• Custom Templates: Use custom templates for the output file.
• Locale Support: Supports different locales for timestamp formatting (e.g., en, fa).
• CLI and Programmatic Use: Can be used as a command-line tool or imported as a module in your Node.js projects.

Installation

You can install Timestamper globally for CLI use or locally in your project.

Global Installation

2. Add a timestamp to a custom output file with a specific format:

   ts -l en -o result.json -f YYYYMMDDHHmmss

3. Use a custom template file:

   ts -l fa -o result.json -t template.txt

4. Use an inline template:

   ts -l fa -o result.json -i "{ test: '{ts}' }"

5. Get help:

   ts --help

Programmatic Use

You can also use Timestamper as a module in your Node.js projects.

Example 1.

const { Timestamper } = require('@puya/ts');

const result = Timestamper({
    locale: 'en',
    outputFileName: 'result.json',
    template: '{ "hash": "{ts}" }',
    format: 'YYYYMMDDHHmmss'
});

if (result.success) {
    console.log(`Timestamp "result.json" generated successfully`);
} else {
    console.error('Failed to generate timestamp:', result.err);
}

Example 2. No output

const { Timestamper } = require('@puya/ts');

const result = Timestamper({
    locale: 'en',
    skipOutput: true,
    template: '{ "hash": "{ts}" }',
    format: 'YYYYMMDDHHmmss'
});

if (result.success) {
    console.log('Timestamp: ', result.data);
} else {
    console.error('Failed to generate timestamp:', result.err);
}
