Hi, in this post, we'll create trash program by
JS
,
after create it, this program will be npm package.
Pre-requisites
before we move on, you'll need :
Let's go
We're going to create package.json
The first command is npm init
$ npm init
I'll name it manx
so you should have like this ...
{ "name": "@your_npm_user_name/your_proj_name", "version": "1.0.0", "description": "Cli app can move files/folders to the trash without any dangerous", "main": "cli.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "repository": { "type": "git", "url": "https://Git_Repos_Site/Your_Git_Repo" }, "keywords": [ "cli-app", "cli", "trash" ], "author": "Your_Name", "license": "ISC" }
We don't want to have package-lock.json
, so type
$ touch .npmrc
in
.npmrc
package-lock=false
now we'll install @abdfnx/hac_k & trash
$ npm i @abdfnx/hac_k trash
ok, let's create cli.js
in
cli.js
#!/usr/bin/env node "use strict";
now we're going to require the packages
#!/usr/bin/env node "use strict"; const hac_k = require("@abdfnx/hac_k"); const manx = require("trash");
nice, also create two variables
// Ignore all flags of `rm` program. const ignoredFlags = ["r", "f", "i", "d", "P", "R", "v", "W"]; const ignoredFlagsConfig = {};
this variables're very important, so we'll make for
loop
for (const flag of ignoredFlags) { ignoredFlagsConfig[flag] = { type: "boolean", }; }
the most importnant variable is cli
const cli = hac_k( ` Usage $ manx <file/folder> […] Examples # file $ manx xcode.tsx layout.tsx edge.tsx $ manx '*.tsx' '!xcode.tsx' # folder $ manx app `, { flags: { ...ignoredFlagsConfig, }, } );
But what if the user entered a space, we need if
statement
if (cli.input.length === 0) { console.error("Specify at least one path"); process.exit(1); }
at the end add
manx(cli.input);
the final result of file
#!/usr/bin/env node "use strict"; const hac_k = require("@abdfnx/hac_k"); const manx = require("trash"); // Ignore all flags of `rm` program. const ignoredFlags = ["r", "f", "i", "d", "P", "R", "v", "W"]; const ignoredFlagsConfig = {}; for (const flag of ignoredFlags) { ignoredFlagsConfig[flag] = { type: "boolean", }; } const cli = hac_k( ` Usage $ manx <file/folder> […] Examples # file $ manx xcode.tsx layout.tsx edge.tsx $ manx '*.tsx' '!xcode.tsx' # folder $ manx app `, { flags: { ...ignoredFlagsConfig, }, } ); if (cli.input.length === 0) { console.error("Specify at least one path"); process.exit(1); } manx(cli.input);
you're good, now let's test it, go to package.json
and add bin
, engines
, files
props
{ "name": "@your_npm_user_name/your_proj_name", "version": "1.0.0", "description": "Cli app can move files/folders to the trash without any dangerous", "main": "cli.js", "bin": { "manx": "cli.js" }, "engines": { "node": ">=10" }, "files": [ "cli.js" ], "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "repository": { "type": "git", "url": "https://Git_Repos_Site/Your_Git_Repo" }, "keywords": [ "cli-app", "cli", "trash" ], "author": "Your_Name", "license": "ISC", "dependencies": { "@abdfnx/hac_k": "^1.0.2", "trash": "^7.0.0" } }
type npm link
$ npm link
add file and folder for test
$ touch test_file && mkdir test_folder
Now the awaited moment, in the terminal
$ manx --help Usage $ manx <file/folder> […] Examples # file $ manx xcode.tsx layout.tsx edge.tsx $ manx '*.tsx' '!xcode.tsx' # folder $ manx app $ manx test_file test_folder
Congratulations, you now have a great program...
npm publish
(optional)
if you want to publish your awesome project to npm, follow me
before publish, add some files
.editorconfig
, .gitattributes
, .gitignore
and .travis.yml
it's optional, but it's better to create it
in .editorconfig
root = true [*] indent_style = tab end_of_line = lf charset = utf-8 trim_trailing_whitespace = true insert_final_newline = true [*.yml] indent_style = space indent_size = 2
.gitattributes
* text=auto eol=lf
.gitignore
node_modules yarn.lock
.travis.yml
language: node_js node_js: - '14' - '12' - '10'
ok, type
$ npm unlink
and now we must login to npm
$ npm login
publish
$ npm publish --access=public
and if you want to install it, you should install it globally
$ npm i -g YOUR_PKG
you can see your package in npm
visit https://www.npmjs.com/package/YOUR_PKG
Here you are, you have trash program and npm package...
enjoy, and see you next time.
