express-open-in-editor

Express extension to open any file in an editor. Based on open-in-editor.

Install

npm install express-open-in-editor

Usage

var express = require('express');
var openInEditor = require('express-open-in-editor');

var app = express();

app.use(openInEditor());

// ...

After that you can use GET requests like /open-in-editor?file=foo/bar.ext:2:5 to open foo/bar.ext in an editor at line 2 column 5.

By default extension uses process.env.VISUAL or process.env.EDITOR (with this priority) to get the command to open file in an editor. It could be set globally or with main script:

EDITOR=subl node app.js

Also you can set process.env.OPEN_FILE that has highest priority and understands shorthands (i.e. subl for Sublime Text or atom for Atom Editor).

For more details about editor setup see open-in-editor.

Using with webpack-dev-server

Although webpack-dev-server uses express to create server, you can't use app.use() to apply extension. Instead you should define it in setup method (see issue for details).

var server = new WebpackDevServer(webpack(config), {
  // ...
  setup: function(app) {
    app.use(openInEditor());
  }
});

API

openInEditor([options]);

options

url

Type: String

Default: /open-in-editor

Request to this path triggers middleware.

editor

Type: String

Values: sublime, atom, code

Default: not set

Editor to open files. Option accepts one of preset values. When value is set, extension tries to detect command to launch an editor.

Supported editors:

• sublime – Sublime Text
• atom – Atom Editor
• code – Visual Studio Code

cmd

Type: String

Default: not set

Command to launch an editor. This option overrides whatever is set in editor option.

Command could contain placeholders that will be replaced with actual values. Supported placeholders: filename, line and column.

app.use(openInEditor({
  cmd: 'code -r -g {filename}:{line}:{column}'
}));

If no {filename} placeholder is present, then {filename}:{line}:{column} is appended to the value of this option. That way previous example could be simplified:

app.use(openInEditor({
  cmd: 'code -r -g'
}));
