Meteor
Meteor is a full-stack framework that lets you use JavaScript both on the client-side and on the server-side. IntelliJ IDEA integrates with Meteor so you can use it from inside the IDE. Meteor support in IntelliJ IDEA includes:
Automatic recognition of Meteor projects by detecting the
.meteor
folder and excluding the.meteor/local
folder from project. See Hiding excluded files for details.Attaching the predefined Meteor library to the project automatically. This enables syntax highlighting, resolving references, and code completion.
Support of Spacebars via Handlebars with completion for if and each directives. IntelliJ IDEA recognizes Spacebars templates, but as a side effect marks HTML files in Meteor projects with the Handlebars/Mustache icon . IntelliJ IDEA provides navigation between JavaScript source code and templates with go to Declaration (Ctrl+B).
A dedicated complex Meteor run/debug configuration for debugging both the client-side and the server-side code within one debugging session, see Debugging a Meteor application.
Before you start
Install and enable the Meteor and the Handlebars/Mustache repository plugins on the Plugins page as described in Managing Plugins.
Installing Meteor
The installation procedure depends on the operating system you are using. Learn more from the Meteor Official website.
To install Meteor on Windows
Download the
LaunchMeteor.exe
installer at the Meteor Official website.
To install Meteor on macOS or Linux
Open the embedded Terminal ( or Alt+F12) and type
$ curl https://install.meteor.com | /bin/sh
at the command prompt.
Creating a new Meteor application
If you have no application yet, you can generate a IntelliJ IDEA project with Meteor-specific structure from a Meteor boilerplate template. Alternatively, create an empty IntelliJ IDEA project and configure Meteor support in it as described in Starting with an existing Meteor application below.
To create a Meteor project from a boilerplate template
Choose New Project button on the Welcome screen.
on the main menu or click theIn the Project Category and Options dialog, which is the first page of the New Project wizard, choose Static Web in the left-hand pane.
In the right-hand pane, choose Meteor App and click Next.
- On the second page of the wizard:
Specify the project name and the folder to create it in.
Specify the location of the Meteor executable file (see Installing Meteor).
From the Template drop-down list, choose the sample to generate. To have a basic project structure generated, choose the Default option.
To create an empty IntelliJ IDEA project
Choose New Project button on the Welcome screen.
on the main menu or click theIn the Project Category and Options dialog, which is the first page of the New Project wizard, choose Static Web in the left-hand pane.
In the right-hand pane, again choose Static Web and click Next.
On the second page of the wizard, specify the project folder and name and click Finish.
Starting with an existing Meteor application
If you are going to continue developing an existing Meteor application, open it in IntelliJ IDEA, configure Meteor in it, and download the required dependencies as described in Downloading Meteor dependencies below.
To open the application sources that are already on your machine
Click Open on the Welcome screen or choose on the main menu. In the dialog that opens, select the folder where your sources are stored.
To check out the application sources from your version control
Click Check out from Version Control on the Welcome screen or choose on the main menu.
Select your version control system from the list.
In the VCS-specific dialog that opens, type your credentials and the repository to check out the application sources from.
To configure Meteor support in an existing project
In the Settings/Preferences dialog (Ctrl+Alt+S), click JavaScript under Languages and Frameworks, then choose Meteor. The Meteor page opens.
Specify the path to the Meteor executable file. If you followed the standard installation procedure, IntelliJ IDEA detects the file automatically.
To involve the
.meteor/local
folder and its contents in indexing, clear the Automatically exclude ".meteor/local" directory on open project checkbox. For details, see Hiding excluded files below.- Make sure the Automatically import Meteor packages as external library checkbox is selected.
When the checkbox is selected, IntelliJ IDEA automatically imports the external packages from the
meteor/packages
file. As a result, IntelliJ IDEA provides full range coding assistance: resolves references to Meteor built-in functions, for example,check(true)
, and to functions from third-party packages, provides proper syntax and error highlighting, supports debugging with source maps, etc.When this checkbox is cleared, IntelliJ IDEA does not automatically import the external packages from the
meteor/packages
file. As a result no coding assistance is provided. To improve the situation, open themeteor/packages
file in the editor and click the Import packages as library link or run themeteor --update
command.
Make sure IntelliJ IDEA has attached the Meteor library to the project.
