如何通知用户 NPM 包版本更新?
How to notify NPM package version update to user?
我用 Node JS 编写了一个 CLI 工具并发布到 NPM。每次在终端中出现 运行 时,我都需要通知用户可用的新版本及其类型(补丁 | 次要 | 主要),以便 he/she 可以相应地更新它。我该如何实施?
此外,是否可以询问用户he/she是否希望自己更新包?

版本更新检查:
我建议使用 update-notifier 但奇怪的是它不起作用。所以,我选择了自己来完成这项工作。
可以使用 package-json which fetches the metadata of a package from the npm registry. Alternatively latest-version 轻松检查最新版本,也可以使用 package-json。
import boxen from 'boxen';
import chalk from 'chalk';
import semver from 'semver';
import pkgJson from 'package-json';
import semverDiff from 'semver-diff';
import { capitalizeFirstLetter } from '../utils';
import { name, version } from '../../package.json';
const checkUpdate = async () => {
const { version: latestVersion } = await pkgJson(name);
// check if local package version is less than the remote version
const updateAvailable = semver.lt(version, latestVersion as string);
if (updateAvailable) {
let updateType = '';
// check the type of version difference which is usually patch, minor, major etc.
let verDiff = semverDiff(version, latestVersion as string);
if (verDiff) {
updateType = capitalizeFirstLetter(verDiff);
}
const msg = {
updateAvailable: `${updateType} update available ${chalk.dim(version)} → ${chalk.green(latestVersion)}`,
runUpdate: `Run ${chalk.cyan(`npm i -g ${name}`)} to update`,
};
// notify the user about the available udpate
console.log(boxen(`${msg.updateAvailable}\n${msg.runUpdate}`, {
margin: 1,
padding: 1,
align: 'center',
}));
}
};
更新通知:
每次该工具运行时,如果有可用更新,用户会看到这样的通知。
