How do you unify TypeScript for both frontend and backend?

#webdev #typescript #discuss #swagger

As far as I know, there are only handful of frameworks doing this, e.g. blitz.js and frourio.

However, I know another easy way - Swagger/OpenAPI + typegen + Nodemon.

// nodemon.json { "restartable": "rs", "execMap": { "ts": "yarn ts" }, "events": { "restart": "yarn openapi || :" }, "watch": [ "server/" ], "env": { "NODE_ENV": "development" }, "ext": "ts" }
Enter fullscreen mode Exit fullscreen mode 
// package.json { "scripts": { "openapi": "wait-on tcp:$SERVER_PORT && curl -s http://localhost:$SERVER_PORT/api/doc/json -o ./assets/openapi.json && typegen ./assets/openapi.json > ./types/openapi.d.ts", "ts": "ts-node -r tsconfig-paths/register -O '{\"module\":\"commonjs\",\"noImplicitAny\":false}'" } }
Enter fullscreen mode Exit fullscreen mode

And typegen is openapi-client-axios-typegen. (You can also try swaxios, but I failed to run it.)

With this approach, backend can be any programming languages that support OpenAPI or Swagger. Personally, I use fastify-swagger; but it can also be things like Python's FastAPI or Golang's Gin/Buffalo/Native.
