};
const product = await Product.stored(data);
Bulk stored, stored many data at once. This bulkStored static method will return boolean true if success false if failed.
const data = [
{
name: 'Macbook pro M1',
price: 20000,
description: 'Macbook pro chipset M1 16inch screen...',
},
{
name: 'Macbook pro M2',
price: 40000,
description: 'Macbook pro chipset M2 14inch screen...',
}
];
const products = await Product.bulkStored(data);
Update data using update method. This method will return true if success or false if failed.
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const newData = {
price: 22000,
};
const updated = await product.update(newData);
Update many, using update static method. This method will return true if success or false if failed.
const oldPrice = 20000;
const newPrice = 22000;
const updated = await Product.update({
data: {
price: newPrice,
},
where: [
{ field: 'price', operator: Operator.lte, value: oldPrice },
],
});
Delete data using destroy method. This method will return true if success or false if failed.
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const deleted = await product.destroy();
Delete many data using destroy static method. This method required where condition, and will return true if success or false if failed.
const deleted = await Product.destroy({
where: [
{ field: 'price', operator: Operator.lt, value: 20000 },
],
});
Get single data using findOne static method. This method required where condition will return object if success of null if failed.
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,

}],
});
Get many data using findAll static method. This method required where condition, and have optional parameter limit, and orderBy.
orderBy required 2 property field and sort, sort can be asc or desc.
const products = await Product.findAll({
where: [{
field: 'price',
operator: Operator.gte,
value: 20000,
}],
limit: 10,
orderBy: {
field: "updated_at",
sort: "desc"
}
});
Get count of collection from the database by calling count(). This method has where condition, and will return number if success of null if failed
const totalProduct = await Product.count(
where: [{
field: 'price',
operator: Operator.gte,
value: 20000,
}],
);
Reload an instance from the database by calling refresh().
await product.refresh();
Using firestore instance directly.
import FirebaseCore from '../core/firebase/FirebaseCore.js';
const snapshot = await FirebaseCore.admin.firestore().collection('myCollection').get();
snapshot.docs.forEach((doc)=>{
.... document
});
Any instance of model has 'info' method with information.
const info = product.info();
// collection -> collection name
// fields -> fields of model
// hasRole -> has role status
// doc -> raw data of document
// id -> document id
// ref -> reference document
// data -> data
// role -> role data
// medias -> array of medias

All model by default has created_at and updated_at property as timestamp.
to convert to datetime using toDate().
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const productData = {
id: product.id,
name: product.name,
price: product.price,
created_at: product.created_at.toDate(),
updated_at: product.updated_at.toDate(),
}
Any model already has ability to save and get media.
Save file using saveMedia method. The method required file object and media name, and will return media object if success or null if failed.
If the instance already has a file with the same name, then the file will be replaced with a new file.
const id = req.params.id;
const { image } = req.body;
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const media = await product.saveMedia(image, 'thumbnail');
Get all media by calling instance.getMedia().
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
product.getMedia() // return list of object
Get media by name, params is media name, will return media object if success and null if failed.
product.getMedia('thumbnail') // return single object
product.getMedia('thumbnail').url // return single object url
Destroy media by calling instance.destroyMedia(mediaName). This method will return true if success and false if failed.
const product = await Product.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const deleted = await product.destroyMedia('thumbnail')
Using saveMedia directly and return url and path.
const { avatar } = req.body;
const myAvatar = await FirebaseCore.saveMedia(avatar);
const { url, path } = myAvatar;
Using deleteMedia or deleteMedias to delete media.
await FirebaseCore.deleteMedia(mediaPath); // delete single media.
await FirebaseCore.deleteMedias(mediaPaths); // delete many media at once.
All media files will be automatically deleted whenever instance of model is deleted.
Handling Content-Type header for
- application/json
- application/form-data
- application/x-www-form-urlencoded

Create Custom Rule via cli.
npx fireme make:rule GmailRule
The Rule will be created in the rules directory.
class GmailRule {
constructor() {
}
/**
* Determine if the validation rule passes.
* @param {*} attribute
* @param {*} value
* @returns bolean
*/
passes(attribute, value) {
return value.includes("@gmail.com")
}
/**
* Get the validation error message.
*
* @return string
*/
message() {
return 'The _attribute_ must be using @gmail.com'
}
}
export default GmailRule
rules() {
return {
"email": {
"rules": [ new GmailRule, "required","email" ]
}
}
}
Default error messages outputs are dependent on the locale. If you haven't set up the locale as a middleware, it will be set to English en by default.