In the Settings/Preferences dialog (Ctrl+Alt+S), click JavaScript under Languages and Frameworks, then choose Libraries. On the JavaScript. Libraries page opens, make sure the checkbox next to the Meteor project library in the Libraries list is selected.
Importing Meteor packages
Besides the predefined Meteor library that ensures basic Meteor-specific coding assistance, you can download additional packages that are defined in the .meteor/local/packages
file.
To download additional Meteor packages
Open the
.meteor/local/packages
file in the editor.Click the Import Meteor Packages link in the upper right-hand corner of the screen.
- In the dialog box that opens, specify the packages to download depending on the type of the application you are going to develop in your project.
- Client
- Server
Cordova: choose this option to import the packages that support development of Meteor applications for iOS and Android, see Meteor Cordova Phonegap Integration for details.
IntelliJ IDEA automatically marks the .meteor/local folder, which is intended for storing the built application, as excluded but still shows it in the project tree.
To hide the .meteor/local folder
Click the button on the toolbar of the Project tool window and remove a tick next to the Show Excluded Files option.
Running a Meteor application
IntelliJ IDEA runs Meteor applications according to a run configuration of the type Meteor. If you created your application from a boilerplate template, IntelliJ IDEA generates a Meteor run configuration for you.
To create a Meteor run configuration
On the main menu, choose Meteor from the list. The Run/Debug Configuration: Meteor opens.
, click and chooseIn the Configuration tab, specify the path to the Meteor executable file according to the installation (see Installing Meteor).
Specify the folder under which the application files to run are stored. This folder must have a
.meteor
subfolder in the root so IntelliJ IDEA recognizes your application as a Meteor project. By default, the working directory is the project root folder.
Optionally
In the Program Arguments field, specify the command line additional parameters to be passed to the executable file on start up, if applicable. These can be, for example,
--dev
,--test
, or--prod
to indicate the environment in which the application is running (development, test, or production environments) so different resources are loaded on start up.By default, IntelliJ IDEA shows the application output in the Run tool window. To view the results of the client-side code execution, in the Browser / Live Edit tab select the After Launch checkbox and choose the browser to open from the drop-down list. In the text box below, specify the URL address to open the application at. The default value is
http://localhost:3000
.
To run a Meteor application
Select the required run configuration from the list on the main tool bar and then choose Run .
on the main menu or clickView the application output in the Run tool window or in the browser if you configured the browser to open on application start as described above.
Debugging a Meteor application
With IntelliJ IDEA, you can debug both the client-side and the server-side of Meteor JavaScript code within one debugging session. A debugging session is initiated only through a dedicated Meteor run configuration.
Technically, several Meteor projects that implement different applications can be combined within one single IntelliJ IDEA project. To run and debug these applications independently, create a separate run configuration for each of them with the relevant working directory. To avoid port conflicts, these run configurations should use different ports. In the Program Arguments field, specify a separate port for each run configuration in the format --port=<port_number>
.
To debug a Meteor application
Set the breakpoints in the code where necessary.
Create a Meteor run/debug configuration as described above. In the Browse / Live Edit tab, select the After launch checkbox, choose Chrome from the list, and select the with JavaScript debugger checkbox.
To initiate a debugging session, select the required debug configuration from the list on the main tool bar and click next to the list or choose Debug tool window opens showing two tabs: one for debugging the server-side code marked with and the other one for debugging the client-side code marked with .
. The
Previewing changes in the browser
During a debugging session, you can preview changes to your HTML, CSS, or JavaScript code on the fly. The live contents of the page you edit are shown in the Elements
tab of the Debug tool window. The update policy depends on which part of your application you are editing.
To preview changes to the client-side code, do one of the following:
Switch to the <Configuration name> JavaScript tab and click on the toolbar.
Configure automatic upload of updates by selecting the Enable Meteor Hot code push checkbox on the Meteor page. Learn more from the Meteor Official website.
To preview the changes to the server-side code, dop one of the following:
Switch to the <Configuration name> tab and click on the toolbar.
Configure automatic upload with the Live Edit functionality as described in Live Edit in HTML, CSS, and JavaScript. It is recommended that you select the Restart if hotswap fails checkbox on the Live Edit page, then IntelliJ IDEA will attempt to restart the server when automatic upload fails.
