esBuild not creating type files when in watch mode-CodePudding

Have recently started using edBuild, have found it simple, fast and easy to onboard.

When i run my esBuild build command WITHOUT WATCH I can see type files are successfully created - .d.ts files.

When WATCH IS running, these files are not generate.

package.json:

"scripts": {
    "ts-types": " tsc --emitDeclarationOnly --outDir dist",
    "build": " node ./esbuild.js && npm run ts-types",
    "postbuild": "npm run ts-types"
}

esbuild.js

.build({
    entryPoints: ['/index.ts'],
    outdir: 'dist',
    format: 'cjs',
    watch: {
        onRebuild(err, result) {
            if(err) log('error')
            else log('succes')
        }
    }
})
.then(result => {
    log('succes')
})
.catch(() => process.exit(1));

How can i run watch and recreate the .d.ts files on changes?

CodePudding user response：

ESBuild doesn't support generating type declaration.

You are using tsc to actually generate the type declaration.

You should be able to start a process from inside node that runs this. Something similar to this:

const {exec} = require('child_process');

...

.build({
    entryPoints: ['/index.ts'],
    outdir: 'dist',
    format: 'cjs',
    watch: {
        onRebuild(err, result) {
            if(err) log('error')
            else {
              exec("npm run ts-types");
            }
        }
    }
})
.then(result => {
    log('succes')
})
.catch(() => process.exit(1));
