Easily move files and directories around your JavaScript project.
The problem
Moving JavaScript modules inside a project is generally a tedious task.
After you move it using mv, you have to update their references on the
other modules inside your project.
mvjs moves the module and also updates all its references on the other modules
making the task of moving modules much simpler, similarly to using mv.
It does this by running a codemod on all JavaScript modules inside the project
(with the help of jscodeshift) and smartly updating import declarations and
require calls.
For non-js module files, a regular expression runs on their content, replacing
any string that looks like a path and matches any of the moved files will be
properly replaced. This gives extra piece of mind when moving .scss and other
file extensions that can potentially import one of the moved files.
Features
- Supports and updates
import _ from '...',import('...')andrequire('...') - Updates files using JavaScript, TypeScript or Flow
- Does its best to also update non-js files
- Moves files or directories
- Same api and simplicity of the
mvcommand - Shows easy to understand errors when unexpected things happen
- Uses
DEBUGenvironment variable to show extra dbug information. Ex:DEBUB=* mvjs ./a.js ./b.js
Install
npm install -g @fabiomcosta/mvjs
This makes mvjs available globally.
CLI Usage
$ mvjs --help
mvjs - moves a JavaScript module and updates all import references in the project.
Options:
--version Show version number [boolean]
--parser jscodeshift's parser option.
See https://github.com/facebook/jscodeshift#parser [string] [default: "flow"]
--ignore-pattern Pattern of files that won't have their file references updated [string]
--help Show help [boolean]
Examples:
cli.js ./a.js ./b.js Moves "a.js" to "b.js" and updates the other modules
importing "a.js" to now import "b.js".
cli.js --recast.quote='double' ./a.js ./b.js Recast options can be changed by using
--recast.optionName notation.
In this example the codemoded files are going to have
double quotes for all strings.
See https://github.com/benjamn/recast/blob/master/lib/op
tions.ts
cli.js --ignore-pattern='*.d.ts' Ignore patterns with the familiar gitignore syntax
--ignore-pattern='*.js.flow' ./a.js ./b.js defined at https://git-scm.com/docs/gitignore
Multiple patterns can be ignored by providing multiple
options.
Example
Consider the following folder structure for a project:
root/
│ package.json
└── src/
├── common/
│ └── config.js
└── client/
│ paths-client.js
└── files-client.js
And the following file content for ./src/client/paths-client.js:
import files from './files-client';
// or const files = require('./files-client');Let's move the ./src/client/files-client.js module inside the ./src/common/ folder:
mvjs ./src/client/files-client.js ./src/common/files.js
This will make sure that all files that had a reference to this module are also
going to be properly updated, which means that paths-client.js will be updated to:
import files from '../common/files';
// or const files = require('../common/files');API Usage
move (and ONLY move) modules:
import {move} from '@fabiomcosta/mvjs';
(async () => {
await move({
sourcePaths: ['./foo.js', './bar.mjs'],
targePath: './baz'
});
})();codemod the import statements from the current project modules:
import {transform} from '@fabiomcosta/mvjs';
(async () => {
await transform({
sourcePaths: ['./foo.js', './bar.mjs'],
targePath: './baz',
parser: 'flow', // optional
recastOptions: {quotes: 'single'} // optional
});
})();TODO
- move .jsx, .mjs, .es, .es6
- move multiple sources to a directory
- move a directory to another directory
- move any file extension (keep updating the references only from .js, .jsx, .mjs, .es, .es6 files)
- Update references on other types of files, like CSS, SASS, LESS etc.
- Optionaly rename imported default
- Add option to allow other function calls to be replaced
