npm install --save koa-asar

const Asar = require("koa-asar");
const Koa = require("koa");
const app = new Koa();

app.use(Asar(archive, options));

app.listen(3000);
console.log("listening on port 3000");

• archive - The path to the ASAR file.
• options - Configuration options:
• root - The website root directory, which can be understood as the URL prefix. Default value: /.
• methods - HTTP methods to handle. Default value: ['GET'].
• rewrite - File rewrite rules. The current value can be a function/object/string.
• index - The default document name.
• maxage - Cache duration. Unit: seconds.
• maxAge - Same as maxage.
• default - When the loaded file does not exist, then load the file configured for the current setting.

• When the parameter is a function, the signature is as follows: rewrite(filename): Promise<string>.
• When the parameter is an object, the key is the matched file name, and the value is the rewritten file name.
• When the parameter is a string, any URL will return fixed file content.
