Mongoose and Express built RESTful API


As you build a REST API with mera, you get APIs:

  • GET /?querya=xx&queryb=xx&start_time=xx&end_time=xx&_filter=xx&_page=x&_perPage=x
    • Fully supported List
      • Any allowed field can be added as a query field for filtering
      • JSON string can passed in by _filter, if you prefer
      • Use start_time and end_time to filter a time range if timeFilter is set
      • Use _page and _perPage for pagination, X-Total-Count in response head for total count
      • Use _sortDir (ASC|DESC) and _sortField to sort any allowed field
      • Use format= to export a certain format, now supports
        • csv
        • xlsx
        • json (default)
  • GET /:id
    • Get by ID, simply enough
  • POST /
    • Use JSON body to create a new doc; any unknown field or not allowed field will be omitted
  • PUT /:id
    • Use JSON body to update a doc, similar
  • DELETE /:id
    • Delete by ID


// Create a mongoose model as usual 
var mongoose = require('mongoose'), Schema = mongoose.Schema;
var personSchema = new Schema({
  firstName: String,
  lastName: String
var Person = mongoose.model('Person', personSchema);
// Create the router with the model 
var mera = require('mera');
var router = mera(Person, {
  props: // the properties to be filter at listing, creating or updating 
  propsMapping: // [api prop]: [model prop], if any to be mapped, id: '_id' is always added 
  baseFilter: // used at listing 
  defaultSort: // used at listing 
  protects: // { LIST: function(req, cb), GET: , PUT: , ... } // to protect a certain method 
  _id: // String, used as { options._id: } when /:id is passed in 
  omitProps: // [String], list of all props to omit at output, 'output' is always omitted 
  uploadProps: // {'upload_file_prop': 'prop_to_be_replaced', } 
  timeFilter: // 'field_name', to use this field for time search 
  textFields: [String] // field to be search as text, which means using $regex operator 
app.use('/persons', router); // use in app, all RESTful APIs are available. 

and Frontend?

This API is a perfect companion of ng-admin, an Angular based management UI.

You should be able to satify 99% of your management requirements in 1 hour for a model if your db is ready.
