|
|
|
|
|
|
|
|
|
|

|
|
|

|
|
|
|
|
|
|
## nodenv
|
|
|
|
|
|
|
|
|
|
[_nodenv_][5] does one thing well - it is concerned solely with switching
|
|
|
|
|
Node versions. It is simple and predictable, Just Works, and is rock solid in
|
|
|
|
|
production. nodenv is forked from the popular [_rbenv_][6].
|
|
|
|
|
|
|
|
|
|
This will be loaded automatically if nodenv is installed in `$NODENV_ROOT`,
|
|
|
|
|
_`$XDG_CONFIG_HOME/nodenv`_, _`~/.nodenv`_, or `nodenv` is on the path.
|
|
|
|
|
|
|
|
|
|
## nvm
|
|
|
|
|
|
|
|
|
|
[_nvm_][7] allows for managing multiple, isolated Node.js installations in the
|
|
|
|
|
home directory.
|
|
|
|
|
|
|
|
|
|
This will be loaded automatically if nvm is installed in `$NVM_DIR`,
|
|
|
|
|
_`$XDG_CONFIG_HOME/nvm`_, _`~/.nvm`_, or is installed with homebrew.
|
|
|
|
|
|
|
|
|
|
## Functions
|
|
|
|
|
|
|
|
|
|
- `node-doc` opens the Node.js online [API documentation][3] in the default
|
|
|
|
|
browser.
|
|
|
|
|
- `node-info` exposes information about the Node.js environment via the
|
|
|
|
|
`$node_info` associative array.
|
|
|
|
|
|
|
|
|
|
## Theming
|
|
|
|
|
|
|
|
|
|
To display the version number of the current Node.js version, define the
|
|
|
|
|
following style inside the `prompt_name_setup` function.
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
# %v - Node.js version.
|
|
|
|
|
zstyle ':prezto:module:node:info:version' format 'version:%v'
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Then add `$node_info[version]` to either `$PROMPT` or `$RPROMPT` and call
|
|
|
|
|
`node-info` in `prompt_name_preexec` hook function.
