Server Side Calls

You can directly access the resolve function of any handler. Its type will be inferred automatically.

Example

ts
import { handler, httpError } from 'bridge';
import z from 'zod';
 
const users: Record<string, { firstName: string; lastName: string }> = {
  '1': {
    firstName: 'John',
    lastName: 'Doe',
  },
};
 
const getMyIdWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    if (headers.token === 'token') return { id: '1' };
    else return httpError(400, 'Wrong token');
  },
});
 
const getProfileWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    const res = getMyIdWithToken.resolve({ headers });
          
const res: {
    error: {
        name: "Wrong token";
        data?: any;
        status: 400;
    };
} | {
    id: string;
}
    if ('error' in res) return res;
    return users[res.id];
  },
});

ts
import { handler, httpError } from 'bridge';
import z from 'zod';
 
const users: Record<string, { firstName: string; lastName: string }> = {
  '1': {
    firstName: 'John',
    lastName: 'Doe',
  },
};
 
const getMyIdWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    if (headers.token === 'token') return { id: '1' };
    else return httpError(400, 'Wrong token');
  },
});
 
const getProfileWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    const res = getMyIdWithToken.resolve({ headers });
          
const res: {
    error: {
        name: "Wrong token";
        data?: any;
        status: 400;
    };
} | {
    id: string;
}
    if ('error' in res) return res;
    return users[res.id];
  },
});

This example shows two handlers that can be used as endpoints and called separately. getProfileWithToken uses the resolve function of getMyIdWithToken.

caution

The above example doesn't make much sense, it would be more logical to use getMyIdWithToken as a middleware for getProfileWithToken. This would make the code shorter and clearer. Here is the revised code:

ts
import { handler, httpError, apply } from 'bridge';
import z from 'zod';
 
const users: Record<string, { firstName: string; lastName: string }> = {
  '1': {
    firstName: 'John',
    lastName: 'Doe',
  },
};
 
const getMyIdWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    if (headers.token === 'token') return { id: '1' };
    else return httpError(400, 'Wrong token');
  },
});
 
const getProfileWithToken = handler({
  middlewares: apply(getMyIdWithToken),
  resolve: ({ middlewares }) => users[middlewares.id],
});

ts
import { handler, httpError, apply } from 'bridge';
import z from 'zod';
 
const users: Record<string, { firstName: string; lastName: string }> = {
  '1': {
    firstName: 'John',
    lastName: 'Doe',
  },
};
 
const getMyIdWithToken = handler({
  headers: z.object({ token: z.string() }),
  resolve: ({ headers }) => {
    if (headers.token === 'token') return { id: '1' };
    else return httpError(400, 'Wrong token');
  },
});
 
const getProfileWithToken = handler({
  middlewares: apply(getMyIdWithToken),
  resolve: ({ middlewares }) => users[middlewares.id],
});