A user model can have a role by set hasRole to true.
User.init({
fields: {
name: {
type: DataTypes.string,
},
email: {
type: DataTypes.string,
},
password: {
type: DataTypes.string,
},
},
collection: 'users',
hasRole: true, // set true
});
If the user instance already has a role, then the user role will be replaced with a new role. instance.setRole(params) params is role name. setRole will return status in boolean.
const user = await User.stored({
name: 'andre',
emmail: '[email protected]',
password: 'mypassword',
});
const status = await user.setRole('admin');
Get role object by calling instance.getRole(), or direcly access role name instance.getRole().name.
const role = user.getRole() // role object
const roleName = user.getRole().name // role name
Get permission by calling instance.getRole().permissions will get array of permissions name.
const permissions = user.getRole().permissions; // array of permissions name [ "user-create","user-stored"]
- Remove role from an instance.
const removed = await user.removeRole();
Limitation user access using gateAccess(userInstance,permissionNames), permissionNames must be an array of permission names.
import gateAccess from '../core/service/RolePermission/RolePermissionService.js';
if (!gateAccess(user, ["user-create","user-stored","user-access"]))
return res.sendStatus(403); // return forbidden status code
import Permission from '../core/service/RolePermission/Permission.js';
const permissions = [
"user-create",
"user-stored",
"user-edit",
"user-update",
"user-delete",
"user-search"
]
for (let permission of permissions) {
await Permission.stored({ name: permission })
}
import Role from '../core/service/RolePermission/Role.js';
const roles = [ "admin","customer" ]
for (let role of roles) {
await Role.stored({ name: role })
}
Assign permissions to a role by update. Permissions must be an array of permission names.
const permissions = [
"user-create",
"user-stored"
]
const roleAdmin = await Role.findOne({
where: [{
field: 'name',
operator: Operator.equal,
value: 'admin',
}],
});
if (roleAdmin) {
await roleAdmin.update({permissions: permissions})
}
There is no ref between permission and role, permission only stored all permission. The role has own field type an array to stored permission.
Create new resource via cli.
npx fireme make:resource UserResource
The Resource will be created in resources/UserResource.js directory.
import Resource from "../core/resource/Resource.js"
class UserResource extends Resource {
constructor() {
super().load(this)
}
/**
* Transform the resource into custom object.
*
* @return
*/
toArray(data) {
return {}
}
}
export default UserResource
To create resources from a single object use make or collection for an array of objects.
let userResource = new UserResource().make(user); // for single object
let userResources = new UserResource().collection(users); // for array of object
class UserResource extends Resource {
constructor() {
super().load(this)
}
toArray(data) {
return {
"id": data.id,
"name": data.name,
"email": data.email,
"image": data.getMedia("avatar")?.url || '',
"role": data.getRole()?.name || '',
}
}
}
const id = req.params.id;
const user = await User.findOne({
where: [{
field: 'id',
operator: Operator.equal,
value: id,
}],
});
const userResource = new UserResource().make(user);
return res.json(userResource);
{
"id": 'b96jRXfy8nSfZqk545SN',
"name": 'Andre',
"email": '[email protected]',
"image": 'https://storage.googleapis.com/projectx.appspot.com/91ecb634-46dd-4fce-995c-b38d4eaa2bd1.jpeg',
"role": 'admin',
}
Create token by calling JwtAuth.createToken(), that will return refreshToken and accessToken.
const payload = {
id: user.id,
name: user.name,
email: user.email
}
const token = JwtAuth.createToken(payload)
console.log(token.refreshToken)
console.log(token.accessToken)
Regenerate access token by calling JwtAuth.regenerateAccessToken(refreshToken), that will return new access token.
const accessToken = JwtAuth.regenerateAccessToken(refreshToken)
Get authenticated user by calling JwtAuth.getUser(email), that will get user by email.
const user = await JwtAuth.getUser(email)
Or you just setup the .env AUTH_GET_CURRENT_USER_ON_REQUEST=true and you can access current authenticated user by access
req.user. You can found the code where current user instance set to req.user in core/middleware/JwtAuthPass.js file.
req.user = await JwtAuth.getUser(email);
Before using JwtAuth.GetUser(), ensure that you have set up your User model inside the AuthConfig in the core/config/Auth.js file.
