Try any Node.js package right in your browser

This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 400,000 packages pre-installed, including @sketchmine/code-analyzer with all npm packages installed. Try it out:

var codeAnalyzer = require("@sketchmine/code-analyzer")

@sketchmine/code-analyzer v3.0.0

Pulls out the information from a source code and provides an abstract representation in JSON format about the code.

Note: This is a Dynatrace internal tool that may not fit your needs.

The code-analyzer works like a compiler, analyzing the provided source code of the Angular Component Libraries and generating an abstract syntax tree (AST) from the Angular components. The output of the meta information is provided in JSON format and contains all information about all the components in the library and their variants.

This solution is currently tailored for the Dynatrace Angular Component Libraries. Feel free to commit a pull request with your solution for your company.

Dependency graph

Dependency graph of the sketchmine code-analyzer


First, you need the Angular Component Libraries source code. You can easily run a sh ./src/code-analyzer/ script, which takes care of this for you.

Afterward, run the rollup build in one window: npm run build:dev this will start rollup in watch mode with cokidar to compile the .ts files on the file in the specified dist folder (specified in ./config/build.js). The compiled output can easily be started with node dist/code-analyzer. The possible command line arguments for the application are written as default values in the ./src/code-analyzer/config.json. The commandline arguments overwrite the defaults from the JSON.

Command line arguments

-h, --help              | display help
-c, --config            | path to the configuration file
--rootDir               | root dir of the angular components library
--library               | path to lib folder where the components are located from root
--inFile                | index.ts file as entry point for the lib
--outFile               | the file that holds the meta-information – as .json

  • Are there specific versions required?

Annotations for the code

It's possible to add JSDoc annotations that are specific for the generation of the meta information abstraction of the library in case some properties are filled with values or classes that can be ignored for design unrelated stuff.

// TODO: add optional selector to click and hoverable, to specify a trigger for clicking!

@internalMarks property, class, ..., as internal and will be ignored. The same like private class members.
@design-unrelatedMarks property, class, ..., as unrelated for the design system and will be ignored by the parser.
@design-hoverablethe component is hoverable
@design-clickablethe component is clickable
@design-prop-value "UNIQQUE_ID_FOR_ELEMENT"bind a custom value to a property. can be even a complex object or a number, string, etc.. see Regex
@design-param-value propToBeBinded {obj: "asdf"}bind a custom value to a specific param. can be even a complex object or a number, string, etc.. see Regex
@no-design-combinationsDoes not combine all the properties together and did not generate all possible combinations.
@design-action-timeoutUses a delay for drawing, if an action should be performed like an animation.

How to install

Just run npm i in the root.

How to develop

For debbugging, you can specify specific debug spaces with DEBUG=${space1},${space2},${space3}... node code-analyzer or just set DEBUG to true.

Available debug spaces for granular logging:

  • annotations

How to run tests

There are ts-lint and compiler rules. Just run npm run lint.

For tests, the Jest framework was selected. Just run npm run test
