Burstmake

Burstmake is a tool to manage your TypeScript project when there are more indipendent parts. In this case, the solution is either creating one tsconfig.json file for each subpart or using another tool to have a pretty manage. Burstmake wants to simplify everything using one file: burstmake.json.

Sections

Installing and use

For the latest stable version:

npm install -g burstmake

and run:

burstmake

in the root of project to create the tsconfig.json files from burstmake.json file.

Summary

Imagine a project as below:

root
|-- front 
|   |-- src
|   |-- test
|    
|-- back
    |-- src
    |-- test

now, to compile all the four parts you need a tsconfig.json file for front/src, front/test, back/src and back/test, which have the options to translate from TypeScript to JavaScript.

This is a mistake! In the worst case you have the same options for four files.

As said above, Burstmake wants to bring a new, better, solution.

Before explaining what to do, we must introduce the concept of topic and hotpoint.

Topic

The topic is the set of TypeScript rules to apply to the hotpoint. One topic has the same content of a TypeScript configuration but with some differences.

The most important property of a topic is the possibility to extend it for creating a hierarchy of topics, in this way the problem of making multiple tsconfig files with the same options is resolved.

Another property of topics is that the paths are relative to the root of the project. This is very useful and it doesn't meet the tedious problem to resolve pesky relative path.

The example below shows how to write a topic:

{
    "common": {
        "compilerOptions": {
            "target": "es5",
            "noImplicitAny": true,
            "removeComments": true,
            "preserveConstEnums": true,
            "sourceMap": true
        }
    },

    "front_t": {
        "base": "common",
    
        "compilerOptions": {
            "module": "amd",
            "outFile": "built/app.js"
        }
    },
    
    "back_t": {
        "base": "common",
        
        "compilerOptions": {
            "module": "commonjs"
        }
    }
}

When Burstmake runs, front_t and back_t will inherite all compiler options from common topic. If a declaration is both in a parent topic and in a children topics, the children topic's declaration will be used. In the case above, front_t and back_t become:

{
    "front_t": {
        "compilerOptions": {
            "target": "es5",
            "noImplicitAny": true,
            "removeComments": true,
            "preserveConstEnums": true,
            "sourceMap": true,
            "module": "amd",
            "outFile": "built/app.js"
        }
    }
}
{
    "back_t": {
        "compilerOptions": {
            "target": "es5",
            "noImplicitAny": true,
            "removeComments": true,
            "preserveConstEnums": true,
            "sourceMap": true,
            "module": "commonjs"
        }
    }
}

Hotpoint

Alright, now we have learned how to write a topic and use inheritance to avoid multiple similar tsconfig.json files, how do we specify the subsets of the project in which we want to use it?

Well, is simple. In the burstmake.json file there must be an 'hotpoint' attribute in which is stated the association topic-folder.

This is an example:

{
    "hotpoint": {
        "front_t": "./front/",
        "back_t": "./back/"
    },

    "common": {
    
    },
    
    "front_t": {
    
    },
    
    "back_t": {
    
    }
}

If you run burstmake in the front/ and back/ directory you should find a tsconfig.json file with the correct configuration. As you can see the common topic is not inserted in the hotpoint section, it is only a topic from which taking information about the common configurations.

Note: the / is important, make sure you won't forget it.

Schema

The structure of burstmake.json file is:

{
    "hotpoint": {
        "topic_declared": "path_with_final_slash"
    },
    
    "topic": {
        "base": "some_topic",
        
        "compilerOptions": {
        },
        
        "include": [
            "file outside of topic, useful for .d.ts definitions"
        ],
        
        "exclude": [
            "use minimatch expression to ignore files or 
	    directories in the topic folder"
        ],
    }
}

The compilerOptions attribute is the compilerOptions of a tsconfig.json file but for now it supports only:

  • module
  • target
  • moduleResolution
  • noImplicitAny
  • removeComments
  • preserveConstEnums
  • outDir
  • outFile
  • sourceMap
  • declaration
  • noEmitOnError

IMPORTANT: The paths in hotpoint and compilerOptions must use the format: ./path/, instead the paths in include must be in the path/source format.