- Default user model for auth in
core/config/Auth.js.
class AuthConfig {
/**
* Default user model for auth
* @returns
*/
static user = User
It is crucial that your User model has a email field, as JwtAuth.GetUser() will retrieve the user instance based on the email by default. However, if you prefer to retrieve the current authenticated user in a different manner, you can modify the JwtAuth.GetUser() function to suit your needs in core/auth/JwtAuth.js file.
For secure access to controller by adding JwtAuthPass to your router.
import JwtAuthPass from '../core/middleware/JwtAuthPass.js';
routerAuth.use(JwtAuthPass)
routerAuth.get("/upload", UserController.upload)
app.use("/api",routerAuth)
For secure access to controller by adding BasicAuthPass to your router.
import BasicAuthPass from '../core/middleware/BasicAuthPass.js';
routerAuth.use(BasicAuthPass)
routerAuth.get("/upload", UserController.upload)
app.use("/api",routerAuth)
Before using this, make sure already set username and password for basic auth in .env file.
AUTH_BASIC_AUTH_USERNAME=myBasicUsername
AUTH_BASIC_AUTH_PASSWORD=myBasicPassword
Setup locale in core/config/Locale.js. by default locale setup to english en
defaultLocale: "en",
useLocale: useLocale,
locales: ["en", "id"]
You can add more locale Code to locales. By default locales are only available for English en, and for Indonesia id.
After adding additional locales, it is important to update the validation error messages in the core/locale/LangValidation.js file, as the messages generated will depend on the selected locale.
const langValidation = Object.freeze({
required: {
en: "The _attribute_ is required",
id: "_attribute_ wajib di isi",
//ja: "_attribute_ ........." -> adding new validation messages for code ja
},
email: {
en: "The _attribute_ must in E-mail format",
id: "_attribute_ harus dalam format E-mail",
},
match: {
en: "The _attribute_ must be match with _param1_",
id: "_attribute_ harus sama dengan _param1_"
},
......
Its easy to use locale, just setup .env LOCALE_USE=true, then this will effect to all routes, so that have to has a params for locale, for the API router it should be /api/:locale and for the web router it should be /:locale.
// example for api route
const routerAuth = express.Router()
routerAuth.use(JwtAuthPass)
routerAuth.get("/user", UserController.getUser)
routerAuth.post("/upload", UserController.upload)s
app.use("/api/:locale", routerAuth)
// http://localhost:5000/api/en/endpoint | http://localhost:5000/api/id/endpoint
If you don't want to set the locale for all routes, only for a particular route, then simply set up the .env as LOCALE_USE=false. Then you can use the LocalePass middleware directly to your route.
import LocalePass from '../core/middleware/LocalePass.js';
// example for web route
app.get("/:locale",LocalePass, (req, res) => {
// http://localhost:5000/en | http://localhost:5000/id
// example for api route
app.get("/api/:locale/login",LocalePass, (req, res) => {
// http://localhost:5000/api/en/login | http://localhost:5000/api/id/login
All routers that using LocalePass will have the locale Code on req, accessible via req.locale.
Create mail via cli.
npx fireme make:mail AccountVerify
The mail will be created in the mails directory, with examplefile.txt and template.ejs
import Mail from "../../core/mail/Mail.js"
class AccountVerify extends Mail {
constructor(from = String, to = [], subject = String) {
super().load({
from: from,
to: to,
subject: subject,
text: "Just need to verify that this is your email address.",
attachments: [
{
filename: "theFile.txt",
path: "mails/AccountVerify/examplefile.txt"
},
],
html: {
path: "mails/AccountVerify/template.ejs",
data: {
title: "Welcome to the party!",
message: "Just need to verify that this is your email address."
}
},
})
}
}
export default AccountVerify
The template.ejs using express view engine ejs to render html into mail content.
<!DOCTYPE html>

To use this template.ejs, you need to add an html object with a path and data (if needed) into super().load() method.
html: {
path: "mails/AccountVerify/template.ejs", // path is required
data: // data is optional base on your template.ejs
{
title: "Welcome to the party!",
message: "Just need to verify that this is your email address."
}
}
To send email by calling instance.send()
const sendMail = new AccountVerify("[email protected]",["[email protected]"],"Verify Account")
await sendMail.send()
To send files, you need to add an attachments to super().load(). See full doc.
attachments: [
{
filename: "theFile.txt",
path: "mails/AccountVerify/examplefile.txt"
}
]
