# Code Intelligence **(FREE)**
2020-07-28 23:09:34 +05:30
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/1576) in GitLab 13.1.
Code Intelligence adds code navigation features common to interactive
development environments (IDE), including:
- Type signatures and symbol documentation.
2020-10-24 23:57:45 +05:30
- Go-to definition.
2020-07-28 23:09:34 +05:30
Code Intelligence is built into GitLab and powered by [LSIF ](https://lsif.dev/ )
(Language Server Index Format), a file format for precomputed code
intelligence data.
2021-04-17 20:07:23 +05:30
NOTE:
You can automate this feature in your applications by using [Auto DevOps ](../../topics/autodevops/index.md ).
2020-07-28 23:09:34 +05:30
## Configuration
Enable code intelligence for a project by adding a GitLab CI/CD job to the project's
2021-04-17 20:07:23 +05:30
`.gitlab-ci.yml` which generates the LSIF artifact:
2020-07-28 23:09:34 +05:30
```yaml
code_navigation:
2020-11-24 15:15:51 +05:30
image: sourcegraph/lsif-go:v1
2020-07-28 23:09:34 +05:30
allow_failure: true # recommended
script:
- lsif-go
artifacts:
reports:
lsif: dump.lsif
```
2021-01-29 00:20:46 +05:30
The generated LSIF file size may be limited by
the [artifact application limits (`ci_max_artifact_size_lsif`) ](../../administration/instance_limits.md#maximum-file-size-per-type-of-artifact ),
default to 100MB (configurable by an instance administrator).
2020-07-28 23:09:34 +05:30
After the job succeeds, code intelligence data can be viewed while browsing the code:

## Language support
Generating an LSIF file requires a language server indexer implementation for the
relevant language.
| Language | Implementation |
|---|---|
2021-01-03 14:25:43 +05:30
| Go | [`sourcegraph/lsif-go` ](https://github.com/sourcegraph/lsif-go ) |
| JavaScript | [`sourcegraph/lsif-node` ](https://github.com/sourcegraph/lsif-node ) |
| TypeScript | [`sourcegraph/lsif-node` ](https://github.com/sourcegraph/lsif-node ) |

refer to their documentation to see how to generate an LSIF file for your specific language.
