Documentum REST Services Angular File Manager Sample

The project customizes Angular File Manager to demonstrate the AngularJS application development for Documentum REST Services.

Different with Angular File Manager, we customized the API javascript in the project to make direct access to Documentum REST Services. This is more efficient with respect to the data transfer.

1. Project dependencies

• NodeJS is used to run the app on a server.
• AngularJS is used as the frontend framework.
• Gulp jobs for development, building, emulating, running your app, compiles and concatenates Sass files, local development server with live reload.

Tip

You don't need to setup anything at this moment, please keep patience to follow next sections to install software.

2. Getting started

Preparation

• Assumed that you have Documentum Content Server 7.1+ up and running
• Enable CORS support in Documentum REST Services by customizing dctm-rest.war\WEB-INF\classes\rest-api-runtime.properties, update dfc.properties in the same directory and deploy the WAR.

rest.cors.enabled=true

CORS support is built into Documentum REST Services since 7.3. For previous versions, you need to seek an outside solution, for instance, node-http-proxy. Please read Working-around-CORS for the deployment on REST 7.2 and earlier versions.

Build and Run

• If you don't have NodeJS installed yet, download and install it.

NodeJS 4.x is recommended. You might run into build errors using NodeJS 5.x.

• If you don't have Git installed yet, download and install it.
• If you don't have bower installed yet, run below CLI command to install it:

> npm install -g bower

• If you don't have gulp installed yet, run below CLI command to install it:

> npm install -g gulp

• Clone the project to you local workspace and navigate to the project home directory
• Run below CLI commands in sequence to build the project:

> npm install --save-dev
> bower install
> gulp

• Run below CLI to start the SPA in a local web server (default port to 3000):

> gulp serve

Your web browser will be promoted to access the URL http://localhost:3000. If it did not get promoted, try to manually access this URL in your web browser.

Goole Chrome and Mozilla Firefox are recommended. Microsoft Internet Explorer does not has the full support for HTML5 features demonstrated in this app.

4. Feature Overview

The sample application has a light API middleware src/app/filemanager/services/filemanager.middleware.js which calls Documentum REST JavaScript client to consume the REST services.

4.1 Sign in and sign out

This sample application implements a very simple sign-in and sign-out process based on HTTP basic authentication.

Sample code in API middleware src/app/filemanager/services/filemanager.middleware.js

ApiMiddleware.prototype.login = function () {
    var loginInfo = {
    baseUri: fileManagerConfig.rootContext,
    repoName: fileManagerConfig.repositoryName,
    username: fileManagerConfig.username,
    password: fileManagerConfig.password
    }
    return dctmClient.login(loginInfo).then(function () {
    fileManagerConfig.signedin = true
    })
}

ApiMiddleware.prototype.logout = function () {
    return dctmClient.logout().then(function () {
    fileManagerConfig.signedin = false
    })
}

4.2 Content functions

This smaple application impelments below content operations:

• Folder navigation
• Create folder
• Import document
• Preview content
• Download content
• Edit textual content online
• Rename
• Copy
• Move
• Delete
• Full-text search
• Pagination
• Permission management

Sample code in API middleware src/app/filemanager/services/filemanager.middleware.js

ApiMiddleware.prototype.listRootCabinets = function (pageNumber, itemsPerPage) {
    var repository = dctmClient.getCachedRepository()
    return dctmClient.getCabinets(repository,
    dctmConstants.QUERY_PARAMS.INLINE, true,
    dctmConstants.QUERY_PARAMS.PAGE, pageNumber,
    dctmConstants.QUERY_PARAMS.ITEMS_PER_PAGE, itemsPerPage)
}

ApiMiddleware.prototype.listFolderChildren = function (parent, pageNumber, itemsPerPage) {
    var viewAttrs = 'r_object_id,r_object_type,object_name,r_modify_date,r_creation_date,i_folder_id,r_full_content_size,a_content_type'
    return dctmClient.getChildObjects(parent,
    dctmConstants.QUERY_PARAMS.INLINE, true,
    dctmConstants.QUERY_PARAMS.VIEW, viewAttrs,
    dctmConstants.QUERY_PARAMS.PAGE, pageNumber,
    dctmConstants.QUERY_PARAMS.ITEMS_PER_PAGE, itemsPerPage)
}

ApiMiddleware.prototype.createFolder = function (parent) {
    var newFolder = { properties: { object_name: parent.name }}
    return dctmClient.createFolder(parent.object, newFolder)
}

4.3 Error handling

For an invalid operation, the error detail will be reported on the UI directly.

Sample code at src/app/filemanager/templates/modals.html

<script type="text/ng-template" id="error-bar">
  <div class="label label-danger error-msg pull-left animated fadeIn" ng-show="apiMiddleware.error">
    <i class="glyphicon glyphicon-remove-circle"></i>
    <span>{{apiMiddleware.error}}</span>
  </div>
</script>
