over CRUD calls, but sounds very brittle if your app has client side logic (and while perhaps a webapp should ideally avoid that, other services can also be clients.) So far I have concerns but not concrete problems, I just worry that we wont be able to confirm the severity until we've already invested and committed, particularly when our initial adopters are so enthusiastic. At the same time I don't want to be the guy unwilling to change and adopt new things. |
