Markdown driven task runner.
You can install Maid globally:
# For npm users
npm i -g maid
# For Yarn users
yarn global add maid
Or if you want to ensure that your teammates are using the same version as you, it's recommended to install Maid locally:
# For npm users
npm i -D maid
# For Yarn users
yarn add maid --dev
PRO TIP: you can use npx
or yarn
command to run any locally installed executable that is inside node_modules/.bin/
, e.g. use yarn maid
to run the locally installed maid command.
A maidfile is where you define tasks, in Markdown!
π maidfile.md:
## lint
It uses ESLint to ensure code quality.
```bash
eslint --fix
```
## build
Build our main app
<!-- Following line is a maid command for running task -->
Run task `build:demo` after this
```bash
# note that you can directly call binaries inside node_modules/.bin
# just like how `npm scripts` works
babel src -d lib
```
## build:demo
You can use JavaScript to write to task script too!
```js
const webpack = require('webpack')
// Async task should return a Promise
module.exports = () => new Promise((resolve, reject) => {
const compiler = webpack(require('./webpack.config'))
compiler.run((err, stats) => {
if (err) return reject(err)
console.log(stats.toString('minimal'))
resolve()
})
})
```
Each task is defined using h2
header and its child contents, the value of h2
header will be used as task name, its following paragraphs (optional) will be used as task description, and following code block (optional) will be used as task script.
Currently the code block languages are sh
bash
js
javascript
and more!.
Now run maid help
to display the help for this maidfile:
β― maid help
lint It uses ESLint to ensure code quality.
build Build our main app
build:demo You can use JavaScript to write to task script too!
β― maid help "build*"
build Build our main app
build:demo You can use JavaScript to write to task script too!
To run a task, you can directly run maid <task_name>
β― maid build
[13:46:38] Starting 'build'...
π Successfully compiled 3 files with Babel.
[13:46:38] Finished 'build' after 363 ms...

[13:46:38] Finished 'build:demo' after 734 ms...
# to get minimal logs
β― maid build --quiet
π Successfully compiled 3 files with Babel.

You can run tasks before or after a task:
## build
Run task `deploy` after this
```bash
webpack --config config/webpack.config.js
```
## deploy
```bash
gh-pages -d dist
```
Basically expressions like Run task `deploy` after this
is treated specially, in this case if you run maid build
, it will also run deploy
task when build
task is finished.
The syntax is simple: Run tasks? <taskNames> (before|after) this (in parallel)?
where each task name is surrounded by a pair of backticks: `
.
Examples:
Run task `build` after this.
Run tasks `build:app` `start:server` before this.
Run tasks `build:server` `build:client` before this in parallel.
Like npm scripts, when you run a command called build
, when it's finished we will also run postbuild
task.
Hook syntax:
pre<taskName>
: Run before a specific task.post<taskName>
: Run after a specific task.afterAll
: Run after all tasks.beforeAll
: Run before all tasks.
The CLI arguments are passed to executed script, so you can access it like this:
## log
```bash
echo $1
```
Then run maid log nice
and it will print nice
in the console.
The JS script will also be evaluated.
## log
```js
console.log(process.argv)
```
For asynchonous tasks, you can export a function which returns Promise:
## build
```js
module.exports = async () => {
const files = await readFiles('./')
await buildFiles(files)
}
```
## log
```py
print("cool")
```
By default, Maid would use maidfile.md
or README.md
(case-insensitive) in current working directory, when you're using README.md
you need to manually specify the section of the markdown you wanna use as Maid tasks like below:
## My Project
## How to use
Let me explain..
## Development
<!-- maid-tasks -->
### test
```bash
# some test scripts...
```
Unlike a maidfile.md
which uses all h2
headers as tasks, in README.md
only h3
headers under the specified h2
header will be used as tasks. You can add a <!-- maid-tasks -->
comment right below the desired h2
header.
Alternatively, if you're not using maidfile.md
, you can also use --section h2_header
and --path foo.md
flags to customize it.
Maid's own development scripts are powered by itself, run maid help
or node bin/cli help
in this project to get more.
Run ESLint to ensure code quality and code style (via Prettier).
yarn eslint . "${@:1}"
If you want to automatically fix lint errors, try adding --fix
plugin to the command you run, e.g. maid lint --fix
Use AVA to run unit tests.
yarn ava "${@:1}"
Similar to the lint
task, you can append any flags for ava
command directly when you run the maid command.
Generate a table of contents section in the README.md file.
yarn doctoc README.md
