Contract-first frontend delivery with OpenAPI and MSW
A pragmatic pattern for keeping frontend teams productive while backend contracts are still moving.
Contract-first delivery gives frontend work a stable surface before every backend detail is finished. Generated OpenAPI clients reduce hand-written integration code, while MSW mock services let teams exercise workflows with realistic API behavior.
The maintenance win is clarity: request and response shapes are explicit, mock behavior lives close to the feature, and integration changes are easier to review.
