webmongo

About us

Accessing server-side mongodb through client javascript API. This project is a branch of dbcloud

You can do almost invoke on mongodb through the javascript API in browser.

The client javascript api support IE6.0+ Chrome FireFox and Wechat

web: http://mongo.dbcloud.org

mail: webmongo@csmake.com

Application scenarios

  • Rapid prototyping does not need to write server-side code.

  • Academic teaching and research, WYSIWYG

  • Enterprise internal application

  • Other applications that do not focus on the security of the database table structure.

Start the basic project

  1. Run mongod first.
  2. Put webmongo.war in your servlet server webapps ,Apache Tomcat8.0 , Glass Fish Server4.x and so on.
  3. Open browser(Chrome FireFox IE) and put http://localhost:8080/webmongo/, The address may be different depending on your settings

Start to write your web application

  1. Copy MongoCollection.java and MongoCollectionServlet.java from webmongo.war /src/java/.. , into your src/java/org/dbcloud/mongodb

  2. Copy all *.js files in webmongo.war /js to your js directory. JQuery is necessary. IE6.0 need to use the 1.x version and json2.js is necessary.

  3. Edit the web.xml, like this:


    <servlet>
        <servlet-name>MongoCollectionServlet</servlet-name>
        <servlet-class>org.dbcloud.mongodb.MongoCollectionServlet</servlet-class>
        <init-param>
            <param-name>dbhost</param-name>
            <param-value>127.0.0.1</param-value>
        </init-param>
        <init-param>
            <param-name>dbport</param-name>
            <param-value>27017</param-value>
        </init-param> 
        <init-param>
            <param-name>db</param-name>
            <param-value>test</param-value>
        </init-param>
        <init-param>
            <param-name>connection</param-name>
            <param-value>test</param-value>
        </init-param>
        <init-param>
            <param-name>user</param-name>
            <param-value></param-value>
        </init-param>
        <init-param>
            <param-name>password</param-name>
            <param-value></param-value>
        </init-param> 
    </servlet>
    <servlet-mapping>
        <servlet-name>MongoCollectionServlet</servlet-name>
        <url-pattern>/org.dbcloud.mongodb.MongoCollection</url-pattern>
    </servlet-mapping>

                }
                var table = new org.dbcloud.mongodb.MongoCollection();
                log("clear table");
                table.deleteMany({});
                log("insertOne and set options");
                table.insertOne({name: 'validation'}, {validation: true});
                log("count:" + table.count({index: {'$exists': true}}));
                var data = table.find({'index': {'$gt': 5}}, {projection: {'_id': 0}});
                log("find index > 5 and exclude _id column");
                log(JSON.stringify(data));
                log("replaceOne");
                table.replaceOne({name: 'dbcloud'}, {name: 'replace', status: 0});
                log("updateMany with options ");
                table.updateMany({'index': {'$gt': 10}}, {'$set': {name: 'updateMany', status: 100, index: 100}}, {upsert: true, validation: false});
                log("find all");
                var data = table.find();
                log(JSON.stringify(data));
                log('findOneAndUpdate');
                log(JSON.stringify(table.findOneAndUpdate({'index': {'$gt': 10}}, {'$set': {name: 'findOneAndUpdate'}, '$inc': {index: -1}})));
                table.close();
            } catch (e) {
                alert(e.message);
