## Setup your environment
|
||
|
|
|
||
|
|
To productively get going with Deno you should set up your environment. This
|
||
|
|
means setting up shell autocomplete, environmental variables and your editor or
|
||
|
|
IDE of choice.
|
||
|
|
|
||
|
|
### Environmental variables
|
||
|
|
|
||
|
|
There are several env vars that control how Deno behaves:
|
||
|
|
|
||
|
|
`DENO_DIR` defaults to `$HOME/.deno` but can be set to any path to control where
|
||
|
|
generated and cached source code is written and read to.
|
||
|
|
|
||
|
|
`NO_COLOR` will turn off color output if set. See https://no-color.org/. User
|
||
|
|
code can test if `NO_COLOR` was set without having `--allow-env` by using the
|
||
|
|
boolean constant `Deno.noColor`.
|
||
|
|
|
||
|
|
### Shell autocomplete
|
||
|
|
|
||
|
|
You can generate completion script for your shell using the
|
||
|
|
`deno completions <shell>` command. The command outputs to stdout so you should
|
||
|
|
redirect it to an appropriate file.
|
||
|
|
|
||
|
|
The supported shells are:
|
||
|
|
|
||
|
|
- zsh
|
||
|
|
- bash
|
||
|
|
- fish
|
||
|
|
- powershell
|
||
|
|
- elvish
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```shell
|
||
|
|
deno completions bash > /usr/local/etc/bash_completion.d/deno.bash
|
||
|
|
source /usr/local/etc/bash_completion.d/deno.bash
|
||
|
|
```
|
||
|
|
|
||
|
|
### Editors and IDEs
|
||
|
|
|
||
|
|
Because Deno requires the use of file extensions for module imports and allows
|
||
|
|
http imports, and the most editors and language servers do not natively support
|
||
|
|
this at the moment, many editors will throw errors about being unable to find
|
||
|
|
files or imports having unnecessary file extensions.
|
||
|
|
|
||
|
|
The community has developed extensions for some editors to solve these issues:

If you don't see your favorite IDE on this list, maybe you can develop an
|
||
|
|
extension. Our [community Discord group](https://discord.gg/TGMHGv6) can give
|
||
|
|
you some pointers on where to get started.
