A function that logs the difference between two objects. The differences are printed in a Github-looking style. If you have 2 objects - left and right:
const left = {
name: 'first object',
nested: {
cool: false,
old: 'fashion',
list: ['one', 'two'],
},
you: {
cant: {
touch: 'this',
},
},
};
const right = {
name: 'second object',
nested: {
cool: true,
list: ['one', 'two', 'three'],
},
}
logDiff(left, right);
logDiff would print the following:
Keep in mind the order of the arguments for the diff - from the Left Hand Side (lhs) to the Right Hand Side (rhs) - logDiff(lhs, rhs)
logDiff is exported in the dist folder as:
- CommonJS module (cjs)
- ES module (esm)
- UMD build (umd)
One fast way to use logDiff straight in the browser is to import the ES module version with dynamic module imports. This is supported by newer versions of Chrome, Firefox, Safari and Edge - see caniuse.com.
This way logDiff can be loaded like so:
(async () => {
try {
// Specify where logdiff.esm.js is located
const scriptUrl = 'https://logdfiff.firebaseapp.com/logdiff.esm.js';
const { default: logDiff } = await import(scriptUrl);
window.logDiff = logDiff;
console.log('logDiff loaded!');
} catch (err) {
console.log(err);
}
})();
Check examples/index.html for example usage.
For developing logDiff the dependencies can be installed with yarn or npm:
yarn
# or
npm install
To transpile and bundle run the following:
yarn build
# or
npm run build
To watch for file changes and trigger a new build:
yarn dev
# or
npm run dev
