Handler Signature

Handler files should export a function that returns a hapi handler function:

`javascript
// handlers/userHandler.js
'use strict';

module.exports = (route, options) => {
// route: the hapi route configuration
// options: options passed from route handler config

return (request, h) => {
return {
message: options.message || 'Default message',
user: request.params.id
};
};
};
`

$3

`javascript
server.route({
method: 'GET',
path: '/user/{id}',
handler: {
userHandler: {
message: 'User details'
}
}
});
`

$3

`javascript
module.exports = (route, options) => {
return async (request, h) => {
const user = await fetchUser(request.params.id);
return user;
};
};
`

Migration from v2/v3

Version 4.0.0 has breaking changes to support hapi v21+:

$3

`javascript
// v2/v3 (hapi v13-v16)
server.register({
register: require('hapi-handlers'),
options: { ... }
}, callback);

// v4 (hapi v21+)
await server.register({
plugin: require('hapi-handlers'),
options: { ... }
});
`

$3

`javascript
// v2/v3
module.exports = (route, options) => {
return (request, reply) => {
return reply({ message: 'Hello' });
};
};

// v4
module.exports = (route, options) => {
return (request, h) => {
return { message: 'Hello' };
// or: return h.response({ message: 'Hello' });
};
};
`

$3

`javascript
// v2/v3
const server = new Hapi.Server();
server.connection({ port: 3000 });

// v4
const server = Hapi.server({ port: 3000 });
