# Pelias Sofware requirements
|
||
|
|
|
||
|
|
This is the list of all software requirements for Pelias. We highly recommend using our
|
||
|
|
[Docker images](https://hub.docker.com/r/pelias/) to avoid having to even attempt to correctly
|
||
|
|
install all our dependencies yourself.
|
||
|
|
|
||
|
|
## Node.js
|
||
|
|
|
||
|
|
Version 6 or newer
|
||
|
|
|
||
|
|
Most Pelias code is written in Node.js. Node.js 8 is recommended.
|
||
|
|
Node.js 10 is not as well tested with Pelias yet, but should offer notable performance increases and
|
||
|
|
may become the recommendation soon.
|
||
|
|
|
||
|
|
We will probably drop support for Node.js 6 in the near future, so that we can use the many features
|
||
|
|
supported only in version 8 and above.
|
||
|
|
|
||
|
|
## Elasticsearch
|
||
|
|
|
||
|
|
Version 2.3 or 2.4
|
||
|
|
|
||
|
|
The core data storage for Pelias is Elasticsearch. We recommend the latest in the 2.4 release line.
|
||
|
|
|
||
|
|
We do not _yet_ support Elasticsearch 5 or 6, but work is [ongoing](https://github.com/pelias/pelias/issues/461)
|
||
|
|
|
||
|
|
## SQLite
|
||
|
|
|
||
|
|
Version 3.11 or newerr
|
||
|
|
|
||
|
|
Some components of Pelias need a relational database, and Elasticsarch does not provide good
|
||
|
|
relational support. We use SQLite in these cases since it's simple to manage and quite performant.
|
||
|
|
|
||
|
|
## Libpostal
|
||
|
|
|
||
|
|
Pelias relies heavily on the [Libpostal](https://github.com/openvenues/libpostal#installation)
|
||
|
|
address parser. Libpostal requires about 4GB of disk space to download all the required data.
|
||
|
|
|
||
|
|
## Windows Support
|
||
|
|
|
||
|
|
Pelias is not well tested on Windows, but we do wish to support it, and will accept patches to fix
|
||
|
|
any issues with Windows support.
