Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Manticore Search index dump utility

Used for logical backup of indexes and exceptions, stopwords and wordforms files. For a physical backup of the index files, use indexbackup

To work correctly, all text fields must be stored. If the field is only indexed - you can not get the original data. If the index specifies absolute path for the exceptions, stopwords and wordforms files, they are required for backup. File paths are automatically changed to current_directory/index_name/file_name. To backup these files, you need to have read access or use sudo

WARNING: Testing only on Manticore Search 5 for RT indexes

Quick start

Install

:/var/backup# yarn global add indexdump

Check backup possibility

:/var/backup# indexdump --dry-run test_index

Backup

:/var/backup# indexdump test_index > test_index.tar.gz

Full sample dump to AWS s3

Install and config aws cli

For this example, you must have aws-cli configured

Dumping indexes is associated with transferring large amounts of data, so you need to set the chunk size for aws s3

I use eu-central-1 but you can choose any available

# ~/.aws/config
[default]
region = eu-central-1
output = json
s3 =
    multipart_chunksize = 256MB

Create bucket

:/var/backup# aws s3 mb s3://bucketname --region=eu-central-1

Check result

:/var/backup# aws s3 ls

Check possibility for dump

:/var/backup# indexdump --dry-run limit=10 --all 

Create dump and send to aws s3 in stream

:/var/backup# indexdump --add-drop-index --all | aws s3 cp - s3://bucketname/alldump.tar.gz

Restore

Extract exceptions, stopwords and wordforms files

aws s3 cp s3://bucketname/alldump.tar.gz - | tar -C . -xzf --exclude="dump.sql" -

Restore indexes dump

aws s3 cp s3://bucketname/alldump.tar.gz - | tar -xOzf - dump.sql | mysql -P9306
