Mali toJSON middleware. If the response object has a toJSON function it's executed upon
payload. Only applies for UNARY and REQUEST_STREAM call types.
Example
const toJSON = require('@malijs/tojson')
function handler(ctx) {
const obj = {
email: 'bob@gmail.com',
password: 'mysecret'
}
obj.toJSON = function() {
return {
email: this.email
}
}
ctx.res = obj // password will not be in the payload to client
}
app.use('fn', toJSON(), handler)
