Running and Debugging a Meteor Application

The Meteor build tool

When we type meteor run at the command line to run our application, a lot happens behind the scenes to ensure that our application is built.

When we type meteor run in the command line to run our application, a lot happens behind the scenes to ensure that our application is built. The Meteor build tool is called Isobuild and is responsible for bundling our source code into runnable programs. Typing meteor run triggers the build tool, which goes through the following stages to build and run our project:

• Reads project metadata
• Initializes the version file
• Resolves constraints
• Downloads missing packages
• Builds local packages
• Saves changed metadata

Reading project metadata

Every Meteor application has a .meteor folder used to store metadata.
