write-yaml-file

What is write-yaml-file?

The write-yaml-file npm package allows you to write YAML files easily from JavaScript objects. It is useful for configuration management, data serialization, and other tasks where YAML is preferred over JSON or other formats.

What are write-yaml-file's main functionalities?

Write a simple YAML file

This feature allows you to write a simple YAML file from a JavaScript object. The code sample demonstrates how to create a YAML file named 'output.yaml' with basic user information.

const writeYamlFile = require('write-yaml-file');

const data = {
  name: 'John Doe',
  age: 30,
  occupation: 'Software Developer'
};

writeYamlFile('output.yaml', data).then(() => {
  console.log('YAML file written successfully!');
});

Write a nested YAML file

This feature allows you to write a nested YAML file from a JavaScript object. The code sample demonstrates how to create a YAML file named 'nested_output.yaml' with nested user information.

const writeYamlFile = require('write-yaml-file');

const data = {
  user: {
    name: 'Jane Doe',
    details: {
      age: 28,
      occupation: 'Data Scientist'
    }
  }
};

writeYamlFile('nested_output.yaml', data).then(() => {
  console.log('Nested YAML file written successfully!');
});

Write a YAML file with custom options

This feature allows you to write a YAML file with custom options such as indentation. The code sample demonstrates how to create a YAML file named 'custom_output.yaml' with a custom indentation of 4 spaces.

const writeYamlFile = require('write-yaml-file');

const data = {
  name: 'Alice',
  age: 25,
  occupation: 'Graphic Designer'
};

const options = {
  indent: 4
};

writeYamlFile('custom_output.yaml', data, options).then(() => {
  console.log('YAML file with custom options written successfully!');
});
