sequelize-serialize
The way to serialize Sequelize models using JSON Schema. Supports complex resources and associated models.
Example
Let’s say we need to return all users with posts in the blog, including the comments to these posts:
router.get('/blog/users', async (ctx) => {
const users = await User.findAll({
include: [{
model: Post,
required: true,
include: [Comment]
}]
});
ctx.body = serialize(users, schemas.UserWithPosts);
});
We can describe JSON fields for that with following schemas:

"UserWithPosts": {

"properties": {
"name": {
"type": "string"
},
"isAdmin": {

},
"posts": {

{ type: 'null' }
