General guidelines for contributing code

You are very welcome to contribute to the project! Pull requests welcome, as well as issues or plain messages.

Respect the below and I will be happy to merge your work and credit you for it.

Style and structure

  • Follow the style and conventions already in place. Figmagic uses Typescript and attempts to do some sort of Clean Architecture.
  • As always, write clean, easy-to-read code. Prefer being slightly more verbose and semantic than being "efficient" and terse, if such a choice is necessary. Write as if someone is going to contribute on top of your code base tomorrow without knowing you or your work.
  • Follow importing by highest-level components at top, and detail-oriented components at bottom. Example:
import { FRAME as Frame } from '../../../contracts/Figma';
import { BorderWidthTokens } from '../../../contracts/Tokens';

import { makeBorderWidthTokens } from '../index';

import { camelize } from '../../../frameworks/string/camelize';

import {
  ErrorMakeBorderWidthTokensNoFrame,
  ErrorMakeBorderWidthTokensNoChildren,
  ErrorMakeBorderWidthTokensMissingProps
} from '../../../frameworks/errors/errors';
  1. Entities
  2. Contracts
  3. Use cases or other high-level files
  4. Same-level files
  5. Frameworks
  6. Messages, errors, warnings (separated)

Tests

  • Always include tests for additions or changes. Aim for 100% coverage, but set a minimum bar to cover at least the main functionality. Figmagic should ideally have total code coverage of 95% or more. Your contribution will affect that score, so aim to keep it high(er)! :)
  • It's encouraged to place any test data in the __tests__/testdata/ folder.
  • Always check that all tests (including your new ones) are passing before making a pull request.
  • With the current GitHub Actions setup, your build there will fail since there is no access to my NPM credentials for non-master branches. Don't be alarmed! Again, ensure tests are passing and I can easily verify it in the build output.

Error handling

  • Make sure to handle errors and do any relevant validation logic. Also always output meaningful, actionable messages/warnings/errors to the user.
  • Avoid inlining messages, errors or warnings. Instead place those in the dedicated files for each of the mentioned concerns, and read them from there.

Documentation

  • Document your code with JSDoc at the start of your code. Since Figmagic uses Typescript, add "description" documentation; more than that is not needed.
  • Add any inline comments as needed for anything that is not self-evident.
  • Update the README with any user-facing changes, such as new CLI commands or arguments.
