Introduction to Prebuild

Prebuild is a crucial tool for developers to streamline the process of managing dependencies and building modules. This guide covers its introduction and explains several useful APIs with practical code snippets to demonstrate their application.

Prebuild.install API

The install API is used to download and install prebuilt binaries. It simplifies the installation process and ensures that the binaries are compatible with different environments.

    const prebuild = require('prebuild');
    prebuild.install({ path: './path-to-module', runtime: 'node' }, (err) => {
      if (err) console.error(err);
      else console.log('Prebuilt binary installed successfully');
    });
  

Prebuild.build API

The build API is utilized to build binaries from source code. It’s an essential part of the development process, particularly when you need to generate platform-specific binaries.

    const prebuild = require('prebuild');
    prebuild.build({ path: './path-to-module', napi: true }, (err) => {
      if (err) console.error('Build failed', err);
      else console.log('Build successful');
    });
  

Prebuild.upload API

The upload API comes in handy when you need to upload prebuilt binaries to a server or a storage service. This enables easy sharing and distribution of binaries.

    const prebuild = require('prebuild');
    prebuild.upload({ path: './prebuilt-binaries', to: 's3://mybucket' }, (err) => {
      if (err) console.error('Upload failed', err);
      else console.log('Upload successful');
    });
  

Prebuild.download API

The download API is used to download prebuilt binaries from a specified location. This is particularly useful for setting up development environments quickly.

    const prebuild = require('prebuild');
    prebuild.download({ url: 'http://example.com/prebuilt-binary' }, (err, binary) => {
      if (err) console.error('Download failed', err);
      else console.log('Download successful', binary);
    });
  

Application Example

Below is a sample application demonstrating the use of the above prebuild APIs.

    const prebuild = require('prebuild');

    function setupModule() {
      prebuild.install({ path: './my-module', runtime: 'node' }, (err) => {
        if (err) return console.error(err);

        prebuild.build({ path: './my-module', napi: true }, (err) => {
          if (err) return console.error(err);

          prebuild.upload({ path: './my-module/prebuilt-binaries', to: 's3://mymodulebucket' }, (err) => {
            if (err) return console.error(err);
            console.log('Module setup complete and binaries uploaded');
          });
        });
      });
    }
    
    setupModule();
  

By following the above steps, developers can optimize their workflow with ease.
