TS-Bundler
This is a (super) lightweight typescript bundle library, which I created for my build tool @puresamari/spb since webpack creates way too much overhead.
Installation
npm i[nstall] [--save[-dev]|-D|-S] @puresamari/ts-bundler
Usage
import { TypescriptBundler } from '@puresamari/ts-bundler';
...
// Create the bundler with the file as attribute (file has to be an absolute path)
const bundler = new TypescriptBundler(file);The bundlers observe method returns a rxjs observable that contains the following values:
interface {
output: string,
map: Map<string, {
content: string;
node_module: boolean;
file: string;
absolutePath: string;
}>
}The observe method takes 2 oparameters:
- Rebundle: should the bundle be compiled when running observe() (default = true)
- Once, should you only get the first trigger. (default = false)
Example use cases
(To run these please first create a bundler instance like above.)
The examples compile file into test.export.js.
Bundle the module:
import fs from 'fs';
const result = bundler.observe().subscribe(({ output }) => {
fs.writeFileSync(path.resolve(__dirname, 'test.export.js'), v.output);
});The same but with file watching and module replacement:
import fs from 'fs';
const result = bundler.observe().subscribe(({ output }) => {
fs.writeFileSync(path.resolve(__dirname, 'test.export.js'), v.output);
});
bundler.observe(false, true).subscribe(v => {
v.map.forEach((v, _module) => {
if (!v?.file || v.node_module) { return; }
fs.watchFile(v.absolutePath, () => {
bundler.refreshModule(_module);
})
})
});
Bundle once using await:
import fs from 'fs';
fs.writeFileSync(path.resolve(__dirname, 'test.export.js'), await bundle.bundle().output);Bundle once using promise:
import fs from 'fs';
bundle.bundle().then(({ output }) => fs.writeFileSync(path.resolve(__dirname, 'test.export.js'), output);
