    Mongo Rester

    by Alex Merced

    Spin up a Full Crud Mongo Express API with one function

    How it works

    Install it...

    npm install mongorester

    require it...

    const { rester } = require("mongorester");

    Pass the rester function a model name string and schema definition object. The function will return an array with the model and the router with 5 pre-made routes.

    //Generate Model and Router
    const [Note, noteRouter] = rester("Note", { title: String, content: String });
    //add extra routes if you want
    noteRouter.get("/user/:username", async (req, res) => {
      res.json(await Note.find({ username: req.params.username }));
    //Use the Router
    app.use("/note/", noteRouter);

    The Pre-Made Routes

    Here is the Routes that get created when using the rester function

    router.get("/", async (req, res) => {
      try {
        res.status(200).json(await Model.find({}));
      } catch (error) {
        res.status(400).json({ error });
    router.get("/:id", async (req, res) => {
      try {
        res.status(200).json(await Model.findById(;
      } catch (error) {
        res.status(400).json({ error });
    //CREATE"/", async (req, res) => {
      try {
        res.status(200).json(await Model.create(req.body));
      } catch (error) {
        res.status(400).json({ error });
    router.put("/:id", async (req, res) => {
      try {
          .json(await Model.findByIdAndUpdate(, req.body));
      } catch (error) {
        res.status(400).json({ error });
    router.delete("/:id", async (req, res) => {
      try {
        res.status(200).json(await Model.findByIdAndRemove(;
      } catch (error) {
        res.status(400).json({ error });

    The Config Object

    Can pass a third config object argument that'll help add middleware and configure your schema.

    //config object
    const config = {
      middleware: [auth], //array of middleware function, must be an array
      config: { timestamps: false }, //second argument of Schema, default timestamps true
      indexQuery: (req, res) => {
        username: req.query.username;
      //Function that takes req/res and returns object to query for index route
    //Generate Model and Router
    const [Note, noteRouter] = rester(
      { title: String, content: String },

    Overriding Default Routes

    You can pass an alternate route handler into the config object under the following keys:

    • index
    • show
    • update
    • create
    • destroy

    with the following function signature

    (req, res, model) => {}


    Another function inside Mongo Rester is Authy which will quickly implement JWT user authentication. (uses a bearer token)

    const { authy } = require("mongorester");

    Using it is as easy as this...

    userSchema = {
      username: String,
      password: String,
      email: String,
    schemaConfig = {
      timestamps: true,
    options = {
      secret: "cheese",
      tokenConfig: {
        expiresIn: "1h",
    const [User, authMiddleware, authRouter, authRester] = authy(

    User: The user model.

    authMiddleware: Middleware functions to protect routes. It will store the token payload in req.payload

    authRouter: auth router with "/register" and "/login" post routes. THe login route will generate a token that holds all the user object except the password.

    authRester: Like the rester function except it applies the authMiddleware to all routes, already has all CRUD routes like rester.


    Simple Mongo connection simplifier. Just pass it your mongo uri and it will return the connected mongoose object with basic event logs for open, close and error.

    const { connmon, rester, authy } = require("mongorester");
    const mongoose = connmon(uri);


    Pass it a key and data and it will inject that data into the request object under that key. It returns a middleware function.

    const { reqInjector } = require("mongorester");
    const { User, Blog } = require("./models");
    //This makes all models available to all routes inside req.models
    app.use(reqInjector("models", { User, Blog }));


    In a lot of situations you have to pass a callback (think app.listen) which often just contains a console.log, so cbLog is a quick way to pass these messages in a colorful way.

    cbLog(key, message)

    const {cbLog} = require("mongorester")
    app.listen(PORT, cbLog("server", `Listening on ${PORT})`)
